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

Singapore high-density designs should assess this item together with panel access, cable routing and the complete optical loss allowance. This custom 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 selected 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.

Specifications

Single-mode trunks for building and campus backbones

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 corresponding class used in the outside plant; consequently, this optical assembly will not by itself become the weak point of the link loss budget. 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.

Connector and polish discipline on single-mode links

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

Pulling eye and installation practice

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 backbone assembly from twisting, which matters on long riser runs and congested trays. The deployment load rating on the datasheet is the number the pulling rope should respect, not the weight of the reel.

Breakout geometry and why it matters

The breakout is where a trunk becomes usable. Equal-length legs suit a straight row of adjacent ports; concurrently, staggered legs reach a column of ports without slack piling up at one end. 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 optical assembly arrives matching the hardware it serves.

Pre-terminated versus field termination

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 backbone assembly. 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 this optical cable routes it, dresses the legs and mates these optical interfaces; the channel is ready for light the corresponding hour. For multi-fiber counts the saving must not be treated as linear but compounding, for the reason that every field-terminated leg is another chance for a rework visit.

Planning a trunk route

Because a multi-fiber trunk is planned once and existing once, the planning deserves the hour it takes. Measure the pathway through the actual containment, note the bend space at both connector interfaces, and decide which end gets pulled. State the pulling eye requirement with the order if the pathway is long or congested. At the far end, leave the dressing slack the patch panel or cassette needs - the datasheet breakout lengths are the default, and other geometries are confirmed before manufacturing begins.

Available Fiber Counts

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

Length Choices and Custom Production

Standard cable lengths cover the common routes: 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 10m (33ft), 15m (49ft), 20m (66ft), 30m (98ft), 25m (82ft), with custom length obtainable 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 these optical interfaces.

Quality Assurance and Factory Testing

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 optical assembly ships with dust caps on each optical connector and the test results obtainable on ask for.

Quotation and Factory Support

Refer to this arrangement by fiber mode, fiber count, connector pair, breakout geometry and length during the request for a quotation. For configurations outside the listed options - mixed connector families, jacket ratings, pulling eye, marking or project packaging - send the requirement with the enquiry and the factory will review the build before manufacturing begins. Singapore and regional project orders can be reviewed for interface compatibility, packing details and delivery coordination.
