MRV Communications, an innovator in the field of IT infrastructure management solutions and optical communications, has disclosed that their Digital Video small form-factor pluggable (SFP) interfaces have acquired a U.S. patent No. 7,688,231. The SFP is mainly used to transport serial digital interfaces (SDI) and high definition (HD-SDI) video, through a fiber-optic series.
The SFP interfaces employ a program based on EG-34 industry stipulations, which permits broadcast of HD-SDI or digital video SDI over fiber-optics, with the help of standard and ready-made optical transport devices. In the past, it was done using copper coaxial cables, over limited distances, such as a few hundred yards, and greater distances could be covered by using a network dedicated for this task along with fiber-optic cables, and transmission devices that needed to be constructed specifically for this purpose. However, the SFP transmits the data over fiber cables, using the regular equipment, thereby leading to decreased costs and superior network flexibility.
These SFPs are accessible for 270 Mbps SDI, and for both the 1.4835 Gbps NTSC and 1.485 Gbps PAL/SECAM standards of the HD-SDI video, and additionally for 270 Mbps DVB-ASI. In addition, MRV provides coax SFPs for DVB-ASI (270Mbps). MRV is able to deliver a potent range of HD networking systems by integrating SFP with MRV’s other products such as LambdaDriver, TereScope, Media Cross Connect and Fiber Driver
According to MRV’s CEO, Dilip Singh, receiving the patent was of great significance to the company, as it would reinforce the company’s intellectual property collection, and also promote its position in the video network market. Market research has suggested that the video transport sector would touch $440 million, by the year 2014.
