Brief Introduction
The GPON OLT SFP transceiver is the high performance module for single fiber by using 1490nm continuous-mode transmitter and 1310nm burst-mode receiver. It is optical line terminal(OLT) for ITU-T G984.2. The optical transceiver is compliant with the Small Form- Factor Pluggable (SFP) Multi-Source Agreement (MSA). 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.The receiver has a hermetically packaged burst-mode APD-TIA (trans-impedance amplifier) pre-amplifier and a burst-mode limiting amplifier with LVPECL compatible differential outputs.The receiver also includes the function of burst mode signal detect output and fast RSSI output which is enabled by a trigger. When the burst optical power is on, the receiver outputs high level; when the burst optical power is off, the receiver outputs low level. Fast RSSI function can satisfy more severe timing demand to monitor the power from any ONU.

 | Optical transceivers port(SC) For SC port, there are two types of single-fiber bidirectional optical transceivers (one SC connector) and dual-fiber unidirectional optical transceiver (two SC connectors). Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals. |
