FRL-30 series optical insertion loss/return loss tester is a high-performance, integrated and intelligent tester for optical fiber network, fiber cable and component manufacturing and laboratory use. Not only can it measure the return loss and determine absolute and relative power value, but also work as a self-testing system measuring optical loss of optical fiber cables and passive devices.
The FRL-30 with three wavelengths of 1310/1490/1550 nm commonly used in FTTx is perfect for
