EFB-Elektronik K5455.0,25 Cat 5e SF/UTP Patch Cable, 0.25 m Grey

Cat 5e SF/UTP0.25 m · Grey100 MHz · 1 GbpsPVC jacket

The EFB-Elektronik K5455.0,25 is a 0.25 m grey Cat 5e SF/UTP patch cable with RJ45 plugs on both ends, built for patch-panel-to-switch jumpers, stacked switches and tight rack runs. The SF/UTP construction wraps all four pairs in foil plus a braided screen, which helps in cabinets full of power cables, while the Cat 5e rating comfortably carries Gigabit Ethernet over this short distance. Part number K5455.0,25 (EAN 4049759064969) identifies this exact length and colour, so you can reorder identical cords when you extend a cabinet or colour-code a new VLAN.

Before you buy
This cord uses copper-clad aluminium (CCA) conductors and a PVC jacket — fine for Gigabit data jumpers, but not the right choice for PoE cameras/access points or for installations that require halogen-free (LSZH) cabling. Cat 5e tops out at 1 Gbps; for 2.5/5/10 GbE ports pick a Cat 6A cord.

Key Features

 
Foil + braid screen
SF/UTP shielding (overall foil and braid) keeps crosstalk and interference from nearby power and fan cables out of the data pairs.
 
Snagless moulded boots
Moulded strain-relief boots protect the latch from snapping off when cords are pulled through dense patch panels.
 
Gigabit-ready Cat 5e
100 MHz Cat 5e performance covers 10/100/1000BASE-T — every Gigabit switch, router and PC port.

Frequently Asked Questions

Does the K5455.0,25 work with my switch, router or patch panel?
Yes. It is a standard RJ45-to-RJ45 Cat 5e patch cord wired straight-through (T568B), so it connects any Ethernet port to any other — switches, routers, NAS units, access points, patch panels and PCs. Modern ports auto-negotiate speed and handle crossover automatically.
Is a 0.25 m cable long enough?
At 0.25 m (25 cm) it is a jumper, not a room cable: it is sized for linking a patch panel to the switch directly above or below it, or two stacked switches, without slack loops cluttering the cabinet. For desk or wall-outlet runs choose 1–3 m instead.
What is the difference between the K5455.0,25 and a Cat 6A S/FTP cord?
The K5455.0,25 is Cat 5e (100 MHz, 1 Gbps) with CCA conductors and PVC jacket — a budget data jumper. A Cat 6A S/FTP cord such as EFB MK6001 or EC0202000 adds 500 MHz, 10 Gbps, solid copper, LSZH and PoE support; choose it for 10 GbE, PoE or halogen-free sites.
Can I use the K5455.0,25 for PoE devices?
It is not recommended. EFB publishes no PoE class for this CCA cord; aluminium-core conductors have higher resistance and heat up under PoE current. For PoE cameras, phones and access points use a solid-copper Cat 6/6A cord.
Singular Expert Insight
The K5455.0,25 is the economical way to patch Gigabit gear: screened, snagless and cheap enough to buy by the dozen. Its limits are the CCA core, PVC jacket and Cat 5e ceiling, so we point PoE, LSZH and multi-gig installs to EFB Cat 6A cords (MK6001 or EC0202000 series) instead. Browse the full range of network cables for other lengths and colours, or pair it with our network switches.

Buyer's Guide

Buy it if
You need low-cost screened Gigabit jumpers for data-only ports in a rack or home cabinet.
Skip it if
You power devices over PoE, need 2.5/10 GbE, or your site requires halogen-free (LSZH) cable.
Also consider
EFB MK6001 Cat 6A S/FTP LSZH cords for 10 GbE and PoE, or ECOLAN Cat 6 for a middle ground.
