Dowslake Microsystems , a provider of smart network building blocks from Ethernet to wavelength division multiplexing (WDM) , has introduced the MTS1080 1U, 19-in. rack mount 10 Gigabit Ethernet transport switch, featuring up to 12 Gigabit Ethernet ports for user services and two 10 Gigabit Ethernet ports for either point-to-point or ring network configurations. All user or link ports use pluggable optics, making it simple to increase bandwidth for more service revenue. It features all standard Ethernet functions, such as circuit configuration via VLAN or double VLAN, and a built-in pluggable WDM module, allowing operators to add bandwidth by simply cascading more MTS1080 without the need to lay new fiber. As a result, the MTS1080 provides not only TDM multiplexing and ADD/DROP functions as a traditional Ethernet switch, but also allows aggregation in the wavelength domain, making it possible to do both TDM and WDM multiplexing and ADD/DROP within the same 1U 19-in. “pizza-box."The MTS1080 supports Ethernet automatic protection switching (EAPS, according to RFC3619), so that in the event of a fiber or equipment failure the Ethernet ring can be healed within 50 ms, meeting SONET/SDH standards. Extended management features include in-band remote management, SNMP tools, CLI and GUI.
