Juniper Networks has expanded the range of interface cards for its MX-series portfolio of Ethernet Services Routers 
with the addition of three new interchangeable dense port concentrator (DPC) families.
The new dense port concentrator (DPC) cards, which are interchangeable across the entire MX-series family — including the MX240, MX480 and MX960 — include:
- New copper-based Tri-rate (10/100/1000) Ethernet DPCs which enable customers to support low-speed interfaces as well as the existing high-speed interface options.
- New 20 Gbps DPCs, which are more cost effective and efficient, requiring less power than full 40 Gbps cards. The 20 Gbps DPCs enable cost- or energy-conscious customers to benefit from the long-term investment protection that comes from the MX-series’ superior performance and scalability, while keeping capital and operational costs at a minimum.
- New Multi-rate DPCs, which increase flexibility and efficiency by enabling customers to support both Gigabit and 10 Gigabit Ethernet interfaces on a single line card.
The Tri-rate Ethernet and 20 Gbps DPCs are available immediately; the Multi-rate DPCs are expected to become available in the second half of 2008.http://www.juniper.net.
