Fibre testing system avoids disruptions

The CWDM OTDR solution was developed to help cable operators, dark fibre providers and telecommunications service providers characterise maintain and troubleshoot CWDM fibre networks.

JDSU has released the coarse wavelength division multiplexing (CWDM) series of OTDR modules for its T-BERD/MTS-8000 and T-BERD/MTS-6000 platforms.

This solution combines several new features into one OTDR test solution for short and medium-haul CWDM network applications.

The CWDM solution complements the existing range of OTDR modules within the T-BERD/MTS family and further enables users to rapidly, reliably and cost-effectively deploy network services in one convenient package.

The CWDM OTDR solution was developed to help cable operators, dark fibre providers and telecommunications service providers characterise maintain and troubleshoot CWDM fibre networks.

Using JDSU's CWDM OTDRs, users can test new wavelength routes not yet in use without disrupting communications traffic on active wavelengths.

This "in-service" capability increases technician productivity and helps reduce installation and maintenance costs.

The JDSU CWDM OTDR solution features a series of multiwavelength OTDR modules compatible with the T-BERD/MTS-6000 and T-BERD/MTS-8000 platforms.

The flexible solution allows for scalability within the user's system, including a dedicated dynamic range for Metro applications that enables optimised trace for all test scenarios.

The solution also includes end-to-end testing through multiplexers and de-multiplexers (displaying all tested wavelengths on one screen), characterisation of the fibre plant for CWDM installations and test capabilities across all fibre lengths.
