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

Projects in the Philippines benefit from keeping the configuration, branch identification and installation requirement consistent across every participating site. This duplex armored patch cable pairs two LC UPC connectors on an OS2 9/125µm single-mode item protected by a helical stainless steel tube. The 3.0mm riser-rated (OFCR) jacket keeps the fiber cable flexible adequate 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.

Specifications

Why steel armor instead of a conduit

Conventional patch patch leads depend on the surrounding duct or tray for mechanical protection. Where cables cross open floors, shared ceilings or industrial spaces, that protection should not be treated as always provided. The helical steel tube inside this factory-built assembly wraps the buffered fibers directly; as a result, the fiber cable itself carries the crush and rodent resistance. Installation teams may channel it through areas that would otherwise require metal conduit, which reduces both material cost and deployment 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. The duplex LC interface is the standard joint for SFP, SFP+, SFP28, QSFP+ and QSFP28 transceivers; as a result, one cable product line 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 fiber cable may readily be mixed into existing 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) configuration should ideally be chosen instead; where low smoke and zero halogen are specified, the LSZH configuration of this equivalent LC-LC design is provided. 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 each case the pattern is the equivalent: the channel is fixed, the cord is handled during every 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.

Length selection and customization

Standard size options 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. Non-standard lengths beyond this range are manufactured to order. The equivalent design may additionally be supplied with black or white jackets, APC polish, or alternative connectors through the customized duplex armored cable program. Specifying the particular channel length avoids both the slack storage problem of an overlong cord and the strain risk of one that is too short.

Production testing and quality assurance

Each completed 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 values, 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.

Placing an Order and Factory Support

Refer to the LC-LC OS2 duplex armored product line when submitting a request for a quotation and state the channel length, jacket rating and connector polish applicable. For non-standard combinations of length, color, connector or jacket, send the need with the inquiry and the factory will validate the manufacturable specification before release to production. Customers in the Philippines can include multi-site labeling or documentation requirements when requesting a project quotation.
