Overview
MRV’s digital video SFP-TMDV3G is designed to affordably transmit SDI, HD-SDI, 3G-SDI, or DVB digital video component
signals over fiber using standard optical transceivers. Compatible with any optical transport system – WDM platforms,
optical/electrical cross-connects, etc. – the unidirectional digital video SFPs from MRV open a new world of costeffective digital video deployment options:
- Link extension over new or existing fiber plant
- Wave division multiplexing (CWDM and DWDM)
- Link redundancy for mission critical applications
- Video distribution and multicasting
... and more!
SDI HD-SDI, 3G-SDI, and DVB are the basic standards used to transport serial component digital video data on single
coaxial cable. Coaxial cable limits the link range to 350 meters between the signal source and destination for standard
definition video, 140 meters for high definition, and 100 meters for 3G video. These distances are designed for intrabuilding or small campus networks.
However, the advent of geographically dispersed studio campuses requires more digital video data to travel across
the sophisticated optical infrastructure of the metro and inter-metro network. Links of 100 kilometers or more and
the use of WDM technology are increasingly common. MRV’s digital video SFPs easily merge digital video traffic onto
these optical transport networks.

Datasheet
MRV’s digital video SFPs are designed to carry digital video signals (see specific protocols in the datasheet).
Pathological signals (long strings of sequential zeros or sequential ones) require additional processing.
The SFP-TMDV3G-RX is a coaxial receiver designed to support digital video signals as defined by the SDI, HD-SDI,
3G-SDI, or DVB standards. It recognizes the digital video stream and generates a data signal that is compatible with
these optical transport systems supporting the digital video data rates.
The signal passes through the receiving module to an MSA-standard optical transceiver that transports it over a fiber
optic link. At the far end of the optical link, the signal is received by another MSA-standard optical transceiver and
passed to the SFP-TMDV3G-TX.
The SFP-TMDV3G-TX, in turn, processes the data signal and sends the resulting digital video stream to the receiving
digital video device, once again over a coaxial cable.

Data Direction
The SFP-TMDV3G-RX, here mounted in a
Fiber Driver EM316DMR3G-3R, receives a
unidirectional SDI signal from a
connected video device. The SDI signal is
then transmitted over fiber via a
standard SFP optical transceiver.

The optical SFP transceiver on the other
side of the fiber link receives the SDI data
signal. The EM316DMR3G-3R (Dual Multirate Transponder) passes the SDI signal
to the SFP-TMDV3G-TX, and delivers it to
the end point video device.

only the small subset of the information described
in the MSA that applies to them. This subset of
information is described in the “EEPROM and Interface
Details“ section.
