Base-LX Version of IEEE 802.3u.
Industry Standard 1x9 Footprint and Duplex
SC Connector Interface.
Single 5V（OPT-155B1xxx）or 3.3V

Description：
The OPT-155Bxxxx 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-155Bxxxx transceivers are supplied in
industry standard 1x9 SIP package style with
duplex SC connector.
The OPT-155Bxxxx also includes a Signal-Detect
circuit that provides PECL logic output state.
The OPT-155Bxxxx transceivers are Class-1 eye
safety products 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：
Single-mode Fiber Backbone Links.
Fast Ethernet and ATM Compatible.
Single-mode Fiber Media Converter.
