The PD-LD product incorporates low threshold current, high differential quantum efficiency MQW(Multiple Quantum Well) FP semiconductor lasers whose typical total operating currents are less than 30mA. The receiver section offers a 450MHz bandwidth PIN TIA component that is ideal for digital operation at 622MB/s. These receivers deliver typically –31dBm optical sensitivity at a BER of 10-10 at OC- 12/STM4 operation. AGC allows for high optical input power. PD-LD’s BiDirectional WDM modules are built to meet the demanding requirements for ATM-PON ONU and LTU applications. See PD-LD’s other FSAN and Bidirectional Module offerings for devices optimized for 155MB/ s and 1.25 GB/s. These units combine the electro optic performance and robust mechanical integrity necessary to meet the demands of passive optical networks outlined in FSAN, ITU-G1983. The PD-LD BiDirectional modules are assembled using laser welding processes. This technique guarantees a semiconductor to optical fiber interface that remains stable over mechanical and environmental and environmental extremes. The optical semiconductor die are mounted within hermetically sealed TO can subassemblies making them impervious to contaminants and moisture. WDM BiDirectional modules are built with 1 meter long 9/125/900 um SMF28 fiber optic pigtails. These fibers may be terminated with most standard fiber optic connectors including FC, SC, ST and LC. PD-LD Inc. is now offering its next generation of WDM style BiDirectional transmitter and receiver modules operating in the 1310 and 1550nm optical windows. These devices are designed to simultaneously transmit and receive over a single optical fiber at frequencies from 10 to 450MHz. Dual wavelength bidirectional modules replace the need for a single mode fiber coupled laser diode, a fiber coupled InGaAs PIN photodiode, a discreet fiber optic WDM and a second stage optical isolator. The BiDirectional Modules combine all of these optical functions and relieve the user of having to fusion splice several discreet units together and then squeeze them onto their PCB.
