A buying guide covering 4U server cabinets, Cat6 patch cords in common lengths (2M, 3M, 20M), and gigabit Ethernet cable — built around what UAE buyers actually search for.
If you're setting up or expanding a server room, two things almost always come up together: rack space and cabling. This guide covers the specific sizes and lengths people search for most — 4U server cabinets, 3-meter gigabit Ethernet cable, and 20M Cat6 patch cords — with real specs and options available in the UAE.
Rack units (U) measure vertical space inside a server cabinet — 1U equals 1.75 inches (44.45mm), a standard defined by the Electronic Industries Alliance (EIA-310). A 4U cabinet or chassis gives you 4 rack units of usable mounting space — enough for a handful of network switches, a small server, or patch panels in a compact footprint.
We stock several 4U options depending on what you're mounting:
For larger deployments beyond 4U, we also stock APC's 24U Easy Rack Cabinet (19" bracket width, with roof, side panels, and castors) for full server room builds.

Patch cord length matters more than people expect: too short and it won't reach; too long and excess cable creates clutter and potential signal degradation over unnecessarily long runs. Per the TIA/EIA-568 cabling standard, Cat6 supports Gigabit Ethernet up to 100 meters, so all the lengths below are well within spec.
A 3M cable is a common in-rack or short-run length — long enough to route between a patch panel and a switch a few units away, without excess slack. Our Norden Cat6 U/UTP Patch Cord (3M, Grey PVC) supports full Gigabit Ethernet speeds and is available in-stock for same-day dispatch.
20M cords are typically used for longer in-building runs — connecting a rack in one room to a device or outlet in another — without needing a full structured cabling install. We stock:
Color-coding longer runs like this (orange vs blue) is a common practice for quickly identifying circuit types or VLANs at a glance in larger installations.
We also stock 2M patch cords (Grey and Orange PVC) for short in-rack jumps, and a Norden Cat6 S/FTP Patch Cord (2M, Grey, Shielded) for environments with higher electromagnetic interference, plus Cat6A U/UTP options where 10 Gigabit speeds are needed instead of standard Gigabit.

| Use Case | Recommended Length |
|---|---|
| Within the same rack (patch panel to switch) | 0.5M – 2M |
| Between adjacent racks or a nearby desk | 3M – 5M |
| Across a room or between floors within a building | 10M – 20M |
| Beyond 20M | Consider bulk cable + proper structured cabling instead of a single long patch cord |
Cat6 supports full Gigabit Ethernet up to 100 meters per the TIA/EIA-568 standard. Beyond that, signal degradation can affect performance, and fiber optic cable becomes the better option for longer distances.
Depends on the equipment — a 4U space typically fits 2-4 network switches, or one to two 1U-2U servers plus a patch panel. Check your specific device's rack-unit height (usually 1U or 2U) before ordering.
Yes — alongside ready-made patch cords, we stock bulk Cat6 and Cat6A cable reels for structured cabling installations. See our networking cables page for the full range.
Whether you're fitting a compact 4U cabinet into a small server room or running a 20M patch cord across a building, getting the right size and length upfront saves you from clutter, signal issues, or a cabinet that doesn't fit your equipment.
