General Description
● This 1490nm DFB EPON OLT SFP transceiver is designed to transmit and receive optical data over single mode optical fiber for link length 20km.
● The transmitter input and receiver output impedance is 100 Ohms differential. Data lines are internally AC coupled.
● The module provides differential termination and reduce differential to common mode conversion for quality signal termination and low EMI.
● The transmitter converts 1.25Gbit/s serial CML electrical data into serial optical data compliant with the 10GBASE-LR standard. An open collector compatible Transmit Disable (Tx_Dis) is provided. A logic “1,” or no connection on this pin will disable the laser from transmitting. A logic “0” on this pin provides normal operation. The transmitter has an internal automatic power control loop (APC) to ensure constant optical power output across supply voltage and temperature variations. An open collector compatible Transmit Fault (TFault) is provided. TX_Fault is a module output contact that when high, indicates that the module transmitter has detected a fault condition related to laser operation or safety. The TX_Fault output contact is an open drain/collector and shall be pulled up to the Vcc_Host in the host with a resistor in the range 4.7-10 kΩ.
