SpiderSDI Pro - Broadcast Camera EFP Fiber Transmission System 12G-SDI - XLR Audio - TALLY - Intercom - Gig Ethernet

 

An EFP (Electronic Field Production) fiber transmission system is the optimal technology used in broadcasting and live event production to transmit video, audio, and data signals over long distances using fiber optic cables. The most prominant examples of these being used are inside ball parks and racetracks, for superior quality broadcasting up to 12G-SDI that includes intercom for techincal communications and directions given to camera operators. Included with this functionality is the ability to carry tally, audio, ethernet, XLR, and bidirectional SDI which creates a single strand solution using CWDM to execute at the highest echelons of resolution and AV operability and distribution. Consider an NFL stadium where numerous on field cameras transmit Live feeds back to the production trailor outside the stadium; here the producer can call out to different camera operators by number with instructions, change the view of the Live broadcast, and operate with audio and high def video in realtime while utilizing the SDI, intercom, ethernet and tally to help control, instruct, and communicate with his operators inside the stadium while he's at the production studio outside in the form of a trailor generally. The same situation can be utilized in various sports, racing, live productions of theatre, house of worship, and concerts. 

EFP systems are commonly used in situations where traditional copper-based cabling is impractical due to distance limitations, signal degradation, or electromagnetic interference. Futhermore, the EFP fiber transmission systems offer several advantages over traditional cabling methods, including higher bandwidth, longer transmission distances, and immunity to electromagnetic interference. 
Based on most user experiences we hear about from operators in the field, the transmitter of the equipment is compact with dims of 112x159x70mm and just two pounds, equipped with a 1/4 hot shoe, V-port hanging board, which can supply power to the fiber optic converter and the camera or other photographic equipment through the V-port mobile power supply, which is convenient for use in outdoor environments for operation. The receiver is a 1RU rack mount box, which is convenient for users to facilitate unified management and power supply in the field such as the broadcast truck or the headend room; the internal circuit part of the equipment uses all-digital circuits, creating a stable, low power consumption, and is easy to install and maintain. The power supply system uses a LEMO physical interface 6-pin, wide voltage design (9~24V), support V-port mobile power supply, which can ensure flexible and stable power supply in the field.
