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

Singapore high-density designs should assess this item together with panel access, cable routing and the complete optical loss allowance. This configured-to-order trunk cable builds 12 to 144 OS2 9/125µm G.657.A1 fibers into a double-jacketed armored product 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. The double-jacket armored structure puts a helical steel tube around the fiber core; consequently, the backbone assembly carries the mechanical rating itself and the pathway will not by itself depend on the condition of the conduit.

MTP Elite performance and the loss budget

Because parallel-optic links chain multiple mated pairs, per-connector loss decides whether the path 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 leads end to end.

Polarity: Type A, Type B and Type C

MTP links must land transmit on receive, and the backbone assembly polarity is how that is engineered. Type An is straight-through, Type B is reversed, Type C is pair-flipped; the specified selection is set by the cassette and duplex cord plan at both connector interfaces. State the polarity method with the enquiry and the backbone assembly is built and labeled to match it.

Fiber counts from 12 to 144

Base-12 structure scales the corresponding 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 obtainable on ask for 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 version on long or conduit routes, and feed the backbone 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 the backbone assembly OD; consequently, plan sweeps rather than right-angle turns at every direction change.

Length choices and custom production

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

Quality assurance and factory testing

Every MTP termination is interferometry-checked for end-face geometry, and each 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. In Singapore facilities, this check should form part of the rack-access and acceptance review.

Quotation and Factory Support

Send the fiber count, connector gender per end, polarity type, jacket rating, pathway length and any breakout or pulling-eye specifications. The factory returns an arrangement plan with the quotation, and production starts once the plan is approved. Singapore and regional project orders can be reviewed for interface compatibility, packing details and delivery coordination.
