Allied Telesis UMC2000/SP-901 Transceiver/Media Converter
Overview
The current standard USB connector is USB Type-A. Even as the world has moved from USB 1 to USB 2 and on to modern USB 3 devices, that connector has stayed the same. Since it only plugs in one way, it has always been necessary to make sure it is correctly oriented before plugging in.
However, with USB-C, both ends of the cable are the same, allowing for reversible plug orientation. It can also be plugged in upside down as it will function both ways.
The time of differently-shaped connectors for differently-sized devices is coming to a close. USB Type-C is a new connector standard, and it is very small-about one third the size of the old USB Type-A plug.
The UMC Series comes with two types of USB cables, allowing for use with older USB-A and the new USB-C products.
Extended network
UMC Series converters are ideal for extending a fast Ethernet or Gigabit network. The series is designed to be a mobile system to extend the distance of a network by utilizing a USB-A or USB-C port with connectivity to fiberoptic cabling. The UMC Series features a USB port (Type A or C) and either a fixed fiber port (SC, ST or LC) or an SFP port which is capable of accepting a 100MB or 1000MB SFP.
VLAN support
Many new backbone switch products now support the industry-standard IEEE 802.1Q specification for Virtual LANs (VLANs), which send extra-long data packets on the network.
Some media converters don't support this feature and discard extralong packets-but UMC200/2000 converters are fully compatible with these long packets, making them the perfect solution for today's modern networks.
Small and flexible
The small size and external power of the UMC Series allows them to be used almost anywhere.
- IEEE 802.1Q VLAN tagging and 2 VLAN ID filtering; received VLAN Tag (4 bytes) can be stripped off or preserved
- TCP Large Send Offload V1
- IEEE 802.1P Layer 2 priority encoding and decoding
- IPv4/IPv6 packet Checksum Offload Engine (COE) to reduce CPU loading, including IPv4 IP/TCP/UDP/ICMP/ IGMP & IPv6 TCP/UDP/ICMPv6 checksum check and generation
- Advanced link-down power saving if Ethernet cable is unplugged
- Auto-detach power saving. Softdisconnected from USB host when Ethernet cable is unplugged
- Dynamic power management to reduce power dissipation during idle or light traffic
- Power management offload (ARP and NS)
- Supports both USB-C and USB-A ports
- Suspend mode and remote wakeup via link-change, Magic Packet and Microsoft wakeup frame
