1431nm, 1451nm, 1471nm, 1491nm,. 1511nm,
1531nm, 1551nm, 1571nm, 1591nm and 1611nm,
compatible
30dB.
The transmitter section of FTM-6112C-SLxxxxxG
incorporates a highly reliable uncooled DFB laser
and the receiver section utilizes a PIN/APD receiver.
All
modules
satisfy
Class
1
Laser
Safety
requirements.
FTM-6112C-SLxxxxxG
provides
an
enhanced
with
ITU-T
G694.2.
It
offers
a
guaranteed minimum optical link budget of 22dB or
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. It also defines a sophisticated
system of alarm and warning flags, which alerts
end-users when particular operating parameters are
outside of a factory set normal range.
FTM-6112C-SLxxxxxG is compliant with RoHS.
Applications
Optical communication in Metro/Access Networks:
Switch to switch interface
Switched backplane applications
Router/Server interface
Other optical transmission systems

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 Fiberxon regulatory specification and safety guidelines, or contact with Fiberxon, Inc. America sales office
listed at the end of 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.

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 6.
