Description
Fiberxon’s
FTM-5112C-SL80G,
1.25Gbps
SFP
transceivers are high performance, cost effective
modules. They are designed for Gigabit Ethernet
Features
1.25Gbps bi-directional data links
80km transmission distance with SMF
1550nm DFB laser transmitter
SFP MSA package with LC optical receptacle
With Spring 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℃
applications for 80km distance with SMF.
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.

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.

EEPROM Information
The SFP MSA defines a 256-byte memory map in EEPROM describing the transceiver’s capabilities,
standard interfaces, manufacturer, and other information, which is accessible over a 2-wire serial interface at
the 8-bit address 1010000X (A0h). The memory contents refer to Table 5.
