Description：

The OPT-155AxHxx 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-155AxHxx transceivers are supplied in industry standard 1x9 SIP package style with either duplex SC or duplex ST connector. Moreover the OPT-155AxHx series also include a Signal-Detect circuit that provides PECL logic output state.

The OPT-155AxHxx series meet Class-1 eye safety standard and effective distance up to 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 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.
