Are there 10 Gigabit single-mode optical modules available

Yes, 10 Gigabit single-mode optical modules are available, supporting distances up to 10 km and including both standard duplex and BiDi (single-fiber) options.

Standard Single-

Mode SFP+ Modules10GBASE-LR SFP+ modules are designed for single-mode fiber (SMF) and can support link distances up to 10 km using duplex LC connectors. These modules are compatible with major brands like Cisco, HP, and Brocade, and operate at high speeds up to 10. 31 Gbps while maintaining low power consumption.

They are suitable for both LAN and MAN networks, providing reliable long-distance connectivity over single-mode fiber.

Bi

Di (Bidirectional) Single-Mode Modules10G BiDi SFP+ modules allow full-duplex communication over a single fiber strand using Wavelength Division Multiplexing (WDM). This technology uses two different wavelengths to separate transmit and receive signals, effectively halving fiber usage while maintaining 10G speeds.

Bi

Di modules typically support distances up to 10 km, integrate DFB lasers and PIN photodiodes, and are hot-swappable and standards-compliant with SFP+ MSA, CPRI, and eCPRI protocols. They are ideal for fiber-constrained environments or high-density deployments.

Key Features

Speed: Up to 10–11. 3 GbpsDistance: Up to 10 km on single-mode fiberConnector Type: Duplex LC for standard modules, simplex LC for BiDi modulesPower Consumption: Typically ≤1 WCompatibility: Works with a wide range of switches and NICs from major vendorsDeployment Benefits: BiDi modules reduce fiber usage, simplify cabling, and lower installation costs SummaryWhether you need traditional duplex 10G single-mode modules for standard long-distance links or BiDi modules for single-fiber full-duplex applications, there are multiple options available that support 10G speeds over single-mode fiber up to 10 km. These modules are widely used in enterprise, data center, and telecom networks to optimize fiber infrastructure and maintain high-speed connectivity.
