Light sources perform a variety of functions. While some fall under the multi-purpose category, providing automated features, others are optimized for specific tasks such as detecting faults, breaks and microbends in the fibre. The key is choosing the right light source for the job.

Power meters are part of the toolbox essentials for all technicians installing or maintaining any type of fibre networks. There are general-purpose power meters, semi-automated ones, as well as power meters optimized for certain types of networks, such as FTTx or LAN/WAN architectures. It’s a matter of choosing the right gear for the need.

It's a fact: dirty and/or damaged fibre connectors are one of the most common cause of optical network problems. And in today's context where operators must speed up their fibre deployment and operate under amplified OPEX pressure, any network failure prevented can make a difference.

Whether you are working with single-fibre or multifibre connectors, including MPO and MTP™, or with various infrastructures (FTTx, FTTA, DAS and small cells or data centers),  proper connector inspection is an essential best practice for fibre testing and installation, which must be included in all daily workflow procedures.

EXFO's automated and intelligent fibre inspection solutions are designed to speed up and simplify this critical step to any fibre testing and help you deploy faster, more reliable fibre networks.

Turn your Android™ or iOS device into a fully automated fibre inspection solution delivering fast and consistent test results. With no wires in your way or cumbersome battery pack, it provides unmatched end-user experience, combined with bring-it-anywhere portability.

Performing network upgrades or optical testing requires a fibre to be disconnected. Live fibre detection allows to accurately detect traffic and measure signals anywhere on singlemode fibre, without having to disconnect it.

Pinpointing Live and Dark Fibres: Guesswork Ends Here

Performing network upgrade or optical testing requires a fibre to be disconnected. This is often easier said than done, since finding the right connection can be tricky, namely because of fibre mislabelling or poor record keeping. While the dark fibre can be identified using a tone generator (270 Hz, 1 kHz, 2 kHz), the live fibre identification technique often involves one technician pulling one end of the patchcord, with another technician trying to identify which patchcord is moving at the other end—a process that translates into long delays and can result in unnecessary service disruption.

Combined with the TG-300B Tone Generator, the innovative LFD-300B FiberFinder™ Live Fibre Identifier enables technicians to identify a specific live fibre without having to disconnect it and, above all, without having to guess.

This brings key benefits:

  • No more network outages as a result of fibre detection/identification procedures

  • The minimized need to access the network helps prevent errors
