Embodiment Construction

[0019] As we all know, for optical fiber, there are usually no physical barriers to simultaneous transmission and reception on optical fiber. In addition, it is well known that there is usually an asymmetric bandwidth requirement in the two directions. However, there are many challenges, one of which is to properly filter the signal to avoid transmission in the opposite direction that causes reflections that cause mutual interference. Such filtering increases implementation cost. Furthermore, in conventional implementations of variable transmission and reception (eg, 10% of the wavelengths are allocated for traffic in one direction and 90% for traffic in the other direction), variable filters are required. Methods and corresponding apparatus are disclosed below for distributing, and if necessary redistributing, individual links in multiple to single direction data traffic.

Abstract

In a configuration wherein N individual fibers interconnect two devices, each fiber can be configured, through configuration of the packet processing devices at each end of the fiber, to carry traffic in a single direction. From the perspective of the first device, an arbitrary subset T of the N fibers can be used for transmitting signals to the second device. The packet processing devices terminating a subset R of the remaining N-T fibers can be configured so that the first device may receive signals from the second device.

Description

[0001] Related Applications Cross Application [0002] This application claims priority to prior application to U.S. Patent Application No. 15 / 056,335, filed February 29, 2016, entitled "Fiber-Non-Symmetric Interconnection over Fiber," which earlier The content of the application is incorporated herein by reference. technical field [0003] The present application relates generally to optical networks and, more particularly, to optical fiber asymmetric interconnections. Background technique [0004] Link aggregation (Link Aggregation, LAG) allows multiple parallel network links between a first device and a second device to be regarded as a single network link. An aggregated link becomes a logical link with a higher capacity than any individual network link. Individual network links in an aggregated link may be referred to as "LAG members." A bidirectional LAG is usually implemented as a pair of optical fibers: one optical fiber for transmission (transmit, TX), and one opt...
