LC to LC Duplex Armored Fiber Patch Cable, OS2, Riser (OFCR)

For Pakistani procurement and engineering teams, the specification provides a practical basis for checking compatibility before production is requested. This duplex armored patch cable pairs two LC UPC connectors on an OS2 9/125µm single-mode unit protected by a helical stainless steel tube. The 3.0mm riser-rated (OFCR) jacket keeps the installed cable flexible sufficient for cabinet and under-floor routing while the steel armor absorbs crushing, pulling and rodent damage that would interrupt an ordinary patch cord. G.657.A1 bend-insensitive glass keeps attenuation stable even where the pathway turns tightly around trays and rack posts.

• Riser (OFCR) flame rating for vertical building pathways

Specifications

Why steel armor instead of a conduit

Conventional patch patch cords depend on the surrounding duct or tray for mechanical protection. Where cables cross open floors, shared ceilings or industrial spaces, that protection is not to be considered always offered. The helical steel tube inside the product assembly wraps the buffered fibers directly, and therefore the installed cable itself carries the crush and rodent resistance. Technicians can path it through areas that would otherwise require metal conduit, which reduces the two material cost and installation time while keeping the pathway smaller and easier to reconfigure later.

OS2 single-mode performance in duplex links

OS2 glass at 1310/1550nm supports the long-reach single-mode optics used in campus backbones, carrier access networks and data center interconnects. Because the duplex LC interface is the standard interface for SFP, SFP+, SFP28, QSFP+ and QSFP28 transceivers, one cable series covers links from 1G through 100G and beyond. G.657.A1 bend tolerance is fully compatible with legacy G.652.D plant, which means the installed cable can also be mixed into present single-mode infrastructure without changing loss budgets.

Understanding the OFCR riser rating

OFCR stands for optical fiber conductive riser: a riser-rated cable whose metallic armor makes it conductive under building codes. The riser rating permits vertical runs between floors in shafts and riser closets. Where the pathway passes through air-handling spaces, a plenum (OFNP) model ought to be specified instead; where low smoke and zero halogen are specified, the LSZH version of this identical LC-LC build is offered. Matching the jacket to the building section is part of the ordering discussion, not an afterthought.

Where armored duplex cords are deployed

The typical homes for this cord are data center cross-connect fields, campus backbone handoffs, industrial control rooms and any pathway shared with power cabling or foot traffic. In every case the pattern is the identical: the path is fixed, the cord is handled during each reconfiguration, and an unprotected jumper would eventually be crushed, kinked or chewed. The armored build removes that failure mode without changing how the cord dresses or connects.

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), covering the common rack-to-rack, access and frame connections this cord is built for. Special lengths beyond this range are manufactured to order. The identical build can further be supplied with black or white jackets, APC polish, or alternative connectors through the custom-built duplex armored cable program. Specifying the precise path length avoids the two the slack storage problem of an overlong cord and the strain risk of one that is too short.

Test standards and quality control

Every manufactured assembly is terminated with precision zirconia ferrule connectors and measured for insertion loss and return loss before packing. The 0.3dB insertion loss ceiling and 50dB minimum return loss are verified specifications, not design targets. End-face geometry is checked to keep the physical contact consistent across repeat mating, and the ferrules are rated for up to one thousand insertion cycles, which matters in patching fields that are reconfigured frequently.

Ordering Details and Factory Support

Refer to the LC-LC OS2 duplex armored series when specifying a quotation and state the path length, jacket rating and connector polish project-specific. For non-standard combinations of length, color, connector or jacket, send the specification with the request and the factory will make certain of the manufacturable specification before factory assembly. For Pakistan, a clear port or maintenance schedule helps us confirm the correct factory-built configuration before supply.
