  • Page 6: Introducing The Cosa-4055 Module

    BN 2301/02 Fig. 1 Two versions of the COSA-4055 modules The COSA-4055 is Viavi’s new generation of CWDM analyzer modules. It scans the full wavelength range between 1260 and 1625 nm for commissioning, upgrade, and trouble shooting of CWDM networks. The COSA-4055 offers the functionality and speed of an optical spectrum analyzer in a handheld form at a fraction of the price of an OSA.

  • Page 7: Sfp Slots

    Chapter 1 Optical Spectrum Measurement Safety information The COSA-4055 comes in two versions. The basic version (BN 2301/01) provides CWDM analyzer functionality only. The advanced version (BN 2301/02) additionally offers 2 integrated SFP slots for mounting up to 2 SFP transceiver modules (to be ordered separately). The transceiver modules can be used as a CWDM stimulus to check CWDM networks together with the CWDM analyzer.

     Never look directly into the output of a laser source or into an optical fiber connected to it.  Always cover unused ports.  Heed the normal precautions for working with laser radiation and consider local regulations. MTS / T-BERD 5800 • COSA-4055 • User Manual 2016.01...

  • Page 9: Specific Laser Safety

    However, the user is free to use any other SFP transceiver compatible with the SFP Multi Source Agreement (MSA). CAUTION  In this case you must observe the laser classification of the inserted SFP transceiver and its safety instructions! MTS / T-BERD 5800 • COSA-4055 • User Manual 2016.01...
