Optical Video SFP Modules

Overview

The FiberPlex Technologies Video SFP (Small Form Factor Pluggable) optical modules are designed to transmit optical serial digital signals as defined in SMPTE 297-2006. The SFP modules are high performance, and cost effective supporting a host of data rates and distances. They are RoHS compliant and lead-free. These optical modules are designed specifically for error-free performance in the presence of SDI pathological patterns across their entire range of supported data rates. The FiberPlex Video Optimized SFPs have a very high sensitivity and expanded optical power output making them highly reliable in even the most complex of cable plant applications. While they are optimized for maximum video performance, they can also be used for standard data and telecom applications.  For data and telecom only applications see our line of Data SFP Modules.

Why Video Optimization?

The Society of Motion Picture and Television Engineers, or SMPTE, is a leader in the development of standards for film, television, and other video. The Serial Digital Interface or SDI, was standardized by SMPTE for broadcast quality digital video transmission. Other standards evolved from this original standard, defining Enhanced, High-definition (HD), 3G-SDI (1080p) and Ultra High-definition (UHD), or 4K video (2160p).

To help ensure error-free transmission, the standards include a data scrambler / descrambler to create a high density of transitions in the serial data, making it easier for the receiver to maintain timing. As a result, there are certain combinations of scrambler state and the next data bits to be scrambled that result in a sequence of up to twenty consecutive ones or zeros. These sequences are referred to as pathological conditions, and are present in specific shades of pink or grey. These pathological conditions may create errors in transmission through typical AC coupled optics, or any other AC coupled interface. Video Enhanced or SMPTE Compliant optics are designed to accept these pathological conditions, allowing the longer sequences of ones or zeros to pass without error.

A Large Selection of Optics

The FiberPlex Technologies line of Video Optimized SFP Modules support a broad range data rates, wavelengths (λ) and power configurations providing maximum flexibility. The SFPs are available in dual fiber tranceivers (TX and RX) as well as dual transmit and dual receive versions. The selection table in the Video SFP datasheet lists many of the popular options and the corresponding FiberPlex SFP part number.
