Fibre Patch Panels Explained Types, Connectors & How to Choose the Right One
Shop fibre patch panels →ODFsTransceivers
Every fibre link in a building ends at a patch panel. Choose the right one and the network is easy to test, trace and expand; choose the wrong one and you run out of ports, mix incompatible connectors or have to re-splice. This guide explains the types of fibre patch panel, the connector and fibre options, and how to choose.

A fibre patch panel (also called a fibre optic patch panel or fibre termination panel) is a 19-inch rack-mounted enclosure that terminates incoming fibre cables onto front adapters. Inside, fibres are spliced to pigtails or connected through, and stored in trays. At the front, short patch cords connect each port to switches, routers, transceivers or other panels.
Types of Fibre Patch Panel
Sliding fibre patch panel
The tray slides forward out of the rack like a drawer, so you can reach the splice trays from the front without removing the panel. The most common type in comms and server racks. Sliding 1U, 24 LC/UPC duplex single mode.
Pivoting fibre patch panel
The front tilts down or swings out on a pivot, giving access to the trays in tight racks where there is no room to slide. Telenco UK pivoting panels come in 24 and 48 fibre versions with LC/APC, SC/APC and SC/UPC adapters. Pivoting 1U 48FO LC/APC.
Fixed fibre patch panel
A simple fixed panel for smaller installations and legacy links, such as a 16-way ST/ST 1U panel or a modular Excel Enbeam LC panel.
Modular chassis and ODFs
For hundreds of fibres, a modular chassis takes plug-in splicing and patching modules, and a full optical distribution frame handles thousands. See our ODF range.
Loaded, Pass-Through or Empty?
The same panel is often sold in several configurations. Choosing the right one saves hours on site.
| Configuration | What you get | Use when |
|---|---|---|
| Loaded with pigtails | Adapters fitted and factory-terminated pigtails in splice trays | You will fusion splice a loose-tube or ribbon cable on site |
| Pass-through / through connectors | Adapters only, no pigtails | You are using pre-terminated cables or fibre trunks |
| Cassettes or trays | Plug-in cassettes or splice trays per group of fibres | You want to add capacity in stages |
| Empty | Panel and adapter plates only | You will specify and fit your own adapters |
Choosing Connectors, Polish and Fibre Type
- LC or SC. LC is a small form factor connector with a 1.25 mm ferrule, roughly half the footprint of SC, so it suits high-density panels. LC matches switch ports and SFP transceivers. SC (2.5 mm ferrule) is widely used in telecoms and FTTx. ST is found on older multimode links.
- UPC or APC. UPC (blue) has a flat polish; APC (green) has an 8° angled polish with lower back reflection, preferred for single mode, PON and RF-over-fibre. Never mix them.
- Single mode or multimode. Single mode (OS2, often bend-insensitive G.657A2) is for long distances and telecoms. Multimode OM3 and OM4 suit short data centre links with 850 nm optics.
- Simplex or duplex. Duplex adapters carry a transmit and receive pair; "24 duplex" usually means 48 fibres.

How Many Ports Do You Need?
Count fibres
Count every fibre in every incoming cable, not just the ones you light today.
Pick density
LC duplex for the most fibres per U; SC where the network uses SC.
Add growth
Allow 25–50% spare ports and at least one spare panel space in the rack.
Plan cable management
Fit a horizontal cable guide between panels and switches.
Route between racks
Run patch cords between racks in yellow fibre raceway.
Label and test
Label both ends, then test insertion loss and keep the results.
Where Fibre Patch Panels Are Used
In enterprise buildings, patch panels sit in network and comms cabinets alongside switches. In data centres they are fitted at the top of each server rack or in dedicated network racks, linked back to the meet-me room or main distribution area by fibre trunks. In exchanges and large halls, the termination function moves to an ODF. See how it all fits together in our data centre cable management guide.
Fibre Patch Panel FAQs
What is a fibre patch panel?
A fibre patch panel is a rack-mounted enclosure where incoming fibre cables are terminated onto adapters, so equipment can be connected with short patch cords. It protects the splices or connectors, organises the fibres and gives a fixed, labelled point for testing and re-patching.
What is the difference between a fibre patch panel and an ODF?
A fibre patch panel is usually a single 1U or 2U panel in a network or server rack. An optical distribution frame (ODF) is a larger, dedicated frame or chassis system that terminates and cross-connects hundreds or thousands of fibres, typically in exchanges, meet-me rooms and large data centres.
Should I choose LC or SC adapters?
LC is half the size of SC, so it doubles the port density in the same 1U and is standard on switches and SFP transceivers. SC is common in telecoms, FTTx and PON networks. Choose the connector that matches your equipment and patch cords.
What does a patch panel loaded with pigtails mean?
The panel is supplied with adapters fitted and short factory-terminated pigtails in the splice trays. You fusion splice the incoming cable fibres to the pigtails, which gives low-loss, factory-quality connectors without field termination.
Can I mix APC and UPC connectors?
No. APC connectors have an 8° angled end face and UPC connectors a flat one. Mating them causes high loss and can damage the end faces. Use APC (green) or UPC (blue) throughout a link.
