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

New Zealand engineering teams can use the documented values below to compare the product with the intended channel and as-built requirements. This duplex armored patch cable terminates two LC UPC connectors on an OS2 9/125µm single-mode item with a low smoke zero halogen jacket over a helical stainless steel tube. It answers the detailed 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

• 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
• LC UPC to LC UPC duplex, OS2 9/125µm single mode
• LSZH jacket: low smoke, zero halogen in a fire

Specifications

LSZH jackets for occupied and enclosed spaces

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 typically the greater danger to people and to electronic hardware. LSZH compounds drastically reduce the two. Wherever the building specification names low smoke zero halogen cabling, this is the armored cord that meets it without giving up mechanical protection.

Same OS2 core as the riser version

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

Armor plus LSZH: protection inside and out

The steel tube protects the fibers from the building; the LSZH jacket protects the building occupants from the relevant 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.

Specifying LSZH in project documents

When the project specification calls for LSZH, name it on the cord schedule explicitly rather than assuming the jacket follows the backbone cable. Patch patch leads are frequently procured separately and default to riser compounds. Since the LSZH build carries the matching optical and mechanical ratings as the riser configuration, differing only in the jacket compound, this product line makes the LSZH requirement easy to satisfy,.

Length range and customization

Regular length versions 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. Project-built lengths beyond this range are manufactured to order. In public-space installations the channel is typically surveyed in advance; therefore, ordering to the measured length keeps excess cable out of the evacuation pathway. Specifying the particular channel length avoids the two the slack storage problem of an overlong cord and the strain risk of one that is too short.

Optical testing and quality checks

Each optical 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.

How to Specify and Order

Reference against the LC-LC OS2 LSZH armored product line with the channel length stated and the LSZH requirement referenced. Hybrid LC-SC and SC APC versions exist in the matching jacket configuration, and further connector mixes are offered through the made-to-order armored program. New Zealand project orders can include documentation and labeling requirements alongside the technical configuration.
