(LC-155B4xxxxxx Series) Receiver Signal 
Detect Indicator. 
 RoHS Compliance 
 Wave Solder and Aqueous Wash Process 
Compatible. 
Description: 
The LC-155Bxxxxxxx series 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-155Bxxxxxxx transceivers are supplied in  2
×5 DIP package style with duplex LC connector and 
are fully compliant with SFF Multi-Source Agreement 
(MSA). 
 
The LC-155Bxxxxxxx transceivers can meet Class-1 
eye safety standard and effective distance depending 
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 
drives it. 
 
The receiver sections utilize InGaAs PIN photodiodes 
coupled into a custom silicon trans-impedance 
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.
