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

For Tanzanian site work, correct product selection should be followed by careful transport, connector inspection and retention of the fiber records. This customized multi-fiber cable is a pre-terminated indoor unit built exactly to the setup the project specifies: connector styles and polish at each end, fiber count, jacket rating, breakout geometry and length are all specified at order time, and the finished trunk is optically tested leg by leg before dispatch. The flat build 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. Because the glass is the identical group used in the outside plant, the supplied assembly does not automatically become the weak point of the optical link 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 can damage both ferrules. Because this optical assembly is built with the polish specified at order time and tested as a complete trunk, the patch side matches the rack-mounted 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 installed 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.

Breakout geometry and why it matters

The breakout is where a trunk becomes usable. Equal-length legs suit a straight row of adjacent ports, whereas 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 version suits protected routing inside panels and cassettes. Selecting the geometry at order time means the supplied assembly arrives matching the hardware it serves.

Pre-terminated versus field termination

Terminating OS2 fiber in the field means a splicer, a tray location, consumables and the craft time to do it well - multiplied by every fiber in the installed trunk. A pre-terminated unit moves all of that work to the factory floor, where polishing, inspection and testing happen under controlled conditions. The installer who receives the supplied cable routes it, dresses the legs and mates the installed connectors; the connection is ready for light the identical hour. Since every field-terminated leg is another chance for a rework visit, for multi-fiber counts the saving cannot be regarded as linear but compounding,.

Planning a trunk route

A multi-fiber trunk is planned once and installed once; thus, the planning deserves the hour it takes. Measure the path through the actual containment, note the bend space at both connector ends, and decide which end gets pulled. State the pulling eye specification with the order if the path is long or congested. At the far end, leave the dressing slack the rack-mounted panel or cassette needs - the datasheet breakout lengths are the default, and other geometries are confirmed before fabrication.

Fiber Count Choices

This build is built with 2 Fibers per trunk, terminated and tested as a complete unit.

Custom Lengths as Standard Practice

Standard offerings cover the common routes: 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 10m (33ft), 15m (49ft), 20m (66ft), 30m (98ft), 25m (82ft), with customized length supplied beyond the list, including foot-based builds for projects specified in imperial units. Specifying the measured path length keeps the slack out of the tray and the strain off the installed connectors.

Factory Quality Control and 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. The supplied assembly ships with dust caps on every connector used and the test results supplied on order.

Purchase and Factory Support

Refer to this setup by fiber mode, fiber count, connector pair, breakout geometry and length when purchasing a quotation. For configurations outside the listed options - mixed connector families, jacket ratings, pulling eye, labeling or project packaging - send the specification with the request and the factory will ensure the build before fabrication. For Tanzanian deliveries, the order details should include any site identification needed by the installation team.
