Digitus LC to LC Fibre Optic Patch Cable OM5 Multimode Duplex 50/125µm LSZH 10m Lemon green

The Digitus DK-2533-10-5 is a 10 m LC-to-LC duplex fibre patch cable on wideband OM5 multimode 50/125 µm fibre, built for linking switches, servers, storage and patch panels through short-reach multimode optics in server rooms, offices and data centres.

Both ends carry small-form-factor LC duplex connectors, and the lemon green LSZH jacket follows the usual OM5 colour coding, which makes the link easy to recognise in a busy rack. Each cable ships with its own measurement protocol from the factory.

• 1 × Digitus LC–LC duplex OM5 fibre patch cable, 10 m
• Individual test report (measurement protocol) for the cable

• Plug one duplex connector into a multimode SFP/SFP+ transceiver or patch panel port at each end — one fibre carries transmit, the other receive.
• At 10 m this cable suits links between racks in the same row or across a small server room.
• Per IEEE 802.3, 10GBASE-SR reaches up to 400 m on OM5 — far more than this cable's 10 m, so the cable length is never the limiting factor.
• If the link stays dark after plugging in, reverse the two fibres at one end (Tx/Rx swap) — every duplex fibre link needs transmit on one side to meet receive on the other.
• The LSZH jacket gives off little smoke and no halogen gases in a fire, which is why it is the usual choice for offices, public buildings and enclosed server rooms.

• Single-mode optics (OS2 9/125 µm, typically 1310/1550 nm LX/LR/ER modules) — use a single-mode patch cable for those.
• Copper RJ45 ports — the switch or NIC needs an SFP/SFP+ slot with a multimode fibre transceiver fitted.
• Ports with SC or ST connectors — you need a cable with the matching connector at that end.
• Outdoor, underground or direct-burial runs — this is an indoor patch cable.
• OM5 wavelength-division benefits (SWDM, 40/100G over one pair) only appear with SWDM transceivers; with ordinary 850 nm optics it behaves like OM4.
