155Mbps, SFF LC Duplex Optical Transceiver Module for

Fast Ethernet, ATM, SONET/SDH STM-1/OC-3

Features：

 Full Compliance with the Optical Performance

Requirements of the ATM 100Mbps and 100

Base-LX Version of IEEE 802.3u.

 Multisource 2x5 package styles with LC

Receptacle.

 Single 3.3V Power Supply.

 PECL Differential Inputs and Outputs.

 PECL（LC-155B2xxxxx x Series） or TTL

（LC-155B4xxxxxx Series）Receiver Signal

Detect Indicator.

 Wave Solder and Aqueous Was h Process

Compatible.

 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 p rovide s the final

pulse shaping for the logic output and the Signal

Detect function. The data output is differential. The

signal detect output is single-e nded.

Application：

 Single-mode Fiber Backbone Links.

 Fast Ethernet and ATM Compatible.

 Single-mode Fiber Media Converter.
