摘要： A uniform and unified firmware in-field upgrade capability for the optics modules may ensure compatibility, security and code quality, and scalability. In some examples, an intermediate representation, which includes vendor firmware upgrade operations and control logic, may be defined, received, and parsed. Read/write operations may be communicated to optical module(s) based on the control logic. In some examples, a unified optics module firmware in-field upgrade framework, which has multiple defined software layers, may ensure a uniform and unified approach to managing optics module(s) from different vendors and used by different projects. The software layers that may properly translate optics module read/write operations, abstract and make uniform the read/write operations, provide libraries of intermediate representations, package the intermediate representations into executables/scripts, monitor optics module status, determine when a new firmware is released, and gradually upgrade the optics module firmware.

摘要： An optical links diagnostic system (LDS) and its operation within an optical circuit switch (OCS) for measurement and diagnosis of fiber-optic network fiber performance and quality is disclosed. The LDS can contain two photodetectors, a laser source, and be coupled to an OCS. Optical circulators can further be linked to the OCS. The LDS can be used both as an optical time domain reflectometer (OTDR) or as an optical return loss (ORL) meter and can automate the diagnosis of the fiber optical network fiber insertion loss and return loss.
