Handheld detector identifies live fibres
The LFD-203 is a live fibre detector for ribbon fibre applications in the field.
The LFD-203 is a live fibre detector for ribbon fibre applications in the field This rugged handheld instrument, which uses nondestructive, macro-bending technology to detect whether or not a signal is being transmitted through an optical fibre, eliminates the possibility of service interruption by inducing attenuation of less than 2dB at 1550nm while identifying all fibres in a ribbon

Chromatic dispersion can be characterised with high accuracy from a single fibre end and testing polarisation mode dispersion from a single end is also possible.
Once a field technician clamps the LFD-203 onto a fibre, the unit displays if there is a signal, a low-frequency modulated tone (270, 1000 or 2000Hz), or if there is traffic and in which direction it is headed.
This data is essential for carrying out installation, maintenance, rerouting or restoration duties on an optical link.
The next-generation LFD-203 comes equipped with a hold button for hands-free operation, a lid to protect the light-emitting diode (LED) from ambient light and displaying false readings, as well as a storage compartment in the handle for interchangeable adapter heads.
One head is dedicated to 2-, 4-, 6-, 8-, and 12-count bare ribbon fibre, while another is designed for 2-, 4-, 6-, 8-, and 12-count jacketed ribbon fibre.
EXFO's LFD-203 also readily detects optical signals on standard 3mm jacketed fibre.
"Ribbon fibre testing has proven to be quite problematic over the years since most instruments can merely detect fibres at the center of a ribbon", said Etienne Gagnon, Director of Product Management at EXFO.
"Our live fibre detector, however, is the only solution on the market today that can identify all fibres on a ribbon with the utmost accuracy and repeatability".
