Live Fiber Monitoring in CWDM Networks

To cope with the significant increase for storage and on-demand delivery of digital content, enterprises need to boost their optical-pipe capacity. Most turn to coarse wavelength-division multiplexing (CWDM) and dense wavelength-division multiplexing (DWDM) to scale up and avoid installing new fiber. Whether they are planning to lease this extra capacity or use it themselves, someone […]

FTTH PON Testing Overview

Proper testing is a critical part of installing, activating and maintaining a PON. While most components are tested during the manufacturing process, they are tested again after splicing and installation of splitters and access terminals. Field testing is required to ensure no excess loss or reflectance has been introduced due to micro-bends in installed fiber, […]

Optical fiber type mismatch problem when using OTDR

OTDR (Optical time-domain reflectometer) is traditional fiber optic test equipment used to characterize fiber optic. It is most easy to use but the OTDR is also one of the most expensive instrument, OTDR could give you an overview of fiber cable link characterstic of the whole system you test. OTDR is applied for estimating the […]

Troubleshooting Fiber Installations using the TLOT730 OTDR

The TLOT-730 OTDR is used to identify cable length and cable fault point or loss events of a fiber optic cable or link. This is mandatory during the installation/fiber acceptance test processes and also during troubleshooting tasks. This application note will provide the beginners with details concerning typical measurements of optical fibers for PON (passive […]
