Yellow duplex fibre cable with blue LC connectors, two metres long

STARTECH

STARTECH SMDOS2LCLC2M 2m LC-LC OS2 Single Mode Duplex Fibre Optic Cable 9/125 100G LSZH

SKU CH-RFQ6-71QGG

2 metre OS2 single-mode duplex fibre cable with LC connectors for 100G links, low insertion loss and LSZH jacket

  • 2 m length suits short patch-panel runs
  • LC duplex connectors enable standard single-mode patching
  • OS2 9/125 µm fibre supports 100 G links
  • LSZH jacket reduces smoke in confined spaces
  • Low insertion loss maintains signal integrity over distance

2-metre OS2 single-mode duplex patch cord

This cable is a 2 metre LC to LC duplex jumper built to OS2 single-mode specification with a 9/125 micron core. It carries a low insertion loss rating and an LSZH jacket, making it suitable for indoor campus and data-centre links up to 100 GbE. The ceramic ferrule UPC polish is designed for reliable long-haul transmission.

Suited to network engineers extending single-mode

It suits installers who need a pre-terminated duplex link between patch panels, transceivers or distribution frames where OS2 single-mode is specified. It does not suit teams requiring multimode fibre for short-reach rack connections, nor anyone needing angled-polish APC connectors for return-loss sensitive systems.

9/125 micron OS2 single-mode core diameter

The 9/125 micron core defines single-mode operation and determines compatibility with OS2 transceivers and link budgets. If the network design calls for multimode OM3 or OM4 cores, this cable will not work and a different fibre type must be sourced.

Questions about this item

What does the OS2 single-mode 9/125 specification mean for the distances this 2 m duplex cable can cover?

OS2 single-mode fibre with a 9 µm core and 125 µm cladding is designed for long-haul links; at 2 m it simply provides a low-loss patch between transceivers without limiting the kilometres the standard supports.

What physical space and connector type are required to plug in the LC duplex ends of this jumper?

Each end uses a standard LC duplex connector that occupies one SFP/SFP+ transceiver port; the 2 m yellow LSZH jacket needs only enough slack to route between adjacent rack units or wall boxes.

How is the cable installed, and which polarity step is most often missed?

Insert each LC connector until it clicks into the transceiver; the critical step is matching Tx on one side to Rx on the other so the duplex fibres cross correctly.
