‹
Operating case temperature: 0 to +70℃
The transceiver consists of two sections: The
transmitter section incorporates an uncooled DFB
laser, and the receiver section consists of a PIN
photodiode 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.

Regulatory Compliance
The transceivers have been tested according to American and European product safety and electromagnetic
compatibility regulations (See Table 1). For further information regarding regulatory certification, please refer
to FlexonTM regulatory specification and safety guidelines, or contact Fiberxon, Inc. America sales office listed
at the end of the documentation.

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.

Notes:
1. TX Fault is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the host
board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates a
laser fault of some kind. In the low state, the output will be pulled to less than 0.8V.
2. TX Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the
module with a 4.7k~10kΩ resistor. Its states are:
Low (0~0.8V):

3. MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7k~10kΩ resistor on
the host board. The pull-up voltage shall be VccT or VccR.
MOD-DEF 0 grounded by the module indicates that the module is present
MOD-DEF 1 is the clock line of two-wire serial interface for serial ID
MOD-DEF 2 is the data line of two-wireserial interface for serial ID
4. LOS is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the host board to
a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
In the low state, the output will be pulled to less than 0.8V.
5. These are the differential receiver outputs. They are AC-coupled 100Ω differential lines which should be
terminated with 100Ω (differential) at the user SERDES.
6. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential
termination inside the module.
