Customized OM3 Indoor Multi-Fiber Breakout Cable, LC/SC/FC/ST/LSH/Unterminated
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. Because the tight-buffered breakout build gives every fiber its own 2.0mm or 0.9mm leg, the installed trunk terminates directly into panels and equipment without a splice tray or fan-out kit.

OM3 for existing multimode plants
This OM3 unit matches the installed base of OM3 link cabling: 10G links to 300 meters and 40/100G SR4 links to 70 meters. When the permanent connection is OM3, trunking with OM3 keeps the link specification homogeneous and the test reports clean.
Keeping multimode links healthy
Multimode links fail more frequently from contamination than from fiber damage. Every ferrule must be inspected and cleaned before plugging in, and the dust caps should stay on until the moment of interface. These habits matter more than any specification on the datasheet, and they are the reason these assemblies ship capped and tested.
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.
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.
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.
Pre-terminated versus field termination
Terminating OM3 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,.
Fiber Count Choices
Fiber count is specified at order time: 4 Fibers, 6 Fibers, 8 Fibers, 12 Fibers, 16 Fibers, 24 Fibers are standard options for this build. Selecting the count is a capacity decision - plan the active links, add the spares the servicing practice calls for, and the installed trunk arrives with every leg terminated and tested.
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), 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.
