How Cisco IT Used CWDM to Interconnect Japanese Data Center Sites

Although a dedicated data center appeared to be a good solution, the cost of providing reliable connectivity between the data center and the two sales offices seemed prohibitive. To provide an acceptable level of reliability and redundancy, a circuit would be needed from the data center to Akasaka, from Akasaka...

WDM/CWDM/DWDM: Segmentation Primer-Maximizing Capacity for Revenue

Node segmentation provides a good tool for cable operators to increase targeted ser1ces, such as EOD, Internet data, and telephony. In many cases, cable operators have limited fibers and/or they could reclaim fibers for emerging opportunities such as commercial services. WDMICWDMIDWDM techniques offer better utilization of the existing fiber resources....

10 Gigabit Ethernet Over Legacy Multimode Fibre

The distance capability of existing 10 Gigabit Ethernet products is severely limited by modal bandwidth. 10GBASE-SR supports only 33m with OM1 and 82m with OM2. A 4-channel CWDM version, 10GBASE-LX4, increases the operating range to 300m using existing multimode fibre types however this solution is complex and products are not...
