ShenZhenProduct Overview:
The 25G SFP28 LR is a high-performance, hot-pluggable optical transceiver designed for 25 Gigabit Ethernet applications. Operating at 1310nm wavelength, this module supports transmission distances up to 10 kilometers over single-mode fiber (SMF), making it ideal for long-reach data center interconnects and telecommunications networks.
This reliable and cost-effective solution enables smooth migration from 10G to 25G networks. The module is particularly suitable for 25G Ethernet, cloud computing, and 5G fronthaul applications requiring stable, long-distance connectivity.
Key Features:
Q1: What is a 25G SFP28 transceiver?

ER (Extended Reach) – Up to 40km over SMF
Copper (DAC/AOC) – Short-distance direct attach solutions
Q6: What are the typical applications of 25G SFP28 transceivers?
A6: Data center spine-leaf architecture
5G fronthaul/midhaul networks
High-performance computing (HPC) clusters
Enterprise network upgrades from 10G to 25G
Q7: What is the wavelength of a 25G SFP28 LR transceiver?
A7: The 25G SFP28 LR module typically operates at 1310nm wavelength, optimized for single-mode fiber (SMF) transmissions up to 10km.
Q8: How does 25G SFP28 compare to 100G QSFP28 in cost and performance?
A8: 25G SFP28 is more cost-effective for short-to-medium distances (≤10km), while 100G QSFP28 suits high-density 100G deployments.
Q9: Do 25G SFP28 modules support DDM/DOM monitoring?
A9: Yes, most MSA-compliant modules include Digital Diagnostics Monitoring (DDM/DOM) for real-time performance tracking.
Q10: What’s the future of 25G SFP28 with 50G/100G adoption?
A10: 25G remains relevant for cost-sensitive upgrades, especially in 5G fronthaul and enterprise edge networks, despite higher-speed alternatives.
