25G SFP28 Overview
The 25G SFP28 category contains two optical transceiver modules for 25G Ethernet, telecommunications, and data center connections. Both models use the SFP28 form factor, duplex LC/UPC connectors, and DOM monitoring, and each module is individually tested on its target switch. The transceivers comply with the SFP28 MSA, RoHS, CPRI, and eCPRI standards. The series includes one multimode SR transceiver and one single-mode LR transceiver, covering transmission distances from 100m to 10km. Both modules support 25G links while maintaining a compact, low-power interface.
| Model | Form Factor | Fiber Type | Data Rate | Max. Reach | Connector |
|---|---|---|---|---|---|
| SFP-25G-SR | SFP28 | MMF | 25G | 100m | Duplex LC UPC |
| SFP-25G-LR | SFP28 | SMF | 25G | 10km | Duplex LC UPC |
FAQ
What is the main optical difference between the SFP-25G-SR and SFP-25G-LR transceiver modules?
The SFP-25G-SR uses 850nm multimode transmission for links up to 100m, while the SFP-25G-LR uses 1310nm single-mode transmission for links up to 10km. Both use the SFP28 form factor and duplex LC/UPC connectors.
What fiber and connector are required to deploy the SFP-25G-SR over a 25G link?
A duplex LC/UPC multimode fiber connection is required. The SFP-25G-SR operates at 850nm and supports 25GBASE-SR transmission distances up to 100m.
Can the SFP-25G-LR provide a 25G connection over a distance of 10km?
Yes. The SFP-25G-LR supports 25GBASE-LR links up to 10km over single-mode fiber. It operates at 1310nm and uses a duplex LC/UPC optical interface.
Can the SFP-25G-SR and SFP-25G-LR use the same type of fiber patch cable?
No. The SFP-25G-SR requires multimode fiber, while the SFP-25G-LR requires single-mode fiber. Both use duplex LC/UPC connectors, but the fiber type must match the selected transceiver.
Which network protocols are supported by the SFP-25G-SR and SFP-25G-LR modules?
Both models support 25G Ethernet, CPRI, and eCPRI connections. They can be deployed for compatible telecommunications and data center links that require an SFP28 optical interface.
Do the SFP-25G-SR and SFP-25G-LR include digital optical monitoring?
Yes. Both the SFP-25G-SR and SFP-25G-LR include DOM functionality, allowing compatible host equipment to monitor the operating status of the optical transceiver.
Are the SFP-25G-SR and SFP-25G-LR compliant with the SFP28 MSA and RoHS requirements?
Yes. Both models comply with the SFP28 MSA and RoHS requirements. They share the standardized SFP28 form factor while providing different optical reaches and fiber types.
Are the SFP-25G-SR and SFP-25G-LR tested with their intended target switches?
Yes. Each SFP-25G-SR and SFP-25G-LR module is individually tested on its target switch to verify operation with the intended platform.
