Overview
Small Form-Factor Pluggable (SFP) interfaces from MRV Communications provide flexible high speed links in a small
industry standard package. They deliver the deployment options and inventory control that network administrators
demand for growing networks.
SFPs are designed to Multi-Source Agreement (MSA) standards to ensure network equipment compatibility. They are a
perfect addition to MRV ‘s extensive lines of networking equipment.

TX Fault is an open collector output, which should be pulled up with a 4.7 k ~10 kΩ 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 0.8 V.
TX Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a
4.7 k ~10 kΩ 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
MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7 k ~ 10 kΩ 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 wires serial interface for serial ID
MOD-DEF 2 is the data line of two wires serial interface for serial ID
LOS is an open collector output, which should be pulled up with a 4.7 k ~ 10 kΩ resistor on the host board to a voltage
between 2.0 V and Vcc+0.3 V. Logic 0 indicates normal operation; logic 1 indicates loss of signal. In the low state, the output
will be pulled to less than 0.8 V.
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.
These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside
the module.
