Laser diodes

The TOLD321S-TXS1 laser diode transmitter, operating at 622 Mbits/sec, has a built-in driver integrated circuit and an automatic optical power control function that allows transmission through singlemode or multimode fiber. Model TOLD347S-TX offers 10-Gbit/sec transmission and has an automatic optical power and temperature control function. Intermediate models that offer data rates to 800 Mbits/sec and 2.5 Gbits/sec are available.The 5-Gbit/sec TOPD351-RX receiver includes an HEMT front-end amplifier and an InGaAs PIN photodiode. Its sensitivity rate is -18 dBm. The TOPD323-RXS1 15 ¥ 20 ¥ 12.7-mm receivermodule has a data rate of 622 Mbits/sec, a built-in 3R function and a sensitivity rate of -31 dBm. Two intermediate models (TOAD345-RX5 and TOAD346-RX) have 2.5-Gbit/sec data rates and feature sensitivity of -32 and -33 dBm, respectively. Laser diodes serve high-speed data communications and telecommunications applications. Pricing for the transmitters ranges from $340 to $11,197. Receiver modules cost $465 to $4479. Full production of these laser diodes is scheduled for the second quarter of 1996.
