LC to LC Duplex Armored Fiber Patch Cable, OS2, LSZH

This duplex armored patch cable terminates two LC UPC connectors on an OS2 9/125µm single-mode assembly with a low smoke zero halogen jacket over a helical stainless steel tube. It answers the specifications that forbid PVC and riser compounds: tunnels, stations, ships, high-occupancy buildings and data halls where smoke and corrosive gas from a burning cable are treated as seriously as the fire itself.

Product Highlights

• LC UPC to LC UPC duplex, OS2 9/125µm single mode
• LSZH jacket: low smoke, zero halogen in a fire
• Helical stainless steel armor against crush, impact and rodents
• G.657.A1 bend-insensitive fiber, 10/5D bend radius
• Insertion loss ≤0.3dB, return loss ≥50dB
• Stock lengths 1m to 30m; custom lengths and jackets on request

When standard jacket compounds burn, they release dense smoke and corrosive halogen gases; in a tunnel, metro station, ship or packed office, that smoke is often the greater danger to people and to electronic equipment. LSZH compounds drastically reduce both. Wherever the building specification names low smoke zero halogen cabling, this is the armored cord that meets it without giving up mechanical protection.

Optically this assembly is identical to the OFCR-rated LC-LC cord: the same G.657.A1 bend-insensitive glass, the same 0.3dB insertion loss ceiling, the same 1310/1550nm single-mode window. The difference is only the jacket system. That means a project can mix LSZH and riser versions across building zones while keeping one optical specification and one supplier part family.

The steel tube protects the fibers from the building; the LSZH jacket protects the building occupants from the cable. The combination suits evacuation routes, public concourses, transport hubs and any pathway where an armored cord would normally raise a jacket-compliance question. The cord stays 3.0mm and dresses exactly like a standard jumper.

When the project specification calls for LSZH, name it on the cord schedule explicitly rather than assuming the jacket follows the backbone cable. Patch cords are frequently procured separately and default to riser compounds. This family makes the LSZH requirement easy to satisfy, since the LSZH build carries the same optical and mechanical ratings as the riser version, differing only in the jacket compound.

Standard 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. Custom lengths beyond this range are manufactured to order. In public-area installations the route is usually surveyed in advance, so ordering to the measured length keeps excess cable out of the evacuation pathway. Specifying the exact route length avoids both the slack storage problem of an overlong cord and the strain risk of one that is too short.

Every assembly is terminated with precision zirconia ferrule LC connectors and measured for insertion loss and return loss before packing; the 0.3dB and 50dB figures are verified per cord. End-face geometry is inspected for consistent physical contact, and the LSZH jacket is batch-tested for the compound it is specified to be.
