The SFP+ module NX_AC_SFP_10G_MM from Softing IT Networks is a network module for use in high-speed networks. It serves as an optical transceiver for multimode fiber cables and enables data transmission at a speed of 10.5 Gbit/s. The module is specifically designed for use in 10GBASE-SR/SW networks as well as in 10G Fiber Channel environments. It features a duplex LC connector, designed for connection with corresponding fiber cables. The operating specification includes a wavelength of 850 nm, typical for multimode systems, and a maximum reach of 400 meters. This reach is suitable for indoor connections in buildings, data centers, or industrial facilities where short to medium distances must be bridged via fiber cables.

SFP+ module is a standard form factor technology for network transceivers, used in switches, routers, and servers. The term SFP+ stands for Small Form-factor Pluggable Plus, describing its compact design and high data throughput performance. The module is designed for use in 10-Gigabit-Ethernet systems (10GBASE-SR) as well as in 10-Gigabit-Fiber-Channel systems (10G Fiber Channel). Compatibility with these standards ensures seamless integration into existing infrastructures.

Multimode fiber is used here, transmitting multiple light modes simultaneously. This allows for higher bandwidth compared to single-mode fibers, although with limited reach. The use of multimode fiber is common in local area networks (LAN) and environments with short connection distances. The wavelength of 850 nm is standard for multimode systems and optimizes signal transmission over the used fiber cables.

10GBASE-SR/SW refers to the Ethernet standardization for 10-Gigabit connections over multimode fiber. SR stands for Short Range, indicating short reach, while SW (Short Wavelength) describes the used wavelength. This specification is part of the IEEE 802.3 standardization and is widely used in modern network infrastructures. The module also supports 10G Fiber Channel, a standard for high-speed connections in storage and server networks.

Duplex LC connector is the physical interface on the module. LC stands for Lucent Connector, a small, robust connector widely used in IT and networking technology. The duplex characteristic means that two fibers (transmit and receive) are connected via a single connector. This is the common configuration for SFP+ modules in multimode systems.

The maximum reach of 400 meters is achieved when using OM3- or OM4-multimode fiber cables. This reach is sufficient for typical applications in buildings, data centers, or industrial environments where cabling spans multiple rooms or floors. The specification refers to the maximum distance that can be transmitted stably at a data rate of 10.5 Gbit/s.

The module is intended for use in network tester applications, as indicated in the Softing IT Networks product catalog. It serves as a component for diagnosing, measuring, and analyzing network connections. Use in measurement technology requires high signal stability and reliability, which are ensured by the module’s specific technical parameters.

Compatibility and accessories include use with compatible fiber cables, particularly multimode cables with LC connectors. A suitable accessory is the switch module ALL4757 SFP+(Mini-GBIC), also designed for 10 Gbit/s, SR/LC, multimode. Combining with such modules enables integration into existing network infrastructures. No additional adapters or converters are required, as the physical and logical interfaces conform to standards.

Installation is performed by simply inserting the module into an SFP+ port of a network device, such as a switch, router, or server. The plug connection is mechanically stable and ensures a secure connection. Electrical and optical coupling occurs automatically once the module is correctly inserted. No additional tools or settings are required, as the module technology is plug-and-play.

In operation, the module provides reliable and stable data transmission at high speed. The use of multimode fiber and the 850-nm wavelength ensures efficient signal transmission, optimized for indoor network applications. The maximum reach of 400 meters allows flexible network planning without additional amplifiers or regenerators. Compatibility with 10GBASE-SR/SW and 10G Fiber Channel ensures interoperability with a wide range of network devices and systems.
