What is the maximum distance for fiber without a repeater?

Single-mode fiber supports distances up to 80–100 km without amplification for standard transceivers, and longer distances with EDFA amplifiers or DWDM systems.

How do you test fiber quality after installation?

Every splice and end-to-end link is tested with an OTDR to measure attenuation and verify splice loss is within specification. We provide all OTDR traces as part of the handover pack.

Can you install fiber for SCADA and protection in a Substation?

Yes — Substation fiber for SCADA, protection teleprotection and inter-panel communication is a specialist area and we have experience delivering these systems to IEC 61850 and utility requirements.
