● RoHS Compliant per Directive 2002/95/EC.

Description：

The LC-155Bxxxxxx series from DELTA are SFF（Small Form Factor） optical transceiver modules designed expressly for high-speed communication applications that require rates of up to 155Mbps. They are all compliant with the SONET/SDH standards.

The LC-155Bxxxxxx transceivers are supplied in 2x5 DIP package style with duplex LC connector and are fully complaint with SFF Multi Source Agreement （MSA）.

All LC-155Bxxxxxx series can meet Class-1 eye safety standard and effective distance depends on ITU-T G.957 standard or power penalty.

The transmitter sections utilize 1310nm Edge Emitting InGaAsP Laser Diode. This Laser Diode is packaged in the optical subassembly portion of the transmitter section. A custom silicon IC that converts differential PECL logical signals into an analog LD driving current then drive it.

The receiver sections utilize InGaAs PIN photodiodes coupled into a custom silicon transimpedance preamplifier IC. These are packaged in the optical subassembly portion of

receiver.

These PIN / Preamplifier combinations are coupled into a custom quantizer IC which provides the final pulse shaping for the logic output and the Signal Detect function. The data output is differential. The signal detect output is single-ended.

Application：

● Single-mode Fiber Backbone Links.

● Fast Ethernet and ATM Compatible.

● Single-mode Fiber Media Converter.
