The 10GBASE-T SFP+ transceiver module delivers the flexibility & port density well known to the SFP+ form-factor, utilising Cat 6a UTP structured cabling for network connectivity. It is a power-optimised solution for lengths up to 30m, engineered to deliver a minimum power saving of at least 0.5W per port compared to an equivalent embedded 10GBASE-T RJ45 for the same length (Cat 6a, up to 30m). These power savings can add-up in To R, mid-row & end-of-row switch connectivity. It’s the alternative compared with standard SFP+ SR/LR fibre optics, which uses standard-based technology with the familiar RJ45 connector & provides backward compatibility with legacy networks. ...

D-Link's 10 G SFP+ module series are hot-swappable SFP+ transceivers that plug into SFP+ slots on switches & support 10 G Ethernet. The D-Link 10 G Base SFP+ module series transceivers offer customers a wide variety of 10 G Ethernet connectivity options for data centers, enterprise wiring closets, & service provider transport applications. The transceivers use the Enhanced Small Formfactor Pluggable format (SFP+). The SFP+ form factor is smaller than other form factors such as Xenpak, X2, & 10 G XFP, ensuring lower costs, lower power disruption, & higher port density. They provide the necessary signal amplification for data to be transmitted to the network cable from the port, & vice versa, for the port to receive data from the network cable. All D-Link transceivers are hot-pluggable. You can connect a transceiver while the system is powered on without causing any problems. This permits modules to be added or removed without interrupting the network. The transceivers all support 10 G Ethernet, which results in very fast data transmissions of up to 10 Gbit/s. This is 10 times faster than Gigabit Ethernet & enables the switch to handle faster & higher data transmissions, making it very suitable for business needs. ...

All ports support auto-negotiation of MDI/MDIX cross over. This eliminates the need for cross over cables or uplink ports. Any port can simply plug to a server, a hub or a switch, using the usual straight-through twisted-pair cable. With 24 plug-&-play ports, the switch is a perfect choice for workgroups to upgrade performance in a client/server environment. The ports can be connected to servers in full-duplex, or hubs in half-duplex. With low-cost connection per-port, the switch can be set up for direct connection from the PCs. This relieves data bottleneck by giving each workstation a dedicated bandwidth on the network. The DES-1024D is an unmanaged 10/100 Mbps switch designed to enhance workgroup performance while providing a high level of flexibility. Powerful yet easy to use, this device allows users to simply plug any port to either a 10 Mbps or 100 Mbps network to multiply bandwidths, boost response time & satisfy heavy load demands.

The DES-105 5-Port Fast Ethernet Unmanaged Desktop Switch is a 5-port 10/100 Mbps Fast Ethernet switch that means that you can quickly set up a wired network. Connect the DES-105 to multiple computers together to share files & folders, or connect it to a router to share an Internet connection. Auto-Sensing 10/100 Ports The DES-105 uses auto-sensing 10/100 Mbps ports, allowing a small workgroup to flexibly connect to Ethernet & Fast Ethernet devices to create an integrated network. These ports detect the network speed & auto-negotiate between 10BASE-T & 100BASE-TX, as well as between full & half-duplex, allowing you to get the maximum speed possible for each device connected to your network. Auto MDI/MDIX Crossover All of the ports on the DES-105 support automatic MDI/MDIX crossover, eliminating the need for crossover cables or uplink ports. Each port can be plugged directly to a server, hub, router, or switch using regular straight-through twisted-pair Ethernet cables. In addition, the DES-105 features multiple front, easy-to-access Ethernet ports with two colour LED indicators per port to easily distinguish link status. Flow Control for Secure Transmission When a port reaches its receiving buffer capacity, the 802.3x flow control feature activates to minimize dropped packets. By minimizing the number of dropped packets, the switch provides a more reliable connection for all of your connected devices while surfing the web, playing games, or accessing media. Think Green The DES-105 is a plug-&-play networking switch that offers D-Link’s Green Technology to save energy & reduce heat, which in turn extends product life without sacrificing performance or functionality. The switch supports IEEE 802.3az Energy-Efficient Ethernet (EEE) which detects when a connected computer is shut down or when there is no Ethernet traffic, in which the switch will proceed to power down the idle port, saving a substantial amount of power. ...
