Exceptional 2km reach on MMF. The 1310nm wavelength is a game-changer for extending our multi-mode links without fiber replacement.
Reliable E-Temp performance. These modules handle our unconditioned cabinet environments perfectly. DOM monitoring is highly accurate.
Solid 1310nm multi-mode link. Perfect for those slightly-too-long runs where standard SX fails. Very dependable hardware.
Impressive temperature tolerance. We've seen no signal degradation even during peak summer heat. A very robust transceiver.
Great 2km reach. Recognized instantly by our Cisco gear. The DOM features provide excellent health data for remote sites.
High-quality extended reach SFP. It solved our distance issues on existing multi-mode fiber perfectly. Highly recommended.
Stable and efficient. These transceivers offer professional-grade reliability for industrial-temp applications. Very happy with the performance.
