Compatible with any optical transport system – WDM platforms, digital cross-connects, etc. – these unidirectional digital video SFPs open a new world of cost-effective 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/multicasting ... and more! SDI, HD-SDI, and DVB are the basic standards employed in the transport of serial component digital video data on single coaxial cable. Using coaxial cable between the signal source and destination limits the link range to 350 meters, or to 140 meters for high definition. This distance is generally adequate for intra-building or small campus networks. However, the advent of geographically dispersed studio campuses requires more and 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. Merging digital video traffic onto these optical transport networks is further complicated by the encoding methods for these protocols. 1 Datasheet Digital video signaling includes a data scrambling algorithm for SDI and HD-SDI that is not easily transported over a standard optical transport system. This algorithm can produce a signal pattern that causes an error in standard optical systems. With a certain pattern in the video data, the scrambling algorithm can generate a pathological signal containing a series of up to 19 bits of the same polarity. These pathological patterns are not transportable over optical transport systems that employ “off the shelf” optical components. These components are generally designed to use an AC-balanced signal with a duty cycle of approximately 50%. That allows the optical transceiver to properly modulate the laser control loop (transmit side) and lock (PLL circuitry) its receiver. Until now, the industry has addressed this problem by providing optical components specifically designed for use with the pathological signaling of digital video: typically DC-coupled optical transceivers. This approach requires customized transceivers for each combination of distance, wavelength, and fiber type (multi-mode or single-mode) used. Specialized solutions must also be built for WDM applications. Such designs are purely proprietary, and therefore tend to be expensive. Unfortunately, DC-coupled transceivers generally have up to 8 dB lower receive sensitivity than AC-coupled components, and they cannot be amplified in a DWDM application. This sensitivity loss reduces link range by as much as 35 kilometers. In contrast to the situation with digital video specialty components, the optical Multi-Source Agreement (MSA) has led to a ready supply of inexpensive optical interfaces for most applications. However, the specific digital video solutions cannot use this huge selection of standard and affordable optical components. The general-purpose type of optical transport platform (multi-rate/multi-protocol transponder or repeater) simply cannot handle digital video. Video Extension Over Fiber Post Production Facility Film Studio Data Direction Digital Video over Coax (0-350 m) Data Direction SDI SFP Digital Video over Coax (0-350 m) FO SFP FO SFP Fiber Optic SDI Link 0-120+ km Data Direction The SFP-CXASI-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-CXASI-TX, and delivers it to the end point video device. 2 Datasheet HD-SDI: The new MRV digital video SFPs offer a direct and affordable solution to the problems of digital video optical transport. They allow the transport of SDI, HD-SDI, or DVB ASI component video signals over any optical transport system that employs MSA standard optical transceivers. The SFPxMRHDSDI-RXR SFP is a unidirectional multi-rate coaxial receiver designed to support digital video signals as defined by the SDI and HD-SDI standards. It takes the digital video stream and generates a data signal that is compatible with any standard optical transport system. The signal is passed through the system to an MSA standard optical transceiver, and transports it over a fiber optic network. At the end of the transmission link, the signal is received by another MSA standard transceiver and passed to the SFPxMRHDSDI-TXR. The SFPxMRHDSDI-TXR, in turn, processes the data signal and sends the resulting digital video stream to the receiving digital video device. The HDSDI products support main video systems (NTSC and PAL) currently in use. The multi-rate digital video SFP supports either NTSC or PAL standards for standard definition and high definition. CXDV: The CXDV SFPs support SD digital video at 270 Mbps, but they do not support 1.5 Gbps. CXASI: The SFP-CXASI-xxR SFP is designed to support digital video signals that do not contain pathological patterns.
