Single-mode fibre patch cable

This single-mode fibre patch cable carries data up to 50 times farther than multimode alternatives, making it suitable for long-haul links between network equipment. The yellow jacket identifies the OS2 single-mode construction and the one-metre length fits short rack-to-rack or desktop runs.

LC duplex connectors and OFNR riser rating

Duplex LC connectors are almost half the size of traditional ST or SC terminations, freeing panel space in dense patch panels or wall outlets. The PVC jacket carries an OFNR riser rating, so the cable can be routed vertically between floors without additional conduit.

No software or accessories included

The product ships as a standalone cable with no bundled software, adapters or management tools. Installation is limited to physical connection, leaving configuration entirely to the attached networking hardware.

Questions about this item

What is the maximum single-mode distance this OS2 cable supports compared to multimode?

The OS2 single-mode design transmits up to 50 times farther than multimode fibre, making it suitable for long-haul links.

How much heat does the OFNR-rated PVC jacket add during continuous riser installation?

The passive cable generates no heat; the OFNR rating only certifies flame-retardant jacket material for vertical runs.

Which LC patch panels or transceivers must I already have to connect this duplex cable?

You need matching LC duplex ports — either patch-panel couplers or transceiver interfaces — on both ends.
