(GPON) Class B+ OLT side
Standards:
ITU-T G.984.2 Class B+
Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement
July 5, 2000
Description:
1.The GEZHI 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).
2.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.
3.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.
