Custom MTP-12 Armored Trunk Cable, 12-144 Fibers, OS2

Malaysian upgrade projects can use this configuration where its interface and fiber map align with both the installed cabling and the new hardware. This configured-to-order trunk cable builds 12 to 144 OS2 9/125µm G.657.A1 fibers into a double-jacketed armored assembly terminated with US Conec MTP Elite connectors. It brings the backbone-class 0.35dB maximum insertion loss of elite MTP terminations to routes that need real mechanical protection: between buildings, through industrial plant, or anywhere a trunk must survive the pathway instead of being protected by it. Malaysian upgrade teams can use this detail to compare the new assembly with the installed cabling records.

Specifications

Armored trunk cabling for backbone links

Backbone trunks cross the most hostile pathways in a facility: riser shafts shared with power, inter-building conduits, plant rooms with moving machinery. The double-jacket armored construction puts a helical steel tube around the fiber core, meaning that this trunk assembly carries the mechanical rating itself and the route is not designed to depend on the condition of the conduit.

MTP Elite performance and the loss budget

Parallel-optic links chain several mated pairs, meaning that per-connector loss decides whether the channel closes. MTP Elite ferrules hold insertion loss to 0.35dB maximum with 0.15dB typical, roughly half the allowance of standard MTP terminations, which buys real headroom when the design stacks a trunk, two cassettes and patch cords end to end.

Polarity: Type A, Type B and Type C

MTP links must land transmit on receive, and this trunk assembly polarity is how that is engineered. Type An is straight-through, Type B is reversed, Type C is pair-flipped; the intended choice varies with the cassette and duplex cord plan at the two terminations. State the polarity method with the inquiry and this trunk assembly is built and labeled to match it.

Fiber counts from 12 to 144

Base-12 construction scales the same trunk design from a single 12-fiber tube to 144 fibers in a 14.2mm double-jacketed build. Breakout legs are 2.0mm at 0.84m as standard, with pulling eyes and alternative leg arrangements available on request for long or difficult pulls. Malaysian upgrade teams can use this detail to compare the new assembly with the installed cabling records.

Pulling and installation practices

Armored trunks pull like a cable, not like a patch cord: respect the 200N long-term limit, use the pulling eye option on long or conduit routes, and feed this trunk assembly rather than dragging it around bends. The 10mm minimum bend radius of the G.657.A1 core is generous, but the practical limit on site is set by this trunk assembly OD, meaning that plan sweeps rather than right-angle turns at each direction change.

Available lengths and custom orders

Trunks are built to the route: typical orders run from 1m (3ft) hardware-room links to 30m (98ft) and well beyond for inter-building pulls. Give the measured route with allowance for vertical drops and service loops, and the factory confirms the build and packing for the stated length.

Testing and inspection practice

Each MTP termination is interferometry-checked for end-face geometry, and every finished trunk is 100% insertion loss and return loss tested on all fibers, with results shipped against the serial number. The 0.35dB maximum and 65dB return figures are verified per mated pair, and the armor and jacket are inspected over the full trunk length.

Ordering and Customization Support

Send the fiber count, connector gender per end, polarity type, jacket rating, route length and any breakout or pulling-eye requirements. The factory returns a configuration drawing with the quotation, and production starts once the drawing is approved. Malaysian upgrade teams can use this detail to compare the new assembly with the installed cabling records. For Malaysian upgrades, our team can compare the requested build with the existing environment before production begins.
