Where multi-way fibre cables, fitted with Opticalcon Dual or Opticalcon Quad connectors, are used to provide a point-to-point link, these break-out boxes split the two or four channels to a variety of other formats, including Duplex LC, SC and ST connectors, depending on model. The connectors are mounted in a rugged, extruded enclosure, suitable for use in broadcasting and live-event environments. Both multi-mode and single-mode types are offered.
These designs are assembled to order, using stocked modules, in short time scales. Alternative configurations, such as mixed LC, SC and ST connections can also be accommodated, subject to quotation.
The enclosures are black anodised aluminium, with aluminium alloy end-plates and reverse printed labels; graphics show internal configuration. ABS bezels fit over the ends giving good protection to the box. All connectors are fitted on the end-plates, within the bezels. The enclosures are fitted with an black, aluminium plate, cut to provide a carrying handle, which can be used to restrain the box, as well as two 'key-holes' for mounting screws, for use where a more permanent fixing is required. The 'key-holes' match rack-strip spacing. Enclosure dimensions: 160 x 110 x 47(l x w x h)mm, over the bezels. The handle plate protrudes 33mm from the enclosure.
The Opticalcon connectors are designed around the duplex LC optical connector, housed in a rugged latching body. Opticalcon Duo types, only, will accept either Opticalcon Duo assemblies or standard LC connectors at the front face. Opticalcon Quad will only mate with Opticalcon Quad cable assemblies at the front. Fibres within the chassis connectors are protected from dirt, when un-mated, by integral, automatic, sealing-shutters with silicone gaskets, which lift when the connectors are mated. The shutters also block laser emission, should a source be left switched on inadvertently. These boxes use Opticalcon Duo NO2-4FDW-A (46-4002) and Opticalcon Quad NO4FDW-A (46-4032) types.
LC duplex, SC simplex and ST connections use Senko professional fibre through-couplers. These have tight-tolerance housings and precision ferrules to ensure exceptionally accurate connector alignment and fibre-face contact. This ensures lower loss and greater reliability than commercial grade types. The LC and SC types have an internal 'light shutter' which although not an environmental seal, does offer some protection from large particle ingress and protects against laser spillage from unmated 'live' ports. All couplers are furnished with tethered dust-caps.
Colour coding: The Opticalcon connectors are fitted with gaskets, colour-coded to indicate whether the box is a single-mode or multi-mode type. LC and SC connectors are also colour coded.
