Optical Communications Systems™ Datasheet Multi-Rate Digital Video SFP SFP-TMDV Highlights Digital video signals over fiber optic links Wide protocol support with 143 Mbps to 1.485 Gbps data rates (output data rate equals input data rate) HD-SDI - SMPTE 292M (1.4835/1.485 Gbps) SDI - SMPTE 259M (143/177/270/360 Mbps) - SMPTE 344M (540 Mbps) DVB ASI (270 Mbps) 75 ohm coaxial input/output with standard BNC connectors Plug-n-Play operation SFP MSA (as applicable) Advantages Allows uncompressed digital video component signal transport over any standard optical transport system Allows standard optical transceivers (MSA compliance) Supports digital video links over fiber optic cabling Overview MRV’s digital video SFP-TMDV is designed to affordably transmit SDI, HD-SDI, or DVB digital video component signals over fiber using standard optical transceivers. Compatible with any optical transport system – WDM platforms, optical/ electrical cross-connects, etc. – the unidirectional digital video SFPs from MRV 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 and multicasting ... and more! SDI HD-SDI, and DVB are the basic standards used to transport serial component digital video data on single coaxial cable. Coaxial cable limits the link range to 350 meters between the signal source and destination for standard definition video, and 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 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. MRV’s digital video SFPs easily merge digital video traffic onto these optical transport networks. 1 Optical Communications Systems™ Datasheet The MRV SFP-TMDV modules are designed to carry most generic digital video signals, which inherently have a duty cycle of approximately 50%. Long strings of repeating 0s or 1s in a signal cause the duty cycle to range far from 50%. These pathological digital video patterns that stress fiber optic transceivers require additional processing before transmission through a standard optical transceiver. However, the SFP3MRHDSDI and SFP5MRHDSDI digital video SFP families from MRV handle these pathological signals in a standard host module without extra processing. The SFP-TMDV-RX is a coaxial receiver designed to support digital video signals as defined by the SDI, HD-SDI, or DVB standards. It recognizes the digital video stream and generates a data signal that is compatible with these optical transport systems supporting the digital video data rates. The signal passes through the receiving module to an MSA-standard optical transceiver that transports it over a fiber optic link. At the far end of the optical link, the signal is received by another MSA-standard optical transceiver and passed to the SFP-TMDV-TX. The SFP-TMDV-TX, in turn, processes the data signal and sends the resulting digital video stream to the receiving digital video device, once again over a coaxial cable.

The SDI signal is then transmitted over fiber via a standard SFP optical transceiver. * Coax Protocol Length SD (270 Mbps) 350 m HD (1.485 Gbps) 140 m 2 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-TMDV-TX, and delivers it to the end point video device.
