1310/1550 FBT WDM Based on the technology of fused tapering, PHX can provide low loss, high-reliability wavelength split multiplexers (WDM), which can pass the reliability test standard of Telcordia GR1221. Wavelength-division multiplex couplers can provide common working wavelengths, such as 980/1550nm, 1480/1550nm, 1310/1550nm, etc., used in fiber amplifiers and communication equipment.

TWH-P2020 is a handheld instrument with an integrated FTTx/PON optical power test, which is suitable for the acceptance, activation, and maintenance of BPON, EPON, and GPON. It can test the optical power of 1490nm, 1550nm, and 1310nm at any position in the PON network at the same time, and has a threshold setting function to determine the optical power "pass/fail" in the optical fiber and improve the network judgment time. The TWH-P2020 series also integrates the functions of OPM or VFL. And it has multiple functions. Color screen design, high definition, suitable for working in a variety of light environments. Hand-held design, lightweight, small size, long standby time, simple operation.
