1 GBIC CWDM 80km Part no: Description General The GBIC CWDM 80km transceiver is small form factor pluggable module with standard SC duplex connector for fiber communications. This module is designed for single mode fiber and operates at a nominal wavelength of CWDM with the cost effective and high performance characteristics. There are eight central wavelengths available at present: 1470nm, 1490nm, 1510nm, 1530nm, 1550nm, 1570nm, 1590nm and 1610nm. eceiver Section The receiver contain of an InGaAs 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 LOS (Loss of Signal) indication circuit, which provides LVTTL logic high state output when a unusable input optical signal level is detected. Transmitter Section The transmitter consists of a highperformance 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 IEC60825 Features V / +5V Power Up to 1.25Gbps & CWDM 8 channels GigaBit Interface Converter MSA Compliant SC Duplex Connector EEPOM with serial ID functionality Class 1 Laser International Safety Standard IEC Compliant Temperature anges: 0 to +70 ohs Compliant Applications Gigabit Ethernet Links Fiber Channel Bridges/outers/intelligent hub and concentrators Performance Specifications Absolute Maximum atings Voltage VCC 0 7 V Storage Temperature TS Operating Temperature TOP 0 70 Lead Soldering Limits TSOLD 260/10 /sec General Specifications s Data ate B 1.25 Gbps Supported Link Length on 9/125µm SMF L 80 Km
