Customized OS2 Indoor Multi-Fiber Bunch Cable, LC/SC/FC/ST/LSH, 0.9/2.0mm Breakout

Projects in the Philippines benefit from keeping the configuration, branch identification and installation requirement consistent across every participating site. This customized multi-fiber cable is a pre-terminated indoor item built exactly to the design 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 bunch design arranges the 0.9mm tight-buffered fibers around a central strength member inside a round trunk, giving a flexible, pulling-friendly cable for congested indoor pathways.

Specifications

Bend-insensitive glass in real pathways

Backbone routes turn through tight tray corners, congested risers and crowded vertical channels. The G.657.A1 bend-insensitive fiber in this factory-built assembly tolerates a 10mm fiber bend radius; as a result, a hurried routing decision during a night service work window is not intended to turn into a measurable penalty on the optical path. The glass remains fully compatible with the G.652.D plant it connects to.

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 equivalent section used in the outside plant; as a result, the factory-built assembly is not intended to become the weak point of the power 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.

Breakout geometry and why it matters

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 configuration suits protected routing inside panels and cassettes. Deciding on the geometry at order time means the factory-built assembly arrives matching the hardware it serves.

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 this backbone cable 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.

Planning a trunk route

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

Pre-terminated versus field termination

Terminating OS2 fiber in the field means a splicer, a tray mounting point, consumables and the craft time to do it well - multiplied by every fiber in this backbone cable. A pre-terminated item moves all of that work to the factory floor, where polishing, inspection and testing happen under controlled conditions. The installer who receives the fiber cable routes it, dresses the legs and mates the mating connectors; the optical path is ready for light the equivalent hour. For multi-fiber counts the saving should not be treated as linear but compounding, given that every field-terminated leg is a further chance for a rework visit.

Choosing the Fiber Count

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

Length Selection and Customization

Standard size options 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 provided beyond the list, including foot-based builds for projects specified in imperial units. Specifying the measured channel length keeps the slack out of the tray and the strain off the mating connectors.

Production Testing and Quality Assurance

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 factory-built assembly ships with dust caps on each connector interface and the test results provided on order.

Placing an Order and Factory Support

Refer to this design by fiber mode, fiber count, connector pair, breakout geometry and length when submitting a request for a quotation. For configurations outside the listed options - mixed connector families, jacket ratings, pulling eye, labeling or project packaging - send the need with the inquiry and the factory will validate the build before release to production. Customers in the Philippines can include multi-site labeling or documentation requirements when requesting a project quotation.
