The SFF-PTHSW/LW-2X5/2X6 conforms to the American National Standards Institute's (ANSI) Fibre Channel, FC-PI specification for short and long wavelength operation (200-M5-SN-I, 200-M6-SN-I,100-M5-SN-I,100M6-SN-I, 200-SM-LC-L, and 100-SM-LC-L). The transceiver is insensitive to the data rate of the incoming electrical and optical signals. The transceiver complies with the 1.0625Gb/s Fibre Channel specification and 2.125Gb/s FC Standard without an external control signal. The SFF-PTH-SW/LW-2X5/2X6 is ideally suited for Fibre Channel applications which include point to point links as well as Fibre Channel Arbitrated Loop (FC-AL). It can also be used for other serial applications where high data rates are required. This specification applies to a pin through hole (PTH) module which has a 2 by 5 electrical connector pin configuration. The SFF-PTH-2125-SW uses a short wavelength (850nm) VCSEL (Vertical Cavity Surface Emitting Laser) source. This enables low cost data transmission over optical fibers at distances up to 500m at 1.0625Gb/s and 300m at 2.125Gb/s. A 50/125m multimode optical fiber, terminated with an industry standard LC connector, is the preferred medium. (A 62.5/125m multimode fiber can be substituted with shorter maximum link distances.) The SFF-PTH-LW uses a long wavelength (1310nm) edge emitting laser. This enables data transmission over optical fibers at distances up to 10,000 m on a single mode (9/125m) optical fiber. Encoded (8B/10B) [3], [4], gigabit/sec serial differential PECL signals traverse a PTH connector interfacing the SFF-PTH-SW/LW-2X5/2X6 to the host card. The serial data modulates the laser and is sent out over the outgoing fiber of a duplex cable. Incoming modulated light is detected by a photoreceiver mounted in the LC receptacle. The optical signal is converted to an electrical one, amplified and delivered to the host card. This module is designed to work with industry standard "10b" Serializer/Deserializer modules. The SFF-PTH-SW/LW-2X5/2X6 is a Class 1 laser safe product. The optical power levels, under normal operation, are at eye safe levels. Optical fiber cables can be connected and disconnected without shutting off the laser transmitter. w.D a taS hee t4U .co m ww 03/14/01 Page 1 of 23 www..com IBM42F21SNNAA10 IBM42G21SNNAA10 IBM42F21LNNAA10 IBM42G21LNNAA10 2x / 1x Fibre Channel Small Form Factor PTH Transceiver Package Outline Pin Assignments Pin Name Rx Ground Rx Power Rx_SD Rx_DAT Rx_DAT + Tx Power Tx Ground Tx_Disable Tx_DAT + Tx_DAT N/C Tx_Fault (2X6 Only) Type Ground Power Status Out Signal Out Signal Out Power Ground Control In Signal In Signal In Not Connected Status Out Pin # 1 2 3 4 5 6 7 8 9 10 A B Ordering Information Product Descriptor SFF-PTH-2125-SW-2X5 SFF-PTH-LW-2X5 SFF-PTH-2125-SW-2X6 SFF-PTH-LW-2X6 Part Number IBM42F21SNNAA10 IBM42F21LNNAA10 IBM42G21SNNAA10 IBM42G21LNNAA10 Maximum Signaling Rate 2.125Gb/s 2.125Gb/s 2.125Gb/s 2.125Gb/s Wavelength 850nm 1310nm 850nm 1310nm Laser Safety Compliance Requirements The SFF-PTH-SW/LW-2X5/2X6 is designed and certified as a Class 1 laser product. If the power supply voltage exceeds 4.0 volts, the transceiver may no longer remain a Class 1 product. The system using the SFF-PTH-SW/LW-2X5/2X6 must provide power supply over voltage protection that guarantees the supply does not exceed 4.0 volts under all fault conditions. taS hee t4U .co contained in EN 60825.

