Why coherent OTDR
Amplified links change
the measurement problem.
Conventional OTDR methods cannot simply see through every optical amplifier in a transoceanic system. The MW90010B uses coherent detection and a tunable C-band probe to reveal the loss profile of long submarine cables with in-line repeaters.

Recommended operating workflow
01
Baseline
Capture a reference trace for every monitored fibre and wavelength path.
02
Monitor
Compare scheduled or event-triggered measurements against the baseline.
03
Localise
Translate the trace change into a precise distance-to-event diagnosis.
04
Restore
Dispatch with better information, then verify fibre and service performance.
R&D EVIDENCE
Ready for the next fibre architecture.
Anritsu and KDDI Research have demonstrated remote diagnosis of multicore optical-fibre cable in a simulated environment using the MW90010B to visualise fault location, loss profile and inter-core crosstalk. This is emerging research evidence—not a claim of standard deployed functionality.
CoTDR knowledge centre
Anritsu MW90010B &
submarine cable testing.
Technical guidance for Malaysian submarine network operators, landing stations, cable owners and maintenance teams evaluating coherent optical time domain reflectometry.
What is a Coherent OTDR (CoTDR)?
A Coherent Optical Time Domain Reflectometer uses coherent detection to measure long optical-fibre links. It is suited to submarine cable testing where in-line optical amplifier repeaters make conventional OTDR measurement difficult.
What does the Anritsu MW90010B measure?
The Anritsu Coherent OTDR MW90010B supports submarine fibre fault location, cable-loss profiling, bending-loss investigation and fibre-length measurement across amplified long-haul links.
How far can the MW90010B test?
The standard measurement range is up to 12,000 km. Option MW90010B-003 extends the specified maximum range to 20,000 km, subject to fibre, repeater spacing and measurement conditions.
Where can I source Anritsu CoTDR in Malaysia?
AMS Extreme supplies and supports Anritsu MW90010B Coherent OTDR solutions in Malaysia for landing-station assurance, submarine fibre optic cable testing, fault localisation and restoration projects.
