For Nigerian deployments, this product should be evaluated as part of the complete network path, including its connectors, mapping and acceptance values. This made-to-order multi-fiber cable is a pre-terminated indoor assembly built exactly to the configuration the project specifies: connector styles and polish at every 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 bunch construction 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.

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 the completed assembly tolerates a 10mm fiber bend radius, which means a hurried routing decision during a night maintenance window does not itself turn into a measurable penalty on the link. 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 each wavelength-multiplexed service in between. The glass is the same category used in the outside plant, which means the completed product does not itself become the weak point of the channel loss budget. At 1310 and 1550nm the attenuation stays a fraction of a decibel per kilometer, and every 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. Equal-length legs suit a straight row of adjacent ports; at the same time, 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 variant suits protected routing inside panels and cassettes. Choosing the geometry at order time means the completed product 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 the backbone trunk from twisting, which matters on long riser runs and congested trays. The fitting load rating on the datasheet is the number the pulling rope ought to respect, not the weight of the reel.
Planning a trunk route
A multi-fiber trunk is planned once and fitted once, which means the planning deserves the hour it takes. Measure the route through the actual containment, note the bend space at the two cable ends, and decide which end gets pulled. State the pulling eye requirement with the order if the route is long or congested. At the far end, leave the dressing slack the rack panel or cassette needs - the datasheet breakout lengths are the default, and other geometries are confirmed before the build starts.
Pre-terminated versus field termination
Terminating OS2 fiber in the field means a splicer, a tray position, consumables and the craft time to do it well - multiplied by each fiber in the backbone trunk. A pre-terminated assembly moves all of that work to the factory floor, where polishing, inspection and testing happen under controlled conditions. The installer who receives the cable assembly routes it, dresses the legs and mates the connector interfaces; the link is ready for light the same hour. For multi-fiber counts the saving cannot be considered linear but compounding, as each field-terminated leg is another chance for a rework visit.
Fiber Count Selection
This construction is built with 2 Fibers per trunk, terminated and tested as a whole assembly.
Custom Length Production
Stock length choices cover the common routes: 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 10m (33ft), 15m (49ft), 20m (66ft), 30m (98ft), 25m (82ft), with made-to-order length available beyond the list, including foot-based builds for projects specified in imperial units. Specifying the measured route length keeps the slack out of the tray and the strain off the connector interfaces.
Inspection and Test Procedures
Each trunk is terminated with precision zirconia ferrule connectors and optically tested leg by leg before packing: insertion loss and return loss are verified on every fiber, and end-face geometry is inspected for consistent physical contact. The completed product ships with dust caps on every optical connector and the test results available on request.
Ordering Information and Support
Refer to this configuration by fiber mode, fiber count, connector pair, breakout geometry and length at the request stage a quotation. For configurations outside the listed options - mixed connector families, jacket ratings, pulling eye, labelling or project packing - send the requirement with the enquiry and the factory will establish the build before the build starts. For Nigerian orders, our team can check the requirement before coordinating manufacture and international delivery.
