2.18 CWDM DFB wavelengths laser and PIN photodetector for 80km transmission;
3.Duplex SC optical interface;
4.Standard serial ID information compatible with SFF-8053+3.3V/5Vsingle power supplyRoHS Compliant;
5.Operating case temperature: 0 to +70ºC;
2.Applications
1.Switch to Switch interface;
2.Switched backplane applications;
3.Router/Server interface;
4.Other optical transmission systems;
3.Description
The GBIC transceiver is high performance, cost effective module supporting dual data-rate of 1.25Gbps/1.0625Gbps and from 80km transmission distance with SMF.
The transceiver consists of two sections: The transmitter section incorporates a DFB laser. And the receiver section consists of a PIN photodiode integrated with a trans-impedance preamplifier (TIA). All odules satisfy class I laser safety requirements.
The optical output can be disabled by a TTL logic high-level input of Tx Disable. Tx Fault is provided to indicate degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver.
The standard serial ID information Compatible with GBIC MSA describes the transceiver's capabilities, standard interfaces, manufacturer and other information. The host equipment can access this information via the two-wire serial CMOS EEPROM protocol. For further information, please refer to SFF-8053.
Absolute Maximum Ratings
Stress in excess of the maximum absolute ratings can cause permanent damage to the module.
