Custom Duplex Armored Fiber Patch Cable, OS2, LC/SC/FC/ST/LSH
For Pakistani procurement and engineering teams, the specification provides a practical basis for checking compatibility before production is requested. This is the configured-to-order duplex armored platform: two fibers of OS2 9/125µm G.657.A1 glass inside a helical stainless steel tube, terminated with any combination of LC, SC, FC, ST or LSH connectors in UPC or APC polish, and jacketed in riser (OFCR), LSZH or plenum (OFNP) compound in blue, black or white. Instead of adapting a stock cord to the job, the cord is built for the job from the start. For Pakistani projects, include this point in the technical enquiry and final installation checklist.

One platform, every connector combination
LC on the transceiver, ST on the legacy panel, FC on the test set, LSH on the carrier frame: real networks mix interfaces, and this platform terminates any of them on either end of the identical armored duplex cord. Because hybrid builds arrive as one tested unit, the adapter housing pairs and their extra loss merely never enter the connection.
Choosing the jacket: OFCR, LSZH or OFNP
The jacket follows the building zone, not the other way round. Riser (OFCR) suits vertical shafts and general pathways; LSZH is specified for occupied public spaces, tunnels and transport; plenum (OFNP) is project-specific where the path crosses air-handling space. The armor and the optical core stay the identical across all three, and therefore one diagram can mix jackets by zone without changing the optical budget.
How custom production runs
Send the optical interface mix, polish, jacket, color and length; the factory confirms the manufacturable specification, then terminates, armors and tests the patch cords to that diagram. Because each cord in the batch is measured for insertion loss and return loss against the identical limits as the stock range, a bespoke build carries no quality penalty.
Documentation and batch consistency
Every bespoke build is confirmed against a written setup before factory assembly, and that setup becomes the reference for repeat orders. Because label text, leg marking and packing can all be added to the identical diagram, the second batch arrives identical to the first. For projects rolled out in phases, this repeatability is normally worth more than any single specification line.
Color coding with black and white jackets
Beyond the standard blue, the duplex platform is jacketed in black or white on specify. Black serves outdoor-adjacent and security-conscious routes where the installed cable ought to not draw the eye; white disappears into finished interiors, hotel corridors and office raceway. Some administrations further use jacket color to discrete networks or security zones on the identical frame. State the color with the setup and it is built into the jacket, not sleeved on afterward.
Standard and custom length options
Catalogue lengths are stocked for fast delivery: 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 10m (33ft), 15m (49ft), 20m (66ft) and 30m (98ft). Because each cord is built to order, any length in between or beyond this range can also be produced; for long runs the factory confirms reel and packing specifications with the quotation.
Test standards and quality control
Bespoke patch cords are tested to the identical limits as the stock range: 0.3dB insertion loss ceiling and polish-suitable return loss, verified per unit before packing. Because ferrule geometry is checked on each end face, and APC ends are angle-verified, a mixed-polish build performs exactly as its two polishes indicate.
Ordering Details and Factory Support
Send the project-specific setup: connector types per end, polish per end, jacket rating, color and length. The factory confirms the manufacturable specification and lead time with the quotation; drawings or photos of the present plant are welcome and speed up confirmation. For Pakistan, a clear port or maintenance schedule helps us confirm the correct factory-built configuration before supply.
