摘要： A digital burst mode communication system operates at a fixed wavelength for transmission and reception of burst mode signals using a pair of transceivers and a single optical cable. The stray noise level in the system is significantly reduced by use of angled plate absorbers that receive scattered transmission burst signal from a 45 degree partially reflecting mirror. Isolation of received burst signal from transmitted burst signal is increased to better than 30 dB. The system operates by sending only data bits across the single optical cable without scrambling or encoding preambles, significantly improving the efficiency of high speed communication.

摘要： Radially symmetric splicer joint and locking assemblies and connectors for optical fibers are provided. The assemblies use splicer joints formed from a slightly deformable plastic material. The splicer joints contain an axial bore having a diameter slightly less then the diameter of the stripped ends the optical fibers inserted into the axial bore. When a stripped fiber is inserted into the axial bore of the splicer joint, the bore expands slightly to frictionally receive the stripped end. The assemblies and connectors use radially symmetric locking to secure the fibers therein. The radially symmetric locking and the surface tension provided by the axial bore against the stripped ends of the fibers minimizes the occurrence of mis-alignment and reduces insertion and return losses.
