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.

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 ohms differential termination.
Unfiltered, 20 – 80 %
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 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 ΔDJ. If measured with TJ free data input
signal. In actual application, output TJ will be given by:
TJOUT = DJIN + ΔDJ + √ (TJIN - DJIN)2 + (ΔTJ - ΔDJ)2

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.
For Rate Selectable Version Only: In accordance with SFF Committee SFF-8079 Draft, Rev.1.6, Table 3. Note that rate select can also be set
through 2-wire bus in accordance with SFF-8472 at Bit 3, Byte 110, Address A2h (note: writing ‘1’ selects full bandwidth operation). Rate select
is the logic OR of the input state of Rate Select Pin and 2-wire bus. Non Rate Selectable version can operate at 1G, 2G, 4G Fibre Channel
independent of rate select pin setting.
LOS is open collector output. Should be pulled up with 4.7 k – 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.
