The cost for huge fiber optic network maintenance is raising up since the popularity of FTTH and development of optical network end users. It is much more harder for operator to manage and maintenance PON network because network access information is incomplete, end users’ information is inaccurate,terminal signal release is incomplete. FCST have professional fiber optic test solution and related products, widely used in FTTH, LAN, metropolitan area optical fiber network, PON network construction, deployment, maintenance, certification and optical communication teaching & scientific research.

When testing with the wavelength of 1310nm, 1490nm, and 1550nm of ordinary OTDR, it is necessary to require that there is no communication light signal in the measured line. Forcibly Live Testing will burn the internal detector of the OTDR. Live testing is when testing, you can stop the light signal in the line, and OTDR can still complete the test.

Light decay generally refers to its luminous flux. When charging the surface of the photosensitive drum, as the charge accumulates on the surface of the photosensitive drum, the potential continues to increase, and finally reaches the "saturation" potential, which is the highest potential.

OTDR (Optical Time Domain Reflectometer) testing plays a crucial role in maintaining and troubleshooting fiber optic networks. To ensure accurate and reliable results, it is important to be aware of common issues that can affect OTDR tests.

Optical Time-Domain Reflectometers (OTDRs) are essential tools for measuring the performance and integrity of optical fiber networks. OTDRs are used to diagnose faults, measure attenuation, and verify the integrity of fiber optic links. However, with so many OTDRs on the market, it can be challengin
