0.75 mm Core Black PE Simplex PMMA POF Cable, 2.2 mm OD for Arc Flash Protection
The 0.75 mm core / 2.2 mm outer diameter black PE simplex PMMA POF cable is a step-index plastic optical fiber cable with a polyethylene jacket, built for short-range optical sensing and signal links — including arc flash detection circuits in switchgear, where galvanic isolation and noise immunity matter.
Product Overview
The cable carries a PMMA (polymethyl methacrylate) plastic optical fiber with a fluorinated-polymer cladding, jacketed in black polyethylene. Per the supplier’s product-family table, this 2.2 mm OD / 0.75 mm core simplex version is rated at ≤0.25 dB/km attenuation and is supplied on 1000 m rolls. The black PE jacket stays flexible and durable for cabinet and field routing.
POF carries light, not power or control voltage. In an arc flash protection system the fiber links the optical sensing head to the protection relay, giving complete galvanic isolation from switchgear voltages and immunity to the electromagnetic noise that troubles copper sensing loops.
Key Features
- PMMA step-index POF, 0.75 mm core inside a 2.2 mm black PE jacket.
- Flexible, lightweight simplex cable — easy to route along busbars and inside switchgear compartments.
- Supplier family rating ≤0.25 dB/km attenuation; supplied on 1000 m rolls, cut to length on request.
- Large acceptance angle (NA ≈ 0.5 family-typical) suits LED-based arc-sensing heads.

Ordering & Customization
We supply this cable by the 1000 m roll or cut to specified lengths with termination on request. To quote, please confirm: roll vs cut length, required connectors (for example TOSLOCK or SMA-style POF), quantity, and the sensing-head interface your arc flash protection device uses. Contact our sales team with your layout.
FAQ
Is this cable certified for arc flash protection? The cable itself is a passive POF medium. Supplier listings state RoHS/REACH/CE and ISO9001 manufacturing certifications, but protection performance depends on the complete detection system and relay design — we do not claim system-level arc flash certification.
Why choose 0.75 mm core instead of 1.0 mm? The smaller 0.75 mm core version fits sensing heads specified for that fiber size; match the fiber to your detector head, and confirm termination compatibility before ordering.
How far can the signal travel? With ≤0.25 dB/km attenuation, typical switchgear sensing loops run well under 100 m; always design to your protection device’s optical budget.
What can the ends be terminated with? Cut lengths can be fitted with common POF connectors such as TOSLOCK or SMA-style POF — specify on enquiry.
