Single Fiber Solutions for 400G Wavelengths
What is this white paper about?
Fiber optic networking used to require two fibers, one for transmitting and one for receiving signals simultaneously. Single fiber solutions emerged as a way to reduce costs of dark fiber solutions and optimize fiber. Rather than using two dedicated strands, a single fiber strand that carries a bi-directional signal is used.
For enterprises leasing dark fiber from providers, the operational savings are significant.
The challenge is to maximize revenues while reducing their largest expenditure - monthly cost of the fiber link. Using single fiber reduces operational costs by 50%, making dark fiber an affordable solution.
In DWDM, active and passive solutions for single fiber transmission range from 4 up to 8 400G wavelengths, with optional optical amplifiers. The single fiber solution seamlessly integrates with any standards-based 10/25/100Gb Ethernet, 16/32G Fibre Channel, and OTU2/2e/4 client interfaces, and supports any mix of up to 400G services.
