GN Nettest CMA-4500 OTDR Module

The GN Nettest/Photonetics CMA-4500-006 is a type of optical time domain reflectometer (OTDR). It is used to test and troubleshoot fiber optic cables. It sends a pulse of light down the fiber and measures the reflections. This allows technicians to identify breaks, splices, and other imperfections in the cable.

This unit

The GN Nettest/Photonetics CMA-4500-006 is a specialized piece of telecommunications test equipment used for characterizing optical fibers. As an OTDR (Optical Time Domain Reflectometer), its primary function involves injecting a high-powered light pulse into the fiber under test and analyzing the backscattered light or reflections that return to the instrument. By carefully measuring the time of flight and amplitude of these reflections, the OTDR can precisely determine the location and severity of various events along the fiber, such as splices, connectors, bends, and breaks. This information is crucial for installation, maintenance, and troubleshooting of optical networks.

GN Nettest/Photonetics CMA-4500-006 — Repair & Calibration Service

Aumictech offers NIST-traceable calibration and repair for the GN Nettest/Photonetics CMA-4500-006. Calibration covers distance accuracy verified against a calibrated fiber length reference, event loss measurement accuracy at splice and connector events, dead zone (event and attenuation) at rated pulse width, dynamic range verification at 1310 nm and 1550 nm, backscatter coefficient calibration, and return loss measurement accuracy. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.

Common GN Nettest/Photonetics CMA-4500-006 faults: optical port connector damage or contamination, battery failure, display damage from field use, module failure on FTB or MTS platforms, calibration drift. Most field OTDRs fail due to physical damage. On modular platforms (EXFO FTB, Viavi MTS), individual module failures are serviced without replacing the entire mainframe. Optical port cleaning resolves many apparent measurement faults before mechanical repair is needed.

GN Nettest/Photonetics CMA-4500-006 calibration cost

NIST-traceable calibration for the GN Nettest/Photonetics CMA-4500-006 is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument covers distance accuracy verified against a calibrated fiber length reference, event loss measurement accuracy at splice and connector events, dead zone (event and attenuation) at rated pulse width, dynamic range verification at 1310 nm and 1550 nm, backscatter coefficient calibration, and return loss measurement accuracy. Turnaround is 1 to 3 business days after receipt. See full calibration details →
