摘要： A telecommunication appliance and method is described. In the method, a flexible cover part of an appliance cover of a telecommunication appliance supported by a telecommunication rack is removed while the telecommunication appliance is in service and passing data. The telecommunication appliance has a plurality of pluggable optical modules installed within connectors within a space encompassed by the appliance cover. The connectors are operably connected to a power supply supplying power to the connectors. When a first one of the connectors is devoid of a pluggable optical module being installed within the first one of the connectors, a first pluggable optical module is plugged into the first one of the connectors.

摘要： Systems, methods, and devices for adding an alien or native wavelength optical signal to a fiber optic line. A portion of a spectrum of the fiber optic line corresponding to the optical signal is blocked with a wavelength selective switch (WSS). The portion of the spectrum is gradually unblocked until a power of the optical signal measured after the WSS is equal to a predetermined level. If the power and characteristics of the optical signal after the WSS satisfy one or more criteria, the portion of the spectrum is further unblocked until the power of the optical signal measured at the output is equal to an operational level.
