OCTOBER 20, 2009 -- Optelian has announced the availability of the MPX-81-EX Gigabit Ethernet (GbE) muxponder for aggregation and switching applications.

“Because of its flexibility, this is a very useful card for a wide variety of Ethernet applications over optical transport networks,” said Dave Mills, vice president, sales, for Optelian. “Not only does it optimize bandwidth, but it also provides carrier-grade support of Ethernet LAN, WAN, E-LAN, and E-Line type services.”

The MPX-81-EX has eight GbE client ports, and two 10GbE line LAN/WAN ports. Client ports use SFP transceivers, and line ports use XFP transceivers, allowing the unit to interface with a wide variety of equipment and network configurations including CWDM or DWDM systems for even higher fiber utilization. This unit joins the MPX-3GOTN (four 2.5-Gbps signals into one 10-Gbps OTU-2 signal) in the LightGAIN muxponder product line.

The MPX-81-EX can serve as a simple eight GbE to one 10GbE muxponder to free fiber or wavelengths for other services. It can also serve as an Ethernet switch with Provider Bridge VLAN capability. The two 10GbE interfaces can be set independently to LAN or WAN interfaces to enable the device to act as a LAN-to-WAN PHY converter for transporting 10GbE LAN signals over SONET networks. Standard Ethernet features such as Rapid Spanning Tree, support for jumbo packets, and performance monitoring statistics are included.

With the addition of the MPX-81-EX, Optelian asserts its LightGAIN system now provides a fully integrated Layer 1 and 2 system in a reliable, small footprint, low-power consumption package. It will be particularly useful for conserving fiber on mobile backhaul and IPTV/triple-play applications, as well as allowing service providers to offer additional Ethernet services over their networks, the company concludes.
