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

Singapore high-density designs should assess this item together with panel access, cable routing and the complete optical loss allowance. This duplex armored patch cable terminates two LC UPC connectors on an OS2 9/125µm single-mode product with a low smoke zero halogen jacket over a helical stainless steel tube. It answers the stated 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.

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 commonly 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.

Same OS2 core as the riser version

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

Armor plus LSZH: protection inside and out

The steel tube protects the fibers from the building; the LSZH jacket protects the building occupants from this optical 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 leads are frequently procured separately and default to riser compounds. Since the LSZH build carries the corresponding optical and mechanical ratings as the riser variant, differing only in the jacket compound, this range makes the LSZH requirement easy to satisfy,.

Length choices and custom production

Standard cable 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. Lengths built to order beyond this range are manufactured to order. In public-zone installations the pathway is generally surveyed in advance; consequently, ordering to the measured length keeps excess cable out of the evacuation pathway. Specifying the specific pathway length avoids both the slack storage problem of an overlong cord and the strain risk of one that is too short.

Quality assurance and factory testing

Each completed 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.

Quotation and Factory Support

Use against the LC-LC OS2 LSZH armored range with the pathway length stated and the LSZH requirement referenced. Hybrid LC-SC and SC APC versions exist in the corresponding jacket arrangement, and further connector mixes are obtainable through the custom armored program. Singapore and regional project orders can be reviewed for interface compatibility, packing details and delivery coordination.
