Viavi COSA-4055 (2301/02)

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. Housed in a T-BERD/MTS-2000, -4000 V2, -5800 or OneAdvisor-800 platform, the VIAVI COSA-4055 is the ideal handheld CWDM analyzer for field service groups to install, maintain, and upgrade CWDM systems.
