A single-mode fiber optic SFP (Small Form-factor Pluggable) interface is a hot-swappable optical transceiver designed for long-distance, high-speed data transmission over single-mode fiber.OverviewA s...
A single-mode SFP transceiver converts electrical signals from network devices into optical signals for transmission over single-mode fiber (SMF) and vice versa, enabling long-distance communication with minimal signal loss . These modules are widely used in switches, routers, servers, and media converters for Ethernet, Fibre Channel, and telecom applications .
| Feature | Single-Mode SFP | Multimode SFP |
|---|---|---|
| Fiber Core | 9 µm | 50–62.5 µm |
| Wavelength | 1310/1550 nm | 850 nm |
| Distance | 2–120 km | 100–550 m |
| Use Case | Long-haul, metro, campus backbone | Short-range, intra-data center |
| Attenuation | Low | Higher over distance |
