    Overview:

    Multi-Rate Digital Video SFP
    SFP-TMDV
    F-TONE’s digital video SFP-TMDV is designed to af ordably transmit SDI, HD-SDI, or DVB digital video component signals 
    over i ber using standard optical transceivers. Compatible with any optical transport system – WDM platforms, optical/
    electrical cross-connects, etc. –  the unidirectional digital video SFPs from F-TONE open a new world of cost-ef ective 
    digital video deployment options:
     - Link extension over new or existing i ber 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 
    dei nition video, and to 140 meters for high dei nition. 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.  F-TONE’s digital video SFPs easily merge digital video trai  c onto 
    these optical transport networks.
     
    The F-TONE 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 i ber optic transceivers require additional processing before 
    transmission through a standard optical transceiver. However, the SFP3MRHDSDI and SFP5MRHDSDI digital video 
    SFP families from F-TONE 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 dei ned 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 i ber 
    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.
