Small Form-factor Pluggable (SFP) Optical Module Cartridges (12G Video)

The Small Form-factor Pluggable (SFP) optical module cartridges for video are small, hot-pluggable devices used to provide fiber connectivity to 12G/3G/HD/SD SDI products from either a Densité frame (they can be used with any 12G video card that has a rear module with an "F" name suffix (i.e., HDA-3961-3SRP-HF), irrelevant of which Densité frame is hosting the card), IQ Modular 12G SDI card such as the IQSDA4100-1B4, IQSDA4200-1B4 and the KudosPro UHD-1200.
