LC-155Bxxxx
155Mbps, SFF LC Duplex Optical Transceiver Module for
Fast Ethernet, ATM, SONET/SDH STM-1/OC-3
Features
z Full Compliance with the Optical Performance
Requirements of the ATM 100Mbps and 100
Base-FX Version of IEEE 802.3u.
z Multisource 2x5 package styles with LC
Receptacle.
z Single 5VLC-155B1 and LC-155B3 Seriesor
3.3VLC-155B2 and LC-155B4 SeriesPower
Supply.
z PECL Differential Inputs and Outputs.
z PECLLC-155B1 and LC-155B2 Seriesor
TTLLC-155B3 and LC-155B4 Series
Receiver Signal Detect Indicator.
z Wave Solder and Aqueous Wash Process
Compatible.
Description
The LC-155Bxxxx series from DELTA are SFF
Small Form Factoroptical 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.
