The transceiver is small form factor pluggable mod ule with standard duplex c onnector for fiber communications This module is designed for single mode fiber ( and operates at a nominal wav elength of 1 550 nm with cost effective and high performance It is with the SFP 20 pin connector to allow hot plug capability.
The transmitter consists of a high performance 1 550 nm MQW DFB structure laser in the optical subassembly (OSA), which is housed within a metal package. In addition, this component is also class 1 laser compliant with according to International Safety Standard IEC 825 Compliant . Complies with EN60825 1 and FDA 21 CFR 1040.10 an d 1040.11.
The receiver contain of a n In GaAs PIN photodiode coupled to a high sensitivity transimpedance amplifier(TIA) in an OSA. This OSA combination is mated to a post amplifier IC that provides the post amplification and SD (Signal Det ection) or LOS (Loss of Signal) indication circuit, which provides logic high state output when an unusable input optical signal level is detected.
