Description
The OPT-155AxH1A 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-155AxH1A transceivers are supplied in
industry standard 1x9 SIP package style with
duplex SC connector and include a Signal-Detect
circuit that provide PECL logic output state.
The performances of OPT-155AxH1A are better
than general LED-based optical transceivers as the
product specification. All of them can meet Class-1
eye safety standard and effective distance are 2Km
at least.
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.

OPT-155AxH1Ax Series with SC-type Connector
Note
When system Vcc is 5V, the resistors
are as below:
R1=R2=191
R3=R4=68
R5=R6=270
R7=130
R8=82
When system Vcc is 3.3V, the
resistors are as below:
R1=R2=130
R3=R4=82
R5=R6=150
R7=82
R8=130
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.
