| Multiple | 10km | 100G | 4x25Gbps channels. There are some extended reach versions that can go 20 or even 30km. |
| ER | EX, ZR (Match channel if you can - mismatch will work without a mux in an emergency, mismatched distance with ZR) | Singlemode | Extended Reach | 1550nm | 40km | 1G/10G |
| They can be baseband, CWDM, or DWDM. "Baseband" is typically a lower tolerance ~1550nm optic that is cheaper and not compatible with DWDM/CWDM channel plans. |
