Connecting With The Essential Links
If you work in a typical broadcast production, post-production or playout facility, then you will probably have seen the snake pits. This is not a reference to squabbling workmates but to the thickly populated cable ducts that connect much of the electronic kit in various locations to form a cohesive system. In the old days, these ducts carried analogue video and audio on their respective lengths of copper cables. The transition to digital operation saw the rise of serial digital networks carrying multiplexed video, audio and metadata along a single copper cable or optical fibre (and bundles thereof). More recently still, cabled IP networking has become a popular and easily expandable basis for interconnecting disparate equipment. So what’s new? One thing is very new indeed and potentially very hot but I will leave that to last. AFP’s ‘Secure RJ45 connectivity solution’ (that is its name) is designed to prevent unauthorised or inadvertent changes to cabling networks in critical applications. It can be retro-fitted to nearly all industry-standard RJ ports in both network equipment and patch panels. It is available in CAT6 Slim-line and CAT6A performance configurations and complies to TIA-568-C.2 standards. Locking secure RJ connectors are used; these can only be unplugged with matching colour-keyed extraction tools. These tools also automatically de-latch the RJ connectors from the ports, limiting disturbance and damage to adjacent connector channels in dense applications. The SRJ connector is supplied with a transparent polymer housing allowing the operator to view the status LEDs on active electronic equipment. Access to empty or unassigned ports can be prevented with the use of keyed colour-coded SRJ Port Blockers. The SRJ solution complements the Secure LC fibre solution also available for optical networking from AFP.

The first link is the most vital in any production chain and every facility relies on miles of hidden cabling. David Kirk lifts the lid on those trunking cable runs…

Camera Corps BC550

Argosy’s Fibre Optic Cleaning Tool is designed to clean SMPTE and traditional fibre-optic telco connectors on cables and those located in panel adaptors. It uses a dry cleaning strand that wipes and lifts any dirt or residue away without the need for solvents. Each tool is claimed to allow a minimum of 525 cleans. The tool also allows users to clean connectors without the need to remove alignment ferrules. Asheridge distributes Contech Chemshrink which gives protection from corrosion, vibration, temperature cycling, connector loosening and tampering. Chemshrink products provide three points of contact, completely sealing the cable, F-connector, and the tap spigot, creating a rubberised encapsulation. Belden has announced a new line of industrial grade Cat 6 cord sets warranted to provide reliable data transmission for Gigabit industrial Ethernet implementations. Made with Belden DataTuff industrial Ethernet cables, the Cat 6 cord sets are made with RJ45 plugs, available in shielded and unshielded versions and suitable for IP20 or IP67 applications. The IP20 cord sets are terminated with RJ45 connectors and are fully compatible with suitable Hirschmann and GarrettCom networking products as well as other industry networking

devices. Camera Corps’ BC550 compact fibre-optic link is designed for use with HD remote camera heads such as the Q-Ball and Q-Ball Pre-Set. It consists of separate transmitter and receiver modules, each housed in an impact-resistant and weatherproof metal case. Dual-fibre carries HD/SD-SDI from the camera to the control position plus a reverse direction channel which communicates data from the controller to the camera. Control data is encoded onto an audio carrier using the proven technology deployed across Camera Corps’ entire range of remote camera control systems. C o m p a c t form-factor LC connectors allow fast attachment of dual singlemode optical fibres to the link. Power can be sourced from the same 12 volt supply as the Q-Ball remote pan/tilt/ zoom camera. Equalisation and re-clocking within the integral Fischer Minimax

video processor permit long cables to be used between the transmitter and receiver. A red LED warning light on the front panel illuminates in the event of signal loss. Video output is via a standard 75 ohm BNC connector. The BC550Rx receiver module has a high impedance data input port allowing multiple BC550Tx transmitters to feed it in parallel. Five interface boxes can be fed from a single fibre receiver. XLR link and XLR4 splitter cables are available for use with the Q-Ball interface. The BC550Tx and BC550