ESD Notice It is advised that normal static precautions be taken in the handling and assembly of the SFF-PTHSW/LW-2X5/2X6 to prevent damage and/or degradation which may be introduced by electrostatic discharge. Caution: Operating the power supply above 4.0V or otherwise operating the SFF-PTH-SW/LW-2X5/2X6 in a manner inconsistent with its design and function may result in hazardous radiation exposure, and may be considered an act of modifying or new manufacturing of a laser product under US regulations contained in 21 CFR(J) or CENELEC regulations w.D a ww Page 2 of 23 m 03/14/01 www..com IBM42G21SNNAA10 IBM42F21SNNAA10 IBM42G21LNNAA10 IBM42F21LNNAA10 2x / 1x Fibre Channel Small Form Factor PTH Transceiver Block Diagram Optical Receive Section Electrical Fiber Input Photoreceiver Post-amp and Signal Detect +Rx_DAT -Rx_DAT Rx_SD Transmit Section Fiber Output Laser AC Modulation -Tx_DAT +Tx_DAT DC Drive and Safety Control Fault Sense Tx_Disable Tx_Fault (Only available on 2 X 6) w.D a taS hee t4U .co Transmit Section The input, an AC coupled differential data stream from the host, enters the AC Modulation section of the laser driver circuitry where it modulates the output optical intensity of a semiconductor laser. The DC Drive maintains the laser at the correct preset power level. In addition, safety circuits in the DC Drive will shut off the laser if a fault is detected. The transceiver provides the AC coupling for the +Tx/-Tx lines. No AC coupling capacitors are required on the host card for proper operation. Receive Section The incoming modulated optical signal is converted to an electrical signal by the photoreceiver. This electrical signal is then amplified and converted to a differential serial output data stream and delivered to the host. A transition detector detects sufficient AC level of modulated light entering the photoreceiver. This signal is provided to the host as a signal detect status line. The transceiver provides the AC coupling for the +Rx/-Rx lines. No AC coupling capacitors are required on the host card for proper operation. m ww 03/14/01 Page 3 of 23 www..com IBM42F21SNNAA10 IBM42G21SNNAA10 IBM42F21LNNAA10 IBM42G21LNNAA10 2x / 1x Fibre Channel Small Form Factor PTH Transceiver Input Signal Definitions Levels for the signals described in this section are listed in Transmit Signal Interface on page 8 and Control Electrical Interface on page 9. Tx_DAT A differential PECL serial data stream is presented to the SFF-PTH-SW/LW-2X5/2X6 for transmission onto an optical fiber by modulating the optical output intensity of the laser. Tx_Disable When high (a logical one), the Tx_Disable signal turns off the power to both the AC and DC laser driver circuits. It will also reset a laser fault if one should happen. When low (a logical zero), the laser will be turned on within 1 ms if a hard fault is not detected. The transceiver contains a pull-down resistor to enable the laser when the line is not connected on the host side. If driven, this line should be connected to a push-pull output driver.

Rx_DAT The incoming optical signal is converted and repowered as a differential PECL serial data stream. The Receive Signal Interface table on page 8 gives the voltage levels and timing characteristics for the Rx_DAT signals. Rx_SD The Receive Signal Detect line is high (a logical one) when the incoming modulated light intensity is sufficient for reliable operation. This is the state for normal operation. The line is low (a logical zero) when incoming modulated light intensity is the below that required to guarantee the correct operation of the link. Normally, this only occurs when either the link is unplugged or the companion transceiver is turned off. This signal is normally used by the system for diagnostic purposes. This signal has a push-pull output driver. Tx_Fault (Only available on 2 X 6) Upon sensing an improper power level in the laser driver, the SFF sets this signal high and turns off the laser. The Tx_Fault signal can be reset with the Tx_Disable line. The laser is turned off within 100 s as shown in the Transmitter Fault Detection timing diagram below. This signal has an open drain TTL driver. A pull up resistor is required on the host side of the SFF connector.

Continuous resetting and re-powering of the laser under a hard fault condition could cause a series of optical pulses with sufficient energy to violate laser safety standards. To alleviate the possibility of violating laser safety standards, the SFF-PTH-SW/LW-2X5/2X6 will turn off the laser if a second fault is detected within 25 ms of the laser powering on. This lock is cleared during each power on cycle. Please refer to the timing diagrams below.

