摘要： An optical add/drop system supporting a colorless, directionless, and contentionless (CDC) architecture includes a Contentionless Wavelength Selective Switch (CWSS)-based optical add/drop device including N local add/drop ports and M degree ports; and a channel pre-combiner including a common port connected to a first port of the N local add/drop ports and at least two local add/drop ports coupled to the common port. The CWSS-based optical add/drop device can include an M-array of 1×N Wavelength Selective Switches (WSSs) and an N-array of M×1 switches. The channel pre-combiner can be a passive device which passively combines the at least two local add ports and splits the at least two local drop ports. The channel pre-combiner can also include amplifiers on the common port in both an add direction and a drop direction.

IPC分类号： H04B10/079
摘要： The embedded apparatus disclosed herein may measure reflection coefficient values associated with back reflections in a fiber optics transmission system during a variable detection window to detect normal conditions, simulated Brillouin scattering (SBS), or excessive back reflections triggering remedial action. For example, the back reflections may indicate normal conditions if the reflection coefficients measured during an entire detection window remained below a threshold or a maximum reflection coefficient observed therein was below the threshold. Alternatively, the back reflections may trigger remedial action if the reflection coefficients measured in the entire detection window exceeded the threshold or a minimum reflection coefficient observed therein was above the threshold. Otherwise, the back reflections may indicate the SBS effect if the reflection coefficients measured during the detection window included points above and below the threshold or the minimum and maximum reflection coefficients observed therein were below and above the threshold.

摘要： A method of analysing performance of an optical fiber link. As a preliminary step, a reference trace indicative of a distributed optical performance of the optical fiber link is derived. During in-service operation of the optical fiber link, an Optical Time Domain Reflectometry (OTDR) sub-system measures an OTDR trace with Raman amplification ON, and a real-time cumulative Raman Gain profile of the optical fiber link is calculated based on the reference trace and the measured OTDR trace.

摘要： An optical node supporting a modular deployment and upgrade of optical spectrum includes one or more C+L-Band amplifier modules; and a modular base module configured to interface one or more C-Band optical modems; wherein, in an initial deployment configuration, the modular base module provides channelized Amplified Spontaneous Emission (ASE) loading for select channels in the C-Band via a first ASE noise source coupled to a multiplexer for the C-Band, bulk ASE loading over the L-Band via a second ASE noise source coupled to an L-Band output, and an upgrade port for connection to an L-Band upgrade module. The L-Band upgrade module can selectively connect to the upgrade port to provide an L-Band upgrade configuration where the L-Band upgrade module and the modular base module coordinate transition of the bulk ASE loading to L-Band channelized ASE loading via a third ASE noise source.
