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

For Pakistani procurement and engineering teams, the specification provides a practical basis for checking compatibility before production is requested. This configured-to-order trunk cable builds 12 to 144 OS2 9/125µm G.657.A1 fibers into a double-jacketed armored unit 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.

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. Because the double-jacket armored build puts a helical steel tube around the fiber core, the trunk assembly carries the mechanical rating itself and the path does not by itself depend on the condition of the conduit.

MTP Elite performance and the loss budget

Parallel-optic links chain many mated pairs, and therefore per-connector loss decides whether the link 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 patch cords end to end.

Polarity: Type A, Type B and Type C

MTP links must land transmit on receive, and the trunk assembly polarity is how that is engineered. Type An is straight-through, Type B is reversed, Type C is pair-flipped; the suitable option is a function of the cassette and duplex cord plan at the two interfaces. State the polarity method with the request and the trunk assembly is built and labeled to match it.

Fiber counts from 12 to 144

Base-12 build scales the identical 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 offered on specify for long or difficult pulls.

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 choice on long or conduit routes, and feed the trunk assembly rather than dragging it around bends. Because the 10mm minimum bend radius of the G.657.A1 core is generous, but the practical limit on site is set by the trunk assembly OD, plan sweeps rather than right-angle turns at each direction change.

Standard and custom length options

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

Test standards and quality control

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 Details and Factory Support

Send the fiber count, connector gender per end, polarity type, jacket rating, path length and any breakout or pulling-eye needs. The factory returns a setup diagram with the quotation, and production starts once the diagram is approved. For Pakistan, a clear port or maintenance schedule helps us confirm the correct factory-built configuration before supply.