The minimum and maximum values of the average received power in dBm give the input power range to maintain a BER < 10-12 when the data is sampled in the center of the receiver eye. These values take into account power penalties caused by the use of a laser transmitter with a worst-case combination of spectral width, extinction ratio and pulse shape characteristics. 2. Optical Modulation Amplitude (OMA) is defined as the difference in optical power between a logic level one and a logic level zero. The Optical Modulation Amplitude is defined in terms of average optical power (PAVG in W) and extinction ratio (ER) as given by OMA=2PAVG((ER-1)/(ER+1)). The extinction ratio, defined as the ratio of the average optical power (in W) in a logic level one to the average optical power in a logic level zero measured under fully modulated conditions in the presence of worst case reflections, must be the absolute (unitless linear) ratio and not expressed in dB.The specified Optical Modulation Amplitude at 2.125Gb/s is equivalent to an average power of -15 dBm at an extinction ratio of 9 dB. At 1.0625Gb/s, the specified OMA is equivalent to an average power of -17 dBm at an ER of 9 dB. 3. The Rx_SD has hysteresis to minimize "chatter" on the output line. In principle, hysteresis alone does not guarantee chatter-free operation. The SFF-PTH-SW/LW-2X5/2X6, however, presents an Rx_SD line without chatter, where chatter is defined as a transient response having a voltage level of greater than 0.5 volts (in the case of going from the negate level to the assert level) and of any duration that can be sensed by the host logic. w.D a taS hee t4U .co Page 10 of 23 m ww 03/14/01 www..com IBM42G21SNNAA10 IBM42F21SNNAA10 IBM42G21LNNAA10 IBM42F21LNNAA10 2x / 1x Fibre Channel Small Form Factor PTH Transceiver Transmitter Specifications Symbol C PT Trise/Tfall OMA OMA RIN12 Parameter Spectral Center Wavelength Spectral Width Launched Optical Power Optical Rise/Fall Time Optical Modulation Amplitude (2.125Gb/s) Optical Modulation Amplitude (1.0625Gb/s) Relative Intensity Noise Eye Opening DJ CPR Deterministic Jitter Coupled Power Ratio 9 0.56 0.26 196 156 -117 -10 Min 830 Typical Max. 860 0.85 -4.0 150 Unit nm nm (rms) dBm (avg) ps W (pk-pk) W (pk-pk) dB/Hz UI UI dB 1 2 3 3 4 5 6 7 Notes 1. Launched optical power is measured at the end of a two meter section of a 50/125m fiber (N.A.=0.20). The maximum and minimum of the allowed range of average transmitter power coupled into the fiber are worst case values to account for manufacturing variances, drift due to temperature variations, and aging effects. The minimum launched optical power specified assumes an infinite extinction ratio at the minimum specified OMA. 2. Optical transition time is the time interval required for the rising or falling edge of an optical pulse to transition between the 20% and 80% amplitudes relative to the logical 1 and 0 levels. This is measured through a 4th order Bessel -Thompson filter with 0.75 * Data Rate 3-dB bandwidth and corrected to the full bandwidth value. 3. Optical Modulation Amplitude (OMA) is defined as the difference in optical power between a logic level one and a logic level zero. The Optical Modulation Amplitude is defined in terms of average optical power (PAVG in W) and extinction ratio (ER) as given by OMA=2PAVG((ER-1)/(ER+1)). In this expression, the extinction ratio, the ratio of the average optical power (in W) in a logic level one to the average optical power in a logic level zero measured under fully modulated conditions in the presence of worst case reflections, must be the absolute (unitless linear) ratio and not expressed in dB. The specified Optical Modulation Amplitude is equivalent to an average power of -9 dBm at an extinction ratio of 9 dB. 4. RIN12 is the laser noise, integrated over a specified bandwidth, measured relative to average optical power with 12dB return loss. See ANSI Fibre Channel Specification Annex A. 5. Eye opening is the portion of the bit time where the bit error rate (BER) 10-12. 1.0625Gb/s values meet the criteria listed in Ref [1]. 6. Deterministic Jitter is measured as the peak-to-peak timing variation of the 50% optical signal crossings when transmitting repetitive K28.5 characters. It is defined in FC-PH, version 4.3, clause 3.1.87 as: w.D a taS hee t4U .co Timing distortions caused by normal circuit effects in the transmission system. Deterministic jitter is often subdivided into duty cycle distortion (DCD) caused by propagation differences between the two transitions of a signal and data dependent jitter (DDJ) caused by the interaction of the limited bandwidth of the transmission system components and the symbol sequence. 1.0625Gb/s values meet the criteria listed in Ref [1]. 7.

Deterministic jitter is often subdivided into duty cycle distortion (DCD) caused by propagation differences between the two transitions of a signal and data dependent jitter (DDJ) caused by the interaction of the limited bandwidth of the transmission system components and the symbol sequence. 1.0625Gb/s values meet the criteria listed in Ref [1]. w.D a taS hee t4U .co m ww 03/14/01 Page 13 of 23 www..com IBM42F21SNNAA10 IBM42G21SNNAA10 IBM42F21LNNAA10 IBM42G21LNNAA10 2x / 1x Fibre Channel Small Form Factor PTH Transceiver Optical Cable and Connector Specifications (Short Wavelength) Symbol Parameter Min Typical Max.

The HBM (human body model) is a 100 pF capacitor discharged through a 1.5 k resistor into each pin per JESD22-A114-B. 2. Complies with European ESD Immunity Test (C-B-2-0001-034). Soldering Information The SFF transceiver comes with a process/dust plug. When the plug is in place the transceiver can withstand normal wave soldering and aqueous spray cleaning processes. While the transceiver is able to withstand an aqueous cleaning process, it is not hermetically sealed; it was not designed to be immersed in cleaning solvents. An opening in the back of the top lid is to allow compressed air to be blown into the module to aid in the removal of trapped water. This process should be performed after aqueous cleaning with the plug still inserted. If the plug was not contaminated during the wave soldering and aqueous spray cleaning process it can be reused as a dust plug. w.D a taS hee t4U .co Page 16 of 23 m ww 03/14/01 www..com IBM42G21SNNAA10 IBM42F21SNNAA10 IBM42G21LNNAA10 IBM42F21LNNAA10 2x / 1x Fibre Channel Small Form Factor PTH Transceiver Mechanical Description (2 X 5 Pin Configuration) w.D a taS hee t4U .co The SFF-PTH-SW/LW-2X5/2X6 is intended to be used on a host card having a thickness of 0.062" to 0.100".
