Description：

The OPT-155Bxxxxxx 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-155Bxxxxxx transceivers are supplied in
industry standard 1x9 SIP package style with duplex
SC connector.

The OPT-155Bxxxxxx also includes a Signal-Detect
circuit that provides PECL logic output state.

The OPT-155Bxxxxxx transceivers can meet Class-1
eye safety products and effective distance depending
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
drives it.

The receiver sections utilize InGaAs PIN photodiodes
coupled into a custom silicon trans-impedance
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.
