OPM-50 Intelligent Optical Power Meter with  automatic wavelength identification, Remote reference value setting, compatible with FTTx tests.

Product Description

Automatic Wavelength Identification:

Compatible with the digital encryption protocols of SLS-50, OPM-50 can automatically identify the wavelength of the optical signals transmitted from SLS-50 and switch to the corresponding test mode, which greatly reduces the workload at both ends and avoids potential error.

Remote Reference Value Setting:

OPM-50 can receive the power parameters of digital-encrypted signal transmitted from SLS-50 as reference for precise link loss measurement even the two units are far apart.

Internal Clock & Fiber S/N Editable:

Internal clock enables OPM-50 to save test data with time and editable fiber SN information.

Compatible with FTTx Test:

OPM-50 can be applied to measure Triple-play signals (1310nm, 1490nm and 1550nm) on Passive Optical Network (PON).
