FTM-3128C-L15x
155M~2.67G 1310nm SFP with monitoring function
Preliminary Datasheet
Dec. 20 2003
Product Description
FTM-3128C-L15x SFP transceiver is fully compliant with the SFP Multi-Source Agreement. It is
designed to provide SDH/SONET compliant links at data rates from 155Mbps to 2.67Gbps and
also can be used in Gigabit Ethernet and Fibre Channel equipments.
The transmitter section of FTM-3128C-L15x incorporates a highly reliable 1310nm DFB laser. And
the receiver section consists of a InGaAs/InP PIN photodiode mounted together with a

trans-impedance preamplifier (TIA). All modules satisfy Class 1 Laser Safety requirements.
Low Power Dissipation
By utilizing the latest chipset technology, FTM-3128C-L15x realizes low power dissipation. Typical
current is 210mA, at +3.3V operation, only 70% of the maximum current allowed by the SFP
specification (300mA).
Spring latch For High Density Application
FTM-3128C-L15x features a spring latch that allows user to easily remove the SFP transceiver by
hand even in high-density application.
Monitoring Interface Compliant With SFF-8472
FTM-3128C-L15x 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. 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.
The monitoring interface makes use of 2 wire address 1010001X (A2h), and is backward
compatible with the SFP Multi-Source Agreement. For further information, please refer to SFP
MSA and SFF-8472.
