INFORMATION
Description
The BD-4311S-E2CDA is the high performance GEPON SFP module for single fiber by using 1490nm continuous-mode transmitter and 1310nm burst-mode receiver. 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).
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 APD-TIA (trans-impedance amplifier) pre-amplifier and a limiting amplifier with LVPECL compatible differential outputs.
Feature
● Single Fiber Transceiver with single mode SC receptacle
● 1490nm continuous-mode 1.25G/s transmitter with DFB laser
● 1310nm burst-mode 1.25G/s receiver with APD-TIA
● Single 3.3V power supply
● LVPECL compatible data input /output
● Support more than 24dB dynamic range
● Continued mode received signal strength indication (RSSI) output
● Complies with IEEE Std 802.3ah-2004 1000BASE-PX20
● Digital diagnostic interface compliant with SFF-8472 Rev 9.4 ,
● Complies with RoHS directive (2002/95/EC)
● Operating case temperature: 0 to +70C
