FAQ About 25G SFP28 LR Optical Transceiver
The normal service life can reach 5-10 years, depending on the use environment and workload.
Yes, most 25G LR modules are available in versions compatible with major switch brands like Cisco, Juniper, Arista, and Dell. Always ensure you’re using a vendor-compatible 25G SFP28 LR transceiver for optimal performance and support.
The 25G LR module is designed to work with OS2 single-mode fiber and uses a standard LC duplex connector. It’s important to use LC fiber cables for 25G SFP28 LR modules to ensure minimal signal loss.
Yes, all SFP28 modules, including the LR variant, support hot-swapping. This allows you to replace or install the hot-swappable 25G LR optical transceiver without shutting down your network device.
A standard 25G LR module consumes around 1W of power, depending on the brand and internal components. For energy-sensitive environments, choose a low-power 25G SFP28 LR transceiver with efficient thermal management.
The 25G LR transceiver supports up to 10 kilometers of transmission over single-mode fiber, making it ideal for long-reach applications. It’s commonly used as a 10km 25G SFP28 long reach optical transceiver in campus and metro networks.
