Customized OS2 Indoor Multi-Fiber Flat Cable, LC/SC/FC/ST/LSH, 1.6mm Breakout

Selection starts with the actual optical interface and ends with verification of the delivered configuration. This custom-built multi-fiber cable is a pre-terminated indoor product built exactly to the arrangement the project specifies: connector styles and polish at each end, fiber count, jacket rating, breakout geometry and length are all chosen at order time, and the finished trunk is optically tested leg by leg before dispatch. The flat structure packs the fibers in a low-profile ribbon-like trunk with 1.6mm breakout legs, a geometry that lies flat under floor coverings and in shallow channels where a round cable will not fit.

A pre-terminated OS2 trunk carries the links that leave the room: riser spans between floors, campus backbones between buildings and every wavelength-multiplexed service in between. The glass is the same class used in the outside plant; as a result, this manufactured assembly does not on its own become the weak point of the loss-budget calculation. At 1310 and 1550nm the attenuation stays a fraction of a decibel per kilometer, and each factory-polished connector adds less than 0.3dB when the end faces are clean and seated.

Single-mode plants are unforgiving about polish mismatches: a UPC leg mated into an APC port destroys the return loss and might damage both ferrules. The supplied assembly is built with the polish specified at order time and tested as an entire trunk; as a result, the patch side matches the relevant panel side exactly. When documentation is unclear, the boot color tells the truth: green for APC, blue for UPC.

A pre-terminated trunk is only as good as its journey through the pathway. The optional pulling eye protects the connectorized end during the pull and keeps the relevant trunk from twisting, which matters on long riser runs and congested trays. The installation load rating on the datasheet is the number the pulling rope should respect, not the weight of the reel.

The breakout is where a trunk becomes usable. Whereas staggered legs reach a column of ports without slack piling up at one end, equal-length legs suit a straight row of adjacent ports. The 2.0mm legs survive patching-field handling; the 0.9mm model suits protected routing inside panels and cassettes. Specifying the geometry at order time means this manufactured assembly arrives matching the hardware it serves.

Terminating OS2 fiber in the field means a splicer, a tray slot, consumables and the craft time to do it well - multiplied by every fiber in the relevant trunk. A pre-terminated product moves all of that work to the factory floor, where polishing, inspection and testing happen under controlled conditions. The installer who receives the relevant cable routes it, dresses the legs and mates the connection interfaces; the channel is ready for light the same hour. For multi-fiber counts the saving is not equivalent to linear but compounding, as every field-terminated leg is a further chance for a rework visit.

A multi-fiber trunk is planned once and existing once; as a result, the planning deserves the hour it takes. Measure the pathway through the actual containment, note the bend space at the two connection points, and decide which end gets pulled. State the pulling eye need with the order if the pathway is long or congested. At the far end, leave the dressing slack the relevant panel or cassette needs - the datasheet breakout lengths are the default, and other geometries are confirmed before production is released.

This structure is built with 2 Fibers per trunk, terminated and tested as an entire product.

Regular length versions cover the common routes: 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 10m (33ft), 15m (49ft), 20m (66ft), 30m (98ft), 25m (82ft), with custom-built length provided beyond the list, including foot-based builds for projects specified in imperial units. Specifying the measured pathway length keeps the slack out of the tray and the strain off the connection interfaces.

Every trunk is terminated with precision zirconia ferrule connectors and optically tested leg by leg before packing: insertion loss and return loss are verified on each fiber, and end-face geometry is inspected for consistent physical contact. This manufactured assembly ships with dust caps on each relevant connector and the test results provided on ask for.

Refer to this arrangement by fiber mode, fiber count, connector pair, breakout geometry and length when requisitioning a quotation. For configurations outside the listed options - mixed connector families, jacket ratings, pulling eye, marking or project packaging - send the need with the inquiry and the factory will cross-check the build before production is released. Huihong Technologies can review the selection and customization details before confirming supply.
