FAQ About 10G CWDM SFP+ Transceiver
A 10G CWDM SFP+ transceiver is a hot-swappable optical module that enables 10 Gigabit Ethernet transmission over single-mode fiber using Coarse Wavelength Division Multiplexing (CWDM) technology. Unlike traditional 10G modules that typically use fixed wavelengths, CWDM transceivers support multiple wavelengths (1270nm–1610nm), allowing multiple signals to be transmitted over a single fiber, reducing infrastructure costs.
Ensure your switch or router has a standard SFP+ slot and use duplex LC single-mode fiber cables. The duplex LC interface delivers reliable bi-directional connectivity and allows hot-swapping without extra adapters.
Yes, the 10G CWDM SFP+ transceiver 100km model is designed for long-haul applications, providing reliable data transmission up to 100 kilometers over single-mode fiber. It’s ideal for metropolitan area networks (MANs), telecom backhaul, and long-distance enterprise interconnects.
When selecting a CWDM 10G SFP+ transceiver, consider key factors such as required distance, wavelength compatibility, and fiber type. Ensure the transceiver supports the correct CWDM wavelength and reach for your application (e.g., 10km, 40km, or 80km), and verify that it is compatible with your switch or router.
