Abstract
The present invention provides methods for aligning a fiber optic cable with an optical component on a device carrier using a fiber optic lens assembly. One method provides that movement of the lens assembly is fixed with respect to the fiber optic cable. Light is sent through the lens assembly. The fixed lens assembly and fiber optic cable are moved with respect to the device carrier. The light sent though the fixed lens assembly is monitored, and movement of the fixed lens assembly is fixed with respect to the device carrier according to the monitored light. Another method provides that movement of the lens assembly is fixed with respect to the device carrier. Light is sent through the lens assembly. The fixed lens assembly and device carrier are moved with respect to the fiber optic cable. The light sent though the fixed lens assembly is monitored, and movement of the fixed lens assembly is fixed with respect to the fiber optic cable according to the monitored light. The present invention further provides aligned transceiver assemblies having a fiber optic cable, device carrier, and fiber optic lens assembly having features that facilitate alignment and fixing according to the invention methods.
