transceiver is high performance, cost effective
module that supports data-rate up to 2.67Gbps and
transmission distance from 40km to 80km.
The transceiver consists of two sections: The
transmitter section incorporates an uncooled DFB
laser, and the receiver section consists of APD
integrated with a trans-impedance preamplifier (TIA).
All modules satisfy class I laser safety requirements.
The optical output can be disabled by a TTL logic
high-level input of Tx Disable. Tx Fault is provided to
indicate degradation of the laser. Loss of signal
(LOS) output is provided to indicate the loss of an
input optical signal of receiver.
The transceiver provides an enhanced monitoring
interface, which allows real time access to the

Note:
In light of item 5 in Annex of 2002/95/EC, “Pb in the glass of cathode ray tubes, electronic components and
fluorescent tubes.” and item 13 in Annex of 2005/747/EC , “ Lead and cadmium in optical and filter glass.” ,the
two exemptions are being concerned for Fiberxon’s transceivers, because Fiberxon’s transceivers use glass,
which may contain Pb, for components such as lenses, windows, isolators, and other electronic components.
