OPT-155Axxxx
155Mbps 1x9 SC/ST 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-FX Version of IEEE 802.3u.
Industry Standard 1x9 Footprint and Duplex
SC or ST Connector Interface.
Single 5V（OPT-155A1Hxx）or 3.3V
（OPT-155A2Hxx）Power
Supply.
PECL Differential Inputs and Outputs.
PECL Receiver Signal Detect Indicator.
Wave Solder and Aqueous Wash Process
Compatible.
RoHS Compliant per Directive 2002/95/EC
Description：
The OPT-155AxHxx series are 1x9 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 OPT-155AxHxx transceivers are supplied in
industry standard 1x9 SIP package style with either
duplex SC or duplex ST connector. Moreover the
OPT-155AxHx series also include a Signal-Detect
circuit that provides PECL logic output state.
The OPT-155AxHxx series meet Class-1 eye safety
standard and effective distance up to 2Km.
The transmitter sections utilize 1310nm Surface
Emitting InGaAsP LEDs. These LEDs are packaged
in the optical subassembly portion of the transmitter
section. A custom silicon IC that converts differential
PECL logical signals into an analog LED 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：
Multimode Fiber Backbone Links.
Fast Ethernet and ATM Compatible.
Multimode Fiber Media Converter.
