S P E C I A L F E AT U R E switches & routers Single minded The Phoenix Contact range of SFP modules for managed switches has now been extended to include Wavelength Division Multiplex (WDM) variants for 100Mb/s and 1000Mb/s. With the new modules, data transmission only takes place via a single optical fibre. WDM technology enables data to be transmitted and received simultaneously, ie., bi-directionally, on a singlemode fibre. This does not limit the transmission quality or bandwidth. The technology is often used for rotating applications such as rotary tables or wind turbine generators. This means that switches and other network components can be economically and reliably connected with just one fibre via optical rotary transformers.

Part of D-Link’s DGS-1100 MP/MPP series of Gigabit smart managed surveillance switches, the range benefits from the unique inclusion of ONVIF support, this enables the DGS-110-26MP to automatically recognise both D-Link and third party IP cameras, network video recorders (NVRs) and other IP devices such as access control systems. Automatic device recognition via ONVIF means installation teams just need to plug network cables into CCTV cameras and other components, connect the cables to the smart switch and the system’s elements will appear in the switch’s dedicated surveillance optimised web interface. With a power budget of 370W, the switch is able to power multiple devices over the network simultaneously. Also on offer is the option to enter a conventional networking control panel, giving the fine-grained control of all networking options that IT teams expect. Featuring 6KV surge protection and supporting high powered PoE standards the DGS-1100-26MP ensures maximum flexibility and the opportunity to simplify networks.

The new US4 connector is the first device in which switch functionality resides directly in the connector, making it possible to network four EtherNet/IP or Profinet nodes with transmission speeds of up to 1,000Mb/s. With this enhancement, Harting’s Han-Modular connector family lends support to the trend toward integrated networking, enabling EtherNet/ IP and Profinet based communication to be extended over the plant management level control through to the enterprise level. The US4 connector module features integrated LEDs to provide quick and easy power and network diagnostics for individual ports, displaying both the presence of the Ethernet connection as well as ongoing data exchange and the associated speed information. The module automatically detects the send/receive lines of connected devices and finds the correct settings for the lines. In addition, in conjunction with the 10Base-T and 100BaseTx interfaces, it autonomously corrects polarity errors in wire pairs and reverses the polarity of the data signal. It also allows two connected Ethernet nodes to autonomously negotiate and configure the maximum data transfer rate – up to 1,000Mb/s incrementally – as well as the type of transmission, ie. half-duplex or full duplex. The US4 switch seamlessly integrates into existing Han-Modular systems, with the interfaces required to extend an Ethernet network fitting into existing modular Han connectors.

Whether the network is needed for wireless access points, IP cameras, HVAC, traditional data or access control, the ECS2100-28P has the port speed and PoE budget to cope. The ECS2100 Series supports 8, 24, and 48 10/100/1000Base-T ports, with each switch supporting 2 or 4 Gigabit SFP ports. As well as IPv4 and IPv6 features, the ECS2100 supports L3 static routing. The ECS2100 includes the best green-saving technologies (IEEE 802.3az and GreenEthernet). Using the Energy Efficient Ethernet standard, the switch automatically decreases power usage when network traffic is low. All Edgecore products are supported under a Limited Lifetime Advance Replacement Product Warranty. Products will be supported up to two years from being made End of Life. Software warranty is 90 days. Mayflex distributes the Edgecore range in the UK. For further information visit: 30 28-30 S&R Products.indd 30 03/10/2016 11:55
