This unit
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.Key Features
- Compact, field-hardened design rated for demanding deployment environments
- Multiple duplex and multi-fiber connector compatibility
- Battery operation extends field deployment without AC power dependency
- CoLT-View PC software enables numeric and graphical result visualization
- Data export to MS Excel™ for integration with network documentation workflows
- Hangable soft carrying case included for field portability
Typical Applications
- Insertion loss and link loss measurement during cable plant acceptance testing
- Optical power verification at connector interfaces
- Optical return loss measurement for link quality assessment
- Fiber length determination for documentation and troubleshooting
- DSL local loop verification (ADSL, ADSL 2+, SHDSL, VDSL) and circuit troubleshooting
- Broadband service deployment validation for VDSL2, ADSL2+, and triple-play architectures
- Service level confirmation across installed local loop infrastructure
Compatibility & Integration The CoLT-450 supports standard fiber connector interfaces and both singlemode and multimode fiber types. CoLT-View software integrates measurement results with standard spreadsheet applications, enabling automated reporting and historical data analysis across network deployment projects.

Exfo CoLT-450 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo CoLT-450. Calibration covers distance accuracy verified against a calibrated fiber length reference, event loss measurement accuracy at splice and connector events, dead zone (event and attenuation) at rated pulse width, dynamic range verification at 1310 nm and 1550 nm, backscatter coefficient calibration, and return loss measurement accuracy. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Exfo CoLT-450 faults: optical port connector damage or contamination, battery failure, display damage from field use, module failure on FTB or MTS platforms, calibration drift. Most field OTDRs fail due to physical damage. On modular platforms (EXFO FTB, Viavi MTS), individual module failures are serviced without replacing the entire mainframe. Optical port cleaning resolves many apparent measurement faults before mechanical repair is needed.
