10G 10GBASE-LR Optical SFP+ Module for Single-Mode Fiber, 2SM, LC Duplex, 20 km, 1310 nm, DOM

The 10G 10GBASE-LR Optical SFP+ Module is designed for high-speed data transmission of up to 10 Gbps over dual single-mode optical fiber (2SM). Compliant with the 10GBASE-LR standard, the module operates at a wavelength of 1310 nm and provides reliable communication over distances of up to 20 km.

The transceiver features a standard LC Duplex optical interface, using one fiber for data transmission and the other for data reception. It is an ideal solution for enterprise networks, backbone fiber links, data centers, telecommunications infrastructure, and other high-performance optical communication systems.

Support for DOM (Digital Optical Monitoring) enables real-time monitoring of the transceiver's operating parameters, including temperature, supply voltage, laser bias current, transmit optical power, and receive optical power. This simplifies network diagnostics, preventive maintenance, and troubleshooting.

Key Features

• Data rates up to 10 Gbps for 10 Gigabit Ethernet applications.
• Transmission distance up to 20 km over single-mode fiber.
• Dual-fiber (2SM) operation with dedicated transmit and receive fibers.
• LC Duplex optical connector for reliable fiber connectivity.
• 1310 nm operating wavelength compliant with the 10GBASE-LR standard.
• Digital Optical Monitoring (DOM) for continuous diagnostics.
• Hot Swap support for installation and replacement without powering down compatible equipment.
• MSA compliant, ensuring compatibility with a wide range of networking devices.

How It Works

The optical transceiver converts electrical signals generated by networking equipment into optical signals for transmission over single-mode fiber. A compatible SFP+ module at the opposite end converts the received optical signal back into an electrical signal.

The connection requires two single-mode optical fibers:

• one fiber for transmitting data (TX);
• one fiber for receiving data (RX).

For proper operation, compatible 10GBASE-LR SFP+ modules operating at 1310 nm should be installed at both ends of the optical link.

Digital Optical Monitoring (DOM)

DOM continuously monitors the operating condition of the optical transceiver through supported networking equipment.

Depending on device capabilities, the following parameters can be monitored:

• module temperature;
• supply voltage;
• laser bias current;
• transmit optical power (TX Power);
• receive optical power (RX Power).

DOM helps identify signal degradation, monitor optical link performance, and significantly reduce troubleshooting time.

Applications

• 10 Gigabit Ethernet networks;
• backbone fiber optic links;
• enterprise LANs;
• data centers;
• server rooms;
• telecommunication networks;
• high-speed storage area networks (SAN);
• switch, router, server, and media converter interconnections.
