Description
The LC-155Bxxxxxx series from DELTA are SFF Small Form Factor 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 LC-155Bxxxxxx transceivers are supplied in 2x5 DIP package style with duplex LC connector and are fully complaint with SFF Multi Source Agreement MSA .
All LC-155Bxxxxxx series can meet Class-1 eye safety standard 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.
