Light sources
Light sources simulate the optical voice, video and data signals of real-life service applications, making them an essential component of a thorough testing process. Discover EXFO’s broad range of light-source testing solutions.
PXM/LXM - Duplex and multi-fiber OLTS
The PXM/LXM duplex and multi-fiber optical loss test set (OLTS) provides Tier-1 fiber certification for up to 24 fibers. Measures insertion loss, length and polarity at two wavelengths in 1 second, with patented Click-Out adapters for connector compatibility.
FiberBasix 50 - Handheld testers
FiberBasix 50 is a handheld optical light source and power meter solution for measuring signal attenuation during fiber-optic cable installation. It supports link-loss testing and troubleshooting of optical premises networks.
FLS-140 - Visual fault locator
FLS-140 is a pocket-size visual fault locator (VFL) that uses a 655 nm red laser to trace optical fibers and identify breaks, bends, faulty connectors and splices in singlemode and multimode fibers, with a reach of up to 5 km.
FLS-170 - Visual fault locator (VFL)
FLS-170 is a pocket-sized visual fault locator (VFL) that uses a 650 nm red laser to identify fibers and locate breaks, bends, faulty connectors and splices in singlemode and multimode fibers, with a range of up to 7 km.
FLS-190 - High-power visual fault locator (VFL)
FLS-190 is a pocket-sized, high-power visual fault locator (VFL) that uses a 650 nm red laser to identify faults in optical fibers over distances of up to 12 km. It offers 5 mW output power and flashing or continuous operation modes.
FLS-240 - Visual fault locator
FLS-240 is a handheld visual fault locator (VFL) that uses a 635 nm red laser to identify fiber breaks, bends, faulty connectors and splices. It supports pulsed and continuous-wave operation for fiber tracing and fault location.
FLS-300 - Light source
FLS-300 is a handheld optical light source for fiber link-loss characterization and identification. It supports up to three singlemode wavelengths on one port or four wavelengths (two singlemode and two multimode) on two ports.
FLS-600 - Light source
FLS-600 is a handheld optical light source for fiber link-loss characterization and LAN/WAN certification. Available in laser and LED models, it supports multiple wavelength configurations for singlemode and multimode fiber testing.
FLS-600-NS1548 - Encircled flux compliant light source
The FLS-600-NS1548 is a handheld, encircled flux (EF)-compliant optical light source for Tier-1/2 multimode fiber testing. It provides controlled launch conditions for accurate, repeatable link-loss measurements.
