Carrier-Class Ethernet with Optical Wireless Mesh
In this section, we discuss how optical wireless mesh networking technology fares in
terms of some of the key attributes required to deliver carrier-class Ethernet services.
Failure Resiliency FSO technology is a simple physical layer transport technology that
can surpass all other wireless technologies in its ability to offer high-quality data transport
service. When deployed at short distances, it can offer immunity from all weather
conditions. It uses the same underlying technology as fiber-optic communications, and
it can provide link-level performance comparable to that of fiber optics. Due to its immunity
from external RF interference, FSO can offer fiber-like performance with much
more consistency than other wireless technologies that are susceptible to interference.
Therefore, FSO technology, when deployed properly, can provide the kind of failure
resiliency required to offer Carrier Ethernet services.
No physical layer technology is 100 percent immune from failure due to external
events and FSO is no exception. The time-proven method of achieving resiliency in a
network using any physical layer technology is by means of redundancy, and redundancy
is one of the key attributes of a mesh network.
