The inner diameter of the first through-hole is substantially equal to the diameter of the optical fiber, and the optical fiber is fixed within the first through-hole. The first supporting part includes an accommodating portion for accommodating the first positioning part. The first positioning part is fixed in the accommodating portion. | 2015-12-17 |
20150365172 | Upstream Optical Transmission Assignment Based on Transmission Power - An apparatus comprises a receiver configured to receive first messages, a processor coupled to the receiver and configured to process the first messages, determine transmission powers associated with the first messages, and generate a transmission scheme based on the transmission powers, and a transmitter coupled to the processor and configured to transmit a second message comprising the transmission scheme. An apparatus comprises a transmitter configured to transmit a first message indicating a transmission power of the apparatus, a receiver configured to receive a second message, wherein the second message assigns to the apparatus a wavelength based on the transmission power, and a processor coupled to the transmitter and the receiver and configured to process the second message, and instruct the transmitter to transmit a third message at the wavelength. | 2015-12-17 |
