The EXFO FTB-1400 Multitest Module is a modular optical testing instrument designed for integration with EXFO’s FTB-300 and FTB-400 platforms. It consolidates power measurement, light sourcing, visual fault location, fiber identification, and digital voice communication into a single unit for metro and long-haul network testing. Note: This module was discontinued January 1, 2006, with end-of-service January 1, 2011; current availability typically involves refurbished or pre-owned equipment.
