The model 4K16 Switches boost the performance of medium-sized Ethernet LANs, with the flexibility of both twisted-pair and fibre swirtched ports. Fibre ports may number zero, one or two, and a variety of user selected fibre connector types may be configured. The 4K-Series provides the switching speed and the reliability to smoothly support multiple workgroups, each with its own switched 100Mb or 10Mb domain, for increased network performance. The model 4K16 Switches are non-blocking on all 16 ports, and include large 2Mb packet buffers for advanced performance, even with unbalanced loads. The dynamic 2K-node address table allows the 16-port 4K16 to support medium sized networks. The entire 4K-Series, with store-and-forward switching, filters all faulty packets to minimize traffic congestion. Model 4K16 Switches are provided in a rack-mountable package and have a rugged metal case and an auto-ranging power supply for operation with standard AC power worldwide. "Carrier Class" and "Industrial Strength" models with an optional -48VDC input power features are also available. Please visit our website for full product information.
