The Dual-Port Gigabit Ethernet Trunk module provides a flexible network interface module for all MD8000 series applications. This single card provides interfaces to two separate transport networks, each of which can operate at any of the popular Ethernet interface speeds of 100 Mbit/sec or at 1000 Mbit/sec. This flexibility gives network designers the ability to create a wide range of redundant or non-redundant network architectures that comply with all applicable Ethernet signal standards.
Both electrical and optical interfaces are supported. The MD8000-2GbE-E (electrical) version includes two standard RJ-45 electrical connections that can be used for full-duplex 100 or 1000BaseT applications. The MD8000-2GbE-O (optical) units are designed to provide two independent optical Gigabit Ethernet connections. These units require one Small Form-factor Pluggable (SFP) device for each of the two interfaces, which can be independently selected for the desired optical wavelength and distance from one of four choices.
The MD8000-2GbE module can be installed in any available slot in the 4-RU MD8000 chassis, the 7-RU MD8000EX chassis, or the 2-RU MD8000SX chassis. In combination with MD8000 signal interface cards and the flexible switch/controller units, many different types of media signals can be transported over common Ethernet network infrastructures. Full system configuration and alarm reporting is available through the extensive SNMP MIB and the ProMD Network Management System (NMS).
