Cable tester upgrade FIBERcat Test & Talk is a performance upgrade option for LANcat cable testers. Test & Talk certifies multimode fiber in pairs by comparing 850/1300 nm loss, length and propagation delay measurements against industry standards, and by providing interpretation-free pass/fail results. The modules include an integrated two-way talk set that lets operators at opposite ends of the link communicate without two-way
