T-BERD/MTS COSA-4055 CWDM Optical Spectrum Analyzer Module
For T-BERD/MTS-2000, -4000 V2, -5800 and OneAdvisor-800 Platforms
The VIAVI Solutions® COSA-4055 module offers a new generation of coarse wavelength division multiplexer (CWDM) analyzers. Until now, large and expensive optical spectrum analyzers (OSA) were used to precisely test wavelength and power levels in CWDM networks, and optical channel checkers were used to verify optical channel presence. The VIAVI COSA-4055 module offers the functionality and speed of an OSA in a handheld form factor at a fraction of the price.
The ITU-T G.695 recommendation promotes vendor interoperability by specifying transmitter/multiplexer characteristics at one end of the CWDM link and the demultiplexer/receiver at the other end. ITU-TG694.2 recommendation specifies the spectral grid for CWDM applications with 18 channels from 1271 to 1611 nm, with a 20 nm channel spacing. To guarantee multivendor compatibility it is important to verify the optical interface parameters according to these recommendations. The COSA-4055 is the ideal tool for checking the critical parameters such as Tx output power and Rx input power and the central wavelengths when installing, commissioning, and troubleshooting CWDM networks as well as for ensuring interface compatibility with different vendors.
Key Benefits
