10 Gigabit Single-Mode Fiber SFP

10G SFP+ modules support single-mode fiber with distances up to 10 km using standard duplex LC connectors or over a single strand using BiDi technology.

Standard Single-

Mode 10G SFP+ ModulesStandard single-mode 10G SFP+ transceivers use duplex LC connectors and operate at 1310 nm wavelength, supporting distances typically up to 10 km at 10 Gbps. These modules are compatible with MSA-compliant SFP+ slots on switches and fiber converters, providing reliable long-distance connectivity for enterprise, campus, and data center networks. They are hot-pluggable and support high-speed data rates up to 10.

31 Gbps while maintaining low power consumption and immunity to electromagnetic interference (TRENDnet, Black Box).

Bi

Di (Bidirectional) 10G SFP+ ModulesBiDi SFP+ modules enable full-duplex communication over a single strand of single-mode fiber using wavelength division multiplexing (WDM). One wavelength is used for transmitting data and another for receiving, typically 1270 nm / 1330 nm. These modules require matched pairs at each end of the link and use a simplex LC connector, effectively reducing fiber usage by 50% compared to traditional duplex SFP+ optics.

Bi

Di modules support distances commonly up to 10 km, with some models extending to 20 km or 40 km depending on the transceiver type. They are ideal for fiber-constrained environments, metro networks, and data center interconnects (FS, L-com).

Key Considerations

Connector Type: Standard duplex LC for traditional single-mode SFP+, simplex LC for BiDi modules. Wavelengths: 1310 nm for standard single-mode; 1270/1330 nm for BiDi. Distance: Up to 10 km for most single-mode SFP+ modules; longer distances possible with specialized BiDi modules.

Compatibility: Ensure SFP+ modules are MSA-compliant and compatible with the switch or device vendor. Deployment: BiDi modules must be installed in complementary pairs to establish a link; standard duplex modules require two fibers per link.

Summary

For 10G single-mode fiber deployments, you can choose between: Standard duplex SFP+ modules for straightforward 10 km links using two fibers.

Bi

Di SFP+ modules for single-fiber links, reducing cabling complexity and fiber usage while maintaining full-duplex 10G performance. Both options support high-speed 10G Ethernet, are hot-swappable, and are suitable for enterprise, campus, and data center applications.
