Fiber optic power meter
Fiber optic power meter PM23 is used for measurement of output power of optical front-ends and fiber nodes, the fiber power meter can also test the insertion loss of the passive fiber optic components in the networks.

Fiber optic light source
Fiber optic light source LS25 provides one or two wavelength stable laser output by using semiconductor laser diode module incorporated with back facet monitoring photo diode. This fiber optic light sources high stability of laser output power is achieved with the help of advanced feedback control.
