MRV’s Digital Video SFPs Receive U.S. Patent

MRV communications, provider of optical communication solutions, has announced that its digital video SFP (Small Form-factor Pluggable) interface series has received the U.S. patent.

The SFP interfaces are mainly used for transmitting HD-SDI (high-definition serial digital interface) and SDI (serial digital interface) video over any type of fiber-optic network. Transmission of the HD-SDI and SDI videos is made possible with the help of an encoding algorithm in the SFP interfaces. The algorithm is mainly based on the EG-34 industry specifications.

Earlier, the SDI and HD-SDI videos were normally transmitted over coaxial copper cables for limited distances. A separate fiber-optic cable network and unique transmission devices are required to transmit the videos over long distances.

A separate network is required because the HD-SDI and SDI videos’ data-scrambling algorithm is not compatible with current generation of optical devices. MRV’s SFP enables the data to be transferred over the fiber optic network by utilizing standard optical transport devices, thereby enhancing the flexibility of the network and reducing expenditures.
