1.25G Spring-Latch SFP Transceiver
( For 120km transmission, RoHS compliant)
Members of FlexonTM Family
Compatible with FDA 21 CFR 1040.10 and
1040.11, Class I
Compatible with Telcordia GR-468-CORE

Description
Fiberxon FTM-5112C-SL120G SFP transceiver is
high performance, cost effective module supporting
dual data-rate of 1.25Gbps and 120km transmission
distance on SMF.
Features
Dual data-rate of 1.25Gbps operation
The transceiver consists of two sections: The
transmitter section incorporates a DFB laser. And
the receiver section consists of a APD photodiode
integrated with a trans-impedance preamplifier (TIA).
All modules satisfy class I laser safety requirements.
120km transmission distance with SMF
1550nm DFB laser
High sensitivity APD receiver
Monitoring interface compatible with SFF-8472
SFP MSA package with duplex LC connector
With Spring-Latch for high density application
Very low EMI and excellent ESD protection
+3.3V single power supply
The optical output can be disabled by a TTL logic
high-level input of Tx Disable. Tx Fault is provided to
indicate that degradation of the laser. Loss of signal
(LOS) output is provided to indicate the loss of an
input optical signal of receiver.
Operating case temperature: 0 to +70°C
Applications
FTM-5112C-SL120G provides an enhanced
monitoring interface, which allows real-time access
to device operating parameters such as transceiver
temperature, laser bias current, transmitted optical
power, received optical power and transceiver
supply voltage. For further information, please refer
to SFP MSA and SFF-8472 Rev 9.5.

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 with Fiberxon, Inc. America sales office
listed at the end of the documentation.

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.

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 is grounded by the module to indicate 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 wire serial 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 output. They are internally 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.
