Description
The DW-S2443-20CGTB 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.
