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.

Class 1 Laser Safety per FDA/CDRH, (IEC) and EN 60825-1 laser safety regulations.
Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average power.
Unfiltered, 20-80%. Complies with FC 1G and 2G eye mask when filtered.
Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ and Δ DJ.
If measured with TJ-free data input signal. In actual application, output TJ will be given by
TJ OUT = DJ IN + Δ DJ + √(TJ IN - DJ IN)2 + (Δ TJ - Δ DJ)2

Connected directly to TX data input pins. AC coupling from pins into laser driver IC.
We recommend <600 mV for best EMI performance.
Or open circuit.
Into 100 ohm differential termination.

LOS is an open collector output. Should be pulled up with 4.7 k - 10 kohms on the host board. Normal operation is logic 0;
loss of signal is logic 1. Maximum pull-up voltage is 5.5 V.
Receiver sensitivity is compliant with a power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified
value applied through the recommended power supply filtering network.
Typical peak-to-peak jitter (=6*RMS width of Jitter).
Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ and Δ DJ.

Circuit ground is internally isolated from chassis ground.
Laser output disabled on TDIS >2.0 V or open, enabled on TDIS <0.8 V.
Should be pulled up with 4.7 k - 10 kohms on host board to a voltage between 2.0 V and 3.6 V.
MOD_DEF(0) pulls line low to indicate module is plugged in.
Transceivers operate at 1G and 2G Fibre Channel, and Gigabit Ethernet data rates and respective protocols without active
control.
LOS is open collector output. Should be pulled up with 4.7k – 10 kohms on host board to a voltage between 2.0 V and 3.6 V.
Logic 0 indicates normal operation; logic 1 indicates loss of signal.
