(the overall system design will affect the electromagnetic interference (emi), electrostatic discharge (esd) and immunity). emi recommendations emi behavior of each paroli module revision is evaluated and measured - in order to ensure a good and sufficient emi performance of all paroli modules. as the total emi performance will also depend on system design and to avoid electromagnetic radiation exceeding the required limits set by the standards, please take note of the following recommendations. feature standard comments esd: electrostatic discharge to the electrical pins (hbm) jedec human body model (hbm) test method eia/jesd22-a114-b (mil-std 883d method 3015.7) class 1c immunity: against electrostatic discharge (esd) to the module receptacle en 61000-4-2 iec 61000-4-2 discharges ranging from 2kv to 15 kv on the front end/face-plate/ receptacle cause no damage to module (under recommended mounting conditions). immunity: against radio frequency electromagnetic field en 61000-4-3 iec 61000-4-3 with a field strength of 3 v/m, noise frequency ranges from 10 mhz to 2ghz 1) . no effect on module performance between the specification limits. 1) this test covers high frequency bands of mobile phones. emission: electromagnetic interference (emi) fcc 47 cfr part 15, class b en 55022 class b cispr 22 noise frequency range: 30 mhz to 18 ghz; radiated emission does not exceed specified limits when measured inside a shielding enclosure with recommended cutout dimensions. typically pass with > 11 db margin to the limit (under recommended mounting conditions).
v23832-t2131-m101 v23832-r111-m101 description data sheet 11 2003-11-19 when gigabit switching components are found on a pcb (e.g. multiplexer, serializer- deserializer, clock data recovery, etc.), any opening of the chassis may leak radiation; this may also occur at chassis slots other than that of the device itself. thus every mechanical opening or aperture should be as small as feasible and its length carefully considered. on the board itself, every data connection should be an impedance matched line (e.g. micro strip, strip line or coplanar strip line). data (d) and data-not (dn) should be routed symmetrically. vias should be avoided. where internal termination inside an ic or a paroli module is not present, a line terminating resistor must be provided. the decision of how best to establish a ground depends on many boundary conditions. this decision may turn out to be critical for achieving lowest emi performance. at rf frequencies the ground plane will always carry some amount of rf noise. thus the ground and v cc planes are often major radiators inside an enclosure. as a general rule, for small systems such as pci cards placed inside poorly shielded enclosures, the common ground scheme has often proven to be most effective in reducing rf emissions. in a common ground scheme, the pci card becomes more equipotential with the chassis ground. as a result, the overall radiation will decrease. in a common ground scheme, it is strongly recommended to provide a proper contact between signal ground and chassis ground at every location where possible. this concept is designed to avoid hotspots which are places of highest radiation, caused when only a few connections between chassis and signal grounds exist. compensation currents would concentrate at these connections, causing radiation. however, as signal ground may be the main cause for parasitic radiation, connecting chassis ground and signal ground at the wrong place may result in enhanced rf emissions. for example, connecting chassis ground and signal ground at a front panel/ bezel/chassis by means of a fiber optic module may result in a large amount of radiation especially where combined with an inadequate number of grounding points between signal ground and chassis ground. thus the fiber optic module becomes a single contact point increasing radiation emissions. even a capacitive coupling between signal ground and chassis ground may be harmful if it is too close to an opening or an aperture. for a number of systems, enforcing a strict separation of signal ground from chassis ground may be advantageous, providing the housing does not present any slots or other discontinuities. this separate ground concept seems to be more suitable in huge systems. the return path of rf current must also be considered. thus a split ground plane between tx and rx paths may result in severe emi problems. the bezel opening for a transceiver should be sized so that all contact springs of the transceiver cage make good electrical contact with the face plate. please consider that the pcb may behave like a dielectric waveguide. with a dielectric constant of 4, the wavelength of the harmonics inside the pcb will be half of that in free space. thus even the smallest pcbs may have unexpected resonances.
v23832-t2131-m101 v23832-r111-m101 laser eye safety data sheet 12 2003-11-19 laser eye safety the transmitter of the ac coupled parallel optical link (paroli) is an iec 60825-1 amend. 2 class 1m laser product. it complies with fda performance standards (21 cfr 1040.10 and 1040.11) for laser products except for deviations pursuant to laser notice no. 50, dated july 26, 2001. to avoid possible exposure to hazardous levels of invisible laser radiation, do not exceed maximum ratings. the paroli module must be operated under the specified operating conditions (supply voltage can be adjusted between 3.0 v and 3.6 v) under any circumstances to ensure laser eye safety. class 1m laser product attention: invisible laser radiation. do not view directly with optical instruments. note: any modification of the module will be considered an act of ?manufacturing?, and will require, under law, recertification of the product under fda (21 cfr 1040.10 (i)). figure 6 laser emission laser eye safety design considerations to ensure laser eye safety for all input data patterns each channel is controlled internally and will be switched off if the laser eye safety limits are exceeded. a channel alerter switches the respective data channel output off if the input duty cycle permanently exceeds 57% (switching range 57 % min. - 65 % max.). the alerter will not disable the channel below an input duty cycle of 57% under all circumstances. the minimum alerter response time is 1 s with a constant high input, i.e. in the input pattern the time interval of excessive high input (e.g. ?1?s in excess of a 57% duty cycle, consecutive or non-consecutive) must not exceed 1 s, otherwise the respective channel will be switched off. the alerter switches the respective channel from off to on without the need of resetting the module if the input duty cycle is no longer violated. all of the channel alerters operate independently, i.e. an alert within a channel does not affect the other channels. to decrease the power consumption of the module unused channel inputs can be tied to high input level. in this way a portion of the supply current in this channel is triggered to shut down by the corresponding alerter. laser aperture and beam file: 3506
