Description
Fiberxon’s
FTM-5112C-SL30G,
1.25Gbps
SFP
transceivers are high performance, cost effective
modules. They are designed for Gigabit Ethernet
applications for 30km distance with SMF.
Features
1.25Gbps bi-directional data links
30km transmission distance with SMF
1550nm DFB laser transmitter
SFP MSA package with LC optical receptacle
With lever latch for high density application
Single +3.3V power supply
Hot-pluggable capability
Low power dissipation
Very low EMI and excellent ESD protection
Class I laser product
Monitoring interface compatible with SFF-8472
Operation case temperature: 0℃ to 70℃
The transceiver consists of two sections: The
transmitter section incorporates a 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 that degradation of the laser. Loss of signal
(LOS) output is provided to indicate the loss of an
input optical signal of receiver.

Preliminary Data Sheet
Jan 10, 2007
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):
Transmitter on
(>0.8V, <2.0V):
Undefined
High (2.0~3.465V):
Transmitter Disabled
Open:
Transmitter Disabled
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.
