100G transceivers are high-speed optical modules that operate over various wavelengths depending on their type and application. Here is a simple overview of the most common transceiver types and their wavelengths:
| SKU | Wavelength | Reach | Channels |
|---|---|---|---|
| 100GBASE-SR4 | 4 x 850 nm over parallel Multi-Mode fibers | Short Range (up to 100 m over MMF) | 4 (25 Gbps each) |
| 100GBASE-CWDM4 | 4 CWDM wavelengths (1295 nm, 1300 nm, 1305 nm, 1310 nm) | Moderate Range (up to 2 km over SMF) | 4 (25 Gbps each) |
| 100GBASE-LR4 | 4 CWDM wavelengths (1295 nm, 1300 nm, 1305 nm, 1310 nm) | Long Range (up to 10 km over SMF) | 4 (25 Gbps each) |
| 100GBASE-ER4 | 4 CWDM wavelengths (1295 nm, 1300 nm, 1305 nm, 1310 nm) | Extended Range (up to 40 km over SMF) | 4 (25 Gbps each) |
| 100GBASE-PSM4 | 1310 nm | Parallel Single-Mode (up to 500m over SMF) | 4 (25 Gbps each) |
| 100GBASE-DR | 1310 nm | Long Reach (up to 500 m over SMF) | 1 (100 Gbps) |
| 100GBASE-FR | 1310 nm | Intermediate Reach (up to 2 km over SMF) | 1 (100 Gbps) |
| 100GBASE-LR | 1310 nm | Long Reach (up to 10 km over SMF) | 1 (100 Gbps) |
