SFP 1.25Gbps 80km Duplex LC Transceiver


The ZKTel ZD5K803-xCLxxx transceiver with SFP package supports typically 2.5Gbps Data Rate for DWDM application up to 80km transmission distance, LC receptacle is for optical interface.


The module provides digital diagnostic information of its operating conditions and status, including transmitting power, laser bias, receiver input optical power, module temperature, and supply voltage. Calibration and alarm/warning threshold data are written and stored in internal memory (EEPROM). The memory map is compatible with SFF-8472, as shown in Fig. 2. The diagnostic data are raw A/D values and must be converted to real world units using calibration constants stored in EEPROM locations 56 – 95 in A2h.
