The EXFO CoLT-450 is a compact and rugged optical loss test set engineered for field deployment of fiber optic networks. It delivers accurate insertion loss, link loss, and optical power measurements across singlemode and multimode fiber installations. The instrument supports optical return loss measurement and fiber length determination, making it essential for field technicians validating cable plant performance and troubleshooting transmission circuits.
Technical Specifications
The CoLT-450 operates on 120V power with battery operation capability for mobile field work. It measures insertion loss, link loss, optical power, and optical return loss across supported fiber types. Fiber length measurement and multimode/singlemode fiber support enable comprehensive cable plant validation.
