EXFO's ELS-50 Light Source provides excellent stability and high measurement accuracy for up to three singlemode wavelengths (1310, 1490 and 1550 nm) or two multimode wavelengths (850 and 1300 nm). It is the perfect complement to the FiberBasix 50 EPM-50 Power Meter when it comes to measuring attenuation on fiber-optic links.

• Easy-to-use interface for error-free testing
• Interchangeable connectors, for first-class flexibility
• Cost-effective, rugged and highly reliable Ideal for testing and troubleshooting optical premises networks
• Available as stand-alone units or in all-in-one test kits including all required accessories (adapters, carrying case, etc.)
• Five test kits designed for specific users/testing needs: LAN, outside plant, contractors, FTTH and CATV
