2.125Gbps 15500nm SFP with monitoring function
Preliminary Datasheet Dec. 20, 2003
Product Description
FTM-5120C-L80x is compliant with the specifications set forth in the SFP MSA. It is designed for
use in Fibre Channel applications both at 1.0625Gbps and 2.125Gbps. This transceiver also meets
the requirements of IEEE 802.3 Gigabit Ethernet standard and can be used in Gigabit Ethernet
network equipments.
FTM-5120C-L80x incorporates a highly reliable 1550nm DFB laser in its transmitter section. Its
pluggable architecture allows the module to be installed into MSA standard SFP ports at any time
even with the host equipment operating online. This facilitates the rapid configuration of
equipment to meet the user’s needs precisely: reducing inventory costs and network downtime.
Compared with traditional transceivers, the size of the Small Form Factor package enables higher
port densities.
Spring latch For High Density Application
FTM-5120C-L80x features a spring latch that allows user to easily remove the SFP transceiver by
hand in high-density application.
Monitoring Interface Compliant With SFF-8472
FTM-5120C-L80x 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.

Figure 5, Pin View
FTM-5120C-L80x has three stages of contact sequencing during insertion. The ground make
contact at first in sequence stage 1, then followed by power supply in sequence stage 2, finally,
signal lines engage in sequence stage 3. Conversely, when the module is plugged out from the
host system, signal lines disengage firstly, then power supply and ground.
It is the responsibility of the system integrator to assure that no thermal, energy, or voltage
hazard exists during the hot-plug-unplug sequence. It is also the responsibility of the system
integrator and end-user to minimize static electricity and the probability of ESD events by careful
design.

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):
(>0.8V, <2.0V):
High (2.0~3.465V):

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.
