FEATURE CABLES & CONNECTORS
professional sports venues, mobile production units, as well as production and post-production facilities. Many facilities require unique cable infrastructure so Diversified has an appreciation of the advantages fibre optic cable offers for greater durability and ease of installation. OCC’s six- and 12-strand DX Series indoor/outdoor distribution cables are often used as a solution for many challenging installations. The OCC cable has the inclusion
of a rigid central strength member, which is of vital importance in permanent installations. Fibre cable is pulled through conduit and is often exposed to ten times the tension that it would normally incur. On one project, Justin Guzman,
Diversified’s project engineer, and his team had a situation where the cabling in the building needed to be plenum rated. However, the final 200 feet of cable was in an underground conduit that was subject to flood-out. “For our copper cable types we had to
run both an underground-rated cable and a plenum-rated cable,” Guzman explains. “Where the conduits emerged from underground we spliced them together. For the fibre, we were able to utilise the OCC DX indoor/outdoor cable series, which met the criteria for water blocking and plenum rating. This enabled us to forgo a lot of additional fibre splicing and management.”

Guzman added that the unique
capabilities of OCC cable met both criteria and saved labour and unnecessary splicing.
EXPEDITING AV APPLICATIONS Companies large and small are dependent on using AV applications for critical services ranging from training to teleconferencing. Many of these applications require the integration of a variety of different AV devices within facilities at many geographic points. This often requires employing installation staff with skillsets such as crimping and soldering, particularly when various types of AV gear are not configured to work together. When the companies transition AV
facilities from analogue to digital, it requires a new type of cabling to carry digital signals. This means a different type of installation technician is needed - IT integrators. These technicians have the tools and skillset required to install fibre optic cable to transport packetised data, alongside cable to power the equipment. Performing this type of installation involves pulling both types of cable, cutting it to length, terminating it and then plugging it into AV gear. However, if this process can be
simplified, installation becomes more efficient and less expensive. In some past instances, OCC has provided AV users with hybrid cables that included both
the fibre optic and power cable all in one. Additionally, OCC has provided the cabling in kit form, with each kit containing pre-terminated, pre-cut cabling for connecting specific equipment housed in each of multiple (sometimes hundreds of) AV rooms. Each ‘plug and play’ hybrid cable is labelled with a specific part number and each cable box would be designated for a specific AV location, such as a conference room, lab or command centre. This ‘kitting’ of the plug and play cable for specific AV room locations has allowed standard installation contractors to handle the installation tasks rather than requiring the expertise of IT or AV contractors. This can result in a reduction in installation time of as much as 25 per cent as well as saving significant money on labour. Additional savings on the plug and play
cable can also be realised when it is pre- terminated at the factory, which means it has also been pre-tested by factory technicians. This also provides a greater degree of reliability and reduces the time to certify the installed system. OCC’s line of SMPTE 311-compliant
cables rounds up the company’s cable offerings, providing a range of products for a variety of audio, video and broadcast applications across different industries.
