Alistar 10G 10GBASE-SR Optical SFP+ Module for Multi-Mode Fiber, 2MM, LC Duplex, 300 m, 850 nm, DDM

The Alistar 10G 10GBASE-SR Optical SFP+ Module is designed for high-speed data transmission at up to 10 Gbps over dual multi-mode optical fiber (2MM). Compliant with the 10GBASE-SR standard, the module operates at a wavelength of 850 nm and provides reliable communication over distances of up to 300 meters.

The transceiver features a standard LC Duplex optical interface, using one fiber for transmission and the other for reception. It is an ideal solution for connecting switches, routers, servers, storage systems, and other networking equipment in enterprise networks, server rooms, and data centers.

Support for DDM (Digital Diagnostic Monitoring) enables real-time monitoring of the transceiver's operating parameters through compatible networking equipment. 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 300 meters over multi-mode fiber.
• Dual-fiber (2MM) operation with dedicated transmit and receive fibers.
• LC Duplex optical connector for reliable fiber connectivity.
• 850 nm operating wavelength compliant with the 10GBASE-SR standard.
• Digital Diagnostic Monitoring (DDM) for continuous transceiver diagnostics.
• Hot Swap support for installation and replacement without shutting down compatible equipment.
• MSA compliant, ensuring broad compatibility with networking devices from various manufacturers.

How It Works

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

The connection requires two multi-mode optical fibers:

• one fiber for data transmission (TX);
• one fiber for data reception (RX).

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

Digital Diagnostic Monitoring (DDM)

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

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

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

DDM helps detect signal degradation, monitor optical link performance, and significantly reduce troubleshooting time.

Applications

• 10 Gigabit Ethernet networks;
• enterprise LANs;
• data centers;
• server rooms;
• network switches and routers;
• storage area networks (SAN);
• high-speed backbone connections within buildings;
• high-performance optical communication systems.
