155Mbps, 2Km, 1x9 SC Duplex Optical Transceiver Module for
Fast Ethernet, ATM, SONET/SDH STM-1/OC-3
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 Connector Interface.
Single 5V OPT-155A1H1A or 3.3V
OPT-155A2H1A Power Supply.
PECL Differential Inputs and Outputs.
PECL Receiver Signal Detect Indicator.
Wave Solder and Aqueous Wash Process
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
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
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.
