Problems solved by technology

Optical communication technology is inseparable from fiber coupling components used for fiber coupler connection. Pigtail is the most common fiber coupling component in optical communication. The existing pigtail has SC standard plug at one end and steel ladle with LC ferrule at the other end. Needle, the end grinding angle of the LC ferrule is 6° or 8°, no matter which of the above-mentioned ferrule specifications, it can only be applied to one optical network, and the loss is large during use, which is harmful to the active parts of the transmitter. greater impact

Abstract

The invention discloses a non-standard fiber coupling assembly for a PON network and a making process thereof; the non-standard fiber coupling assembly comprises a fiber, and a SC standard plug and a SC type ladle needle respectively connected on two ends of the fiber; the SC type ladle needle is formed by pressing a metal caudal peduncle with a SC type ceramic ferrule; the SC type ceramic ferrule grinding angle is 7.5+ / -0.03 degrees. The ladle needle employs the SC type ceramic ferrule with the grinding angle of 7.5+ / -0.03 degrees, and the assembly can be applied to the EPON and GPON optical networks and is high in compatibility, thus greatly improving return loss, and reducing emission end influences on the active parts; in addition, the SC type ceramic ferrule is lower in cost when compared with a LC type ceramic ferrule, simple in grinding process, and high in yield; the non-standard fiber coupling assembly is suitable for connecting fiber couplers.

Description

technical field [0001] The invention belongs to the technical field of optical communication and is used for the connection of optical fiber couplers, in particular to a non-standard optical fiber coupling assembly used in PON networks and its manufacturing process. Background technique [0002] In recent years, optical communication technology, as a communication technology different from traditional analog signals, has developed rapidly due to its characteristics of high speed and large capacity, and has become the main transmission means of modern communication networks. [0003] At present, in optical communication, the commonly used light source is in the form of TO-CAN. The chip is packaged in a tube, converged into a focal point through a lens, and then coupled into an optical fiber. Corning's SMF-28e+ is widely used in optical communication. single-mode fiber. Optical communication technology is inseparable from fiber coupling components used for fiber coupler conne...
