Optical transceivers convert electrical signals to optical signals for fiber optic communication. The right choice depends on your speed, distance, and switch compatibility requirements.
Quick Recommendation
| Need | Best fit | Why it fits |
|---|---|---|
| 100G data center interconnect | XS-OP-100G-QSFP28-SR4 | 100G QSFP28 for short-reach data center links up to 100m. |
| 400G spine/core | XS-OP-400G-QSFP-DD-SR8 | 400G QSFP-DD for high-bandwidth spine and core links. |
| 25G access layer | XS-OP-25G-SFP28-SR | 25G SFP28 for modern access layer connections. |
