equip LC/APC to LC/APC Fibre Optic Patch Cable, OS2 Single-Mode 9/125µm, Simplex, LSZH Armoured, 5m, White

The equip 255945 is a simplex OS2 single-mode fibre optic patch cable (9/125µm) with LC connectors on both ends (APC polish), 5m long with an LSZH jacket and internal spiral armour. It is made for connecting switches, servers, media converters and fibre patch panels in building backbones, telecom rooms and long single-mode links.

The jacket follows the standard colour code (white for OS2), so the cord is easy to identify in a mixed rack. LC is the small push-latch connector used on SFP/SFP+ optics, on most current switch and server ports and on high-density patch panels.

• 1× equip LC/APC–LC/APC OS2 simplex fibre patch cable, 5m
• Transceivers, couplers and cleaning tools are not included

• OS2 single-mode fibre carries the 1310/1550 nm light used by single-mode optics (1000BASE-LX, 10GBASE-LR and similar). The same cord type serves short patches and long backbone links — reach is set by the transceivers and the whole link, not by this cord.
• Simplex means one single fibre. A standard two-fibre transceiver needs two simplex cords or one duplex cord; a single simplex cord on its own suits BiDi (single-fibre) optics, splitters and PON/FTTH patching.
• APC (Angled Physical Contact) end faces are polished at 8°, keeping back reflection very low — the norm for FTTH/PON, CATV/RF-over-fibre and many telecom panels. APC connectors are green by convention.
• The internal spiral armour gives better resistance to crushing, bending and twisting than an ordinary patch cord, which helps in busy racks and cable trays; the 2.8 mm diameter still routes easily.
• The LSZH (low smoke, zero halogen) jacket is meant for indoor use where fire safety matters: in a fire it gives off less smoke and no corrosive halogen gases.
• At 5m, it suits runs to the next rack or across a small room.

• Multimode transceivers (SX, SR, 850 nm) or multimode panels — a single-mode cord will not give a reliable link with them.
• UPC/PC ports (blue single-mode connectors) — APC must only mate with APC; mixing damages the end faces and causes high loss.
• Ports with a different connector type — this cord has LC on both ends only; for SC or ST ports you need a cable with those connectors.
• A standard two-fibre (duplex) transceiver with only this one cord — it needs two simplex cords or a duplex cord.
• Copper RJ45 ports — fibre needs an optical transceiver or media converter at each end.
• Outdoor, underground or direct-burial runs — this is an indoor patch cable.
