Insertion Return Loss tester

The insertion return loss tester new design point:

The insertion return loss tester can show two wavelength on one time, and two wavelengths' insertion loss and return loss all can be show at the same time.

The insertion Return Loss tester has unique insertion loss warning tip

The Insertion Return Loss tester is large colored LCD display

Insertion Return Loss tester is high precision, wide measurement range

Insertion Return Loss tester General
HK-8S insertionn return loss tester is widely applied in the test of Insertion loss and return Loss in fiber optic cable, optical passive components and fiber optic communications system.

The Insertion Return Loss tester unique insertion loss warning setting, different display colors to increase testing efficiency

Linkage of the wavelength of the modes of optical light source and optical power meter, reducing operation procedure
Easy to clean with dismountable design adaptors
