400 Gigabit Ethernet Fiber Optical Cabling
The Future of High-Performance-Backbones
The future development of data center cabling is clearly moving towards 400 Gbit/s. The 400GBASE-SR16 transmission protocol standardized according to IEEE 802.3bs emphasizes the MPO Interface with 32 fibers. Both connector faces are not compatible with the MPO-12.
However, 400 Gbit/s can be realized without problems with Base-8 cabling. If URM trunk cabling is already there, only the patch cable needs to be replaced with a special fanout cable. This converts the MPO connector’s 32 or 16 fibers to a total number of 4 or 2 URM NG P8 connectors, depending on the transmission protocol.
Cabling over MPO is also possible although there is no compatibility with MPO-12 or MPO-24 at the active port.
With speeds of 40 to 400 Gbit/s, even short-distance data transmission is possible (up to 500m) using the PSM4 and DR4 standards. In this case, four singlemode fibers are used as transmission medium with LC(dx) or MPO-12 serving as interface. Cabling with singlemode fibers offers the undeniable advantage of a great loss budget (3dB).
