Description：

The LC-155Bxxxx 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-155Bxxxx transceivers are supplied in 2x5

DIP package style with duplex LC connector and

are fully complaint with SFF Multi Source

Agreement （MSA）.

All LC-155Bxxxx 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：

z Single-mode Fiber Backbone Links.

z Fast Ethernet and ATM Compatible.

z Single-mode Fiber Media Converter.
