1.25G/1.25G OLT GPON SFP TX 1490nm RX 1310nm 20km SC Class B+ GPON OLT PX20+ Optical Transceiver Module

 Nice price brand compatible 1.25G/1.25G ONU OLT PON SFP TX 1490nm/RX 1310nm 20km 

Description

1.The GEPON OLT SFP PX20++ is the high performance module for single fiber by using 1310nm continuous-mode transmitter and 1490nm burst-mode receiver.

2.It is optical line terminal(OLT) for IEEE Std 802.3ah™ -2004 1000BASE-PX20. The optical transceiver is compliant with the Small Form- Factor Pluggable (SFP) Multi-Source Agreement (MSA).

3.The transmitter section uses a 1490nm DFB LD with automatic power control (APC) function and temperature compensation circuitry to ensure stable extinction ratio over all operating temperature range. and is ClassⅠlaser compliant IEC825 and CDRH standards.

4.The receiver has a hermetically packaged APD-TIA (trans-impedance amplifier) pre-amplifier and a limiting amplifier with LVPECL compatible differential outputs.

5.The receiver also supports burst mode RSSI output which is enabled by a trigger. Burst mode RSSI function can satisfy system the demand of monitoring the power from any ONU.
