Digitus Pre-Assembled Fibre Breakout Cable — Single-Mode OS2, 8 Fibres, LC/UPC, 100 m
8 fibres · LC/UPC both endsOS2 · 9/125 µm100 mIndoor/outdoor · LSOH
The Digitus pre-assembled universal breakout cable (DK-2A338U100BK-BBB) is a 100 m factory-terminated fibre cable with 8 single-mode OS2 fibres, each ending in its own LC/UPC connector at both ends. It links two racks, floors or buildings with 4 duplex fibre links in one 6.0 mm cable — no splicing on site.
Each fibre is individually protected inside the breakout construction, and both ends are shipped inside a protective tube with a pulling aid, so the cable can be drawn through ducts with the connectors already fitted. Digitus supplies a test protocol with every cable and rates it for indoor and outdoor use, including links between cabinets without potential differences.
Before you order: measure the route before ordering — a pre-terminated cable cannot be shortened. It has LC/UPC connectors only; single-mode APC (green) ports and multimode equipment will not work.
What's in the Box
- 1 × pre-assembled breakout cable, 100 m, 8 fibres, LC/UPC on both ends
- Pulling aid and protective tube on both ends
- Test protocol (measurement report)
- Patch panels, LC couplers and patch cords are not included
What It Means in Practice
- Pull the cable through, remove the protective tubes and plug the LC connectors into panel couplers — the fibres are already terminated and tested.
- 8 fibres give 4 duplex links, or spare fibres for future growth.
- OS2 single-mode with bend-insensitive G.657.A1 fibre suits long building-to-building runs and 10G/25G/100G long-reach optics.
- Insertion loss is max. 0.3 dB and return loss min. 50 dB per connector, according to Digitus.
What Will Not Work
- Multimode (OM3/OM4) transceivers or panels.
- SC or APC ports without adapters or hybrid patch cords.
- Cutting to length on site: it is pre-terminated at both ends.
- Direct burial without a duct: Digitus lists indoor and outdoor use, not direct burial.

Frequently Asked Questions
What length should I order?
Measure the actual cable route including vertical runs and slack loops in each rack, then pick the next length up. A pre-terminated cable cannot be cut.
How do I terminate it in the rack?
Plug the LC connectors into LC duplex couplers in a fibre patch panel; then use short LC patch cords to the switch.
Can it run between buildings?
Digitus rates it for indoor and outdoor use, including between cabinets without potential differences. For underground runs, pull it through a duct.
Singular Expert Insight · Buyer's Guide
A pre-terminated breakout cable is the fastest way to add 8 fibres between two points without a fusion splicer — the trade-off is that the length must be right first time. For the patch cords that finish the link at each end, see our
fibre and network cables.
✓ Buy it if you need 8 single-mode OS2 fibres over 100 m, terminated and tested, indoors or outdoors in duct.
✕ Skip it if your route length is uncertain, or your equipment uses multimode optics.
→ Also consider Digitus breakout cables in other lengths and fibre counts, or LC duplex patch cords for short links.
