摘要： A signal received in a wavelength division multiplexing system is delayed and an exclusive OR logical operation is performed on the received signal and the delayed received signal. Then, the direct current voltage of a selection signal which is a result of the operation is measured to identify the bit-rate of the received signal. When a mixture of various signals having different bit-rates are used over a network in the wavelength division multiplexing system, a receiving terminal can automatically recognize information on the bit-rate of a received optical signal and extract a reference clock signal from the received signal, thereby reproducing the received optical signal without distortion, using the clock signal.

摘要： A latch type optical communication module is easily mounted to and detached from a system port having a cage by means of a latch. The optical communication module is provided with a latch. The latch is rotated around a hinge shaft fixed to both sides of a receptacle and engaging latch holes of ends of the latch. When rotated the latch moves latch drivers to force a slider upward, the slider raises a groove engaging a fixing tap of the optical communication module thereby allowing the optical communication module to be detached from the system port. The optical communication module can be detached from the system port without a tool or influence or adjacent an optical communication module.

摘要： An optical communication module is provided with a platform to provide an accurate axial alignment with optical transceiving subassemblies. In the optical communication module, axes of the optical transceiving sub-assemblies are aligned by virtue of previously established axial alignment of the platform, and the platform is fixed to a main body by inserting an insertion jaw of a cover into an insertion groove formed on an upper surface of the platform. After the optical transceiving subassemblies are inserted into the platform having the axial alignment required for a system, a bonding agent is filled into spaces defined in the platform, thereby preventing the axes from deviated by an external force. The optical communication module allows for easier and more accurate guidance of a connection between the optical transceiving sub-assemblies and the optical connector, thereby minimizing the optical loss, and preventing the patterns on the printed circuit board from being damaged due to the insertion and disconnection of the optical connector.
