The invention relates to a method for transmitting a plurality of antenna signals in a wireless Base Transceiver Station (BTS) using Remote Radio Head (RRH) technology and the corresponding system. The method includes the steps of: transmitting signals over the transmit channel using Synchronous Digital Hierarchy (SDH) / Optical Transmission Network (OTN), multiplexing the plurality of antenna signals adopting the manners of time division multiplex or GFP frame-level multiplex; forming the multiplexed antenna signal stream and in-band control signaling stream into Generic Framing Procedure (GFP) frame; or forming the plurality of antenna signals and the plurality of respective control signals on the in-band control signaling channel into a plurality of respective GFP frames in parallel; and further mapping the GFP frames to STM-N / OTM-n frames, therefore multiplexing the plurality of antenna signals and the in-band control signaling stream to realize the SDH / OTN-based transmission. According to the invention, in the circumstance of using a plurality of antennas for transmitting signals, the strict time and phase relations between various antenna signals can be ensured, and also system complexity can be simplified, the transmission delays from various antenna signals to CBTS are totally the same.

An optical waveguide fiber comprises: (a) a core with a refractive index profile having, a radius, an alpha and a relative refractive index characterized by delta % that varies along the radius; (b) at least one cladding surrounding the core; wherein the alpha is less than 2.5, peak refractive index delta % is between 0.34% and 0.4%, the relative refractive index is less than 0.01% for all radii greater than 7 μm, and this optical waveguide fiber has a mode field diameter MFD at a wavelength of 1310 nm of no more than 9.54 μm, and attenuation less than: (a) 0.329 dB / km at a wavelength of 1310 nm, (b) 0.290 dB / km at a wavelength of 1383 nm, (c) 0.255 dB / km at a wavelength of 1410 nm, and (d) 0.189 dB / km at a wavelength of 1550 nm.

The invention relates to the technical field of medical monitoring, in particular to a medical monitoring method and device integrating a central monitoring function, and provides a method for realizing a central monitoring server by a single patient monitor device. The single patient monitor device is capable of monitoring physiological parameters of a patient and simultaneously realizing data collection and processing functions of other monitor devices through a wired or wireless local area network, and the operation states and patient information of other monitors can be examined on the current monitor. The monitor can display the current monitoring and measuring information and the patient information of all the other monitors networked with the current monitor at the same time, and other networking monitors can be controlled through the current monitor. The monitor is used for displaying in a single screen or multi-screen manner, and display contents can be the same or different. Therefore, a single patient monitor realizes internetworking functions, is convenient for information browsing and viewing, improves the information processing efficiency and lowers the internetworking cost of the central monitoring server.
