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.
Visit the MRV website at www.mrv.com or contact your nearest authorized MRV Communications dealer for more

Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
Also specified to meet curves in FC-PI 13.0 Figures 18 and 19, which allow trade-off between wavelength, spectral width and
OMA.
Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average power.
Unfiltered, 20-80%. Complies with IEEE 802.3 (GbE)m FC 1G and 2G eye masks when filtered.
Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ and Δ DJ.
Measured with conformance signals defined in FC-PI 13.0 specifications.
Measured with PRBS 27-1 at 10-12 BER.

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.
