Description：
The OPT-155Bxxxx series from DELTA 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 or TTL 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.

Note：
When system Vcc is 5V, the resistors
are as below:
R1=R2=191Ω；R3=R4=68Ω
R5=R6=270Ω
For PECL Level：R7=130Ω；R8=82Ω
For TTL Level：R7、R8, No use.
When system Vcc is 3.3V, the resistors
are as below:
R1=R2=130Ω；R3=R4=82Ω
R5=R6=150Ω
For PECL Level：R7=82Ω；R8=130Ω
For TTL Level：R7、R8, No use.
R9, R10, R11 depend on SerDes IC
specification.
For getting better EMI performance, the
Tx Vcc and Rx Vcc should isolate each
other as left photograph.
