In-Service OTDR Fiber Monitoring (RFTS) Solutions

Challenges

Four pain points of cable O&M

Slow fault localization

After a fiber cut, crews carry an OTDR to locate the break section by section — long repair cycles and growing business-interruption losses.

Degradation invisible

Bending, crushing and water ingress degrade gradually; traditional O&M only responds after the fiber breaks.

No asset inventory

Long cable routes are complex; joints and loss points lack an online ledger, so fault diagnosis has no data to rely on.

Multi-owner complexity

Cable assets belong to many owners (carriers, private networks, self-built); O&M responsibility needs objective monitoring data.

Solution Architecture

Architecture: 24/7 automatic monitoring loop

Monitor → localize → archive: a closed loop that upgrades cable O&M from firefighting to prevention.

Monitoring · RFTS

In-Service OTDR Fiber Monitoring (RFTS)

The RFTS unit automatically patrols in-service fiber 24/7 — 100 km range (industry avg 80 km), real-time attenuation curve and event-point tracking for the full route.

Localization · ±1 m

±1 m fault location

±1 m on the fiber-link coordinate plus ±5 m field location (using cable route records) guides repair crews straight to the real fault point — no section-by-section search.

Ledger · Health archive

Fiber health archive

Continuous attenuation-curve accumulation builds an online ledger of joints, loss points and degradation trends, turning O&M from after-the-fact repair to before-degradation warning.

FAQ

Frequently Asked Questions

Traditional OTDR testing needs a technician on site, section by section — a reactive check. In-Service OTDR Fiber Monitoring (RFTS) delivers 24/7 automatic monitoring with ±1 m fault location and second-level alarms, shifting O&M from repair to prevention.

No. Monitoring uses a spare core or a non-disruptive access method, physically isolated from live traffic; sensing-communication fusion allows one core for both.

±1 m is the location accuracy on the cable-route coordinate; ±5 m is the accuracy mapped to the actual ground position. Together they guide crews straight to the fault point.

Yes. The solution is owner-agnostic: transport private networks, power communication networks, petrochemical private networks, and campus/factory self-built cable all apply, whenever you need data-communication quality and fiber health visibility.
