There is a need for increased network bandwidth to meet the global IP traffic demand, which is growing at a rate of 30% per year. In order to meet this demand, an effective migration strategy is required to transition from 10 Gigabit Ethernet (10GbE) to 40 Gigabit Ethernet (40GbE) and 100 Gigabit Ethernet (100GbE) over multimode fiber for switch-to-server and storage area network connections in data centers and for core switching and routing connections in the backbone.
This presentation will provide an overview of the cabling requirements that are contained in the IEEE 802.3ba standard for 40GBASE-SR4 and 100GBASE-SR10 Ethernet.
Because optical loss testing is not as simple as it seems, this presentation will also provide guidance on a test methodology to ensure accurate optical fiber loss measurements in the field. The need for low-loss connectors to meet tight insertion loss budgets for 40G and 100G Ethernet links will also be discussed.
The use of pre-terminated optical fiber cabling can facilitate a seamless migration path to 40 GbE and 100 GbE using the same cabling infrastructure, simply by adding trunk cable assemblies and changing out connectivity modules as needed.
In a replacement scenario, the breakout cassettes that provide duplex LC, 10 GbE connections, are replaced with MPO adapter frames and modules that provide 40 GbE and 100 GbE connections in the same physical space and using the same patch panels.
In an augmentation scenario, standard-density duplex LC cassettes are replaced with high-density duplex LC cassettes leaving room for additional 40 GbE and 100 GbE connections using MPO adapters.
