| 14 Pin DIL Uncooled Laser Modules Technical Data LSC3X00 Features * Low Cost Plastic Package (14 Pin DIL) * LSC3300: 100 W (-10 dBm) Min. Power Output LSC3100: 1 mW (0 dBm) Min. Power Output * 1280 - 1330 nm Wavelength * Hermetic Laser Module * -40C to +85C Operation Description LSC3X00 laser modules are high reliability fiber optic light sources operating in the 1300 nanometer band. They are particularly well suited for applications where low power dissipation is required. The internal semiconductor lasers are based upon InGaAsP buried heterostructure (BH) technology and fabricated by the MetalOrganic Vapor Phase Epitaxy (MOVPE) process, resulting in long lifetimes and modest threshold currents. The LSC3X00 package includes a photodiode for monitoring the laser output. A longhorn type heatsink mounting flange is incorporated in the industry standard 14 pin DIL package. Two basic varieties are offered for alternative power ranges. The "low power" LSC3300 covers the power range between 100 W Applications * Telecommunications * Local Area and Metropolitan Area Networks * Point to Point Datacommunications * Fiber Optic Sensors * Cable Television * Military Communications and Control Systems * Instrumentation and 625 W. The "high power" LSC3100 uses the same laser chip, but with tighter fiber coupling to achieve output powers from 1 mW to 2.5 mW. The low cost outer package is made feasible by our unique design of hermetic miniature laser submodule which houses the electro-optic devices. The submodule concept is used as a building block in many other Hewlett-Packard products including cooled 1 mW 14 pin lasers and DFB modules. Laser Safety Warning This device is a Class IIIb (3b) Laser Product. It may emit invisible laser radiation if operated with the fiber pigtail disconnected. To avoid possible eye damage do not look into an unconnected fiber pigtail during laser operation. Do not exceed specified operating limits. 480 5963-1125E (7/94) LSC3X00 Pin Connections and Block Diagram Top View FIBER PIGTAIL NOT CONNECTED 1 NOT CONNECTED 2 NOT CONNECTED 3 NOT CONNECTED 4 CASE GROUND 5 NOT CONNECTED 6 MONITOR PHOTODIODE CATHODE (+ve SUPPLY) 7 14 NOT CONNECTED 13 NOT CONNECTED 12 NOT CONNECTED 11 NOT CONNECTED 10 LASER ANODE (+), GROUND 9 LASER CATHODE (-) 8 MONITOR PHOTODIODE ANODE (-ve SUPPLY) LSC3X00 Mechanical Outline - Dimensions in mm Q F E L N R A BC M HG D J P K DIM.
