Problems solved by technology

[0004] The connectors currently used in the field of optical communications are mainly composed of the following parts, such as Figure 1 Shown: Outer frame sleeve, stop ring, spring, ferrule with tail handle, and tail sheath are five parts in total. This connector can realize bidirectional transmission of light, that is, light energy can be smoothly transmitted from one optical fiber to Another optical fiber, but similarly, the return light reflected by the end face can also return to the original path, causing interference to the system

Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as Figure 2 to Figure 3 A kind of ultra-miniature optical fiber connector with isolator shown, comprises stop ring 2, spring 3, ferrule 6 and tail sheath with tail handle 5, also includes an ultra-miniature in-line isolator 4, described The tail sheath includes a left tail sheath 1 and a right tail sheath 7, wherein the left tail sheath 1 is sleeved on the left end of the stop ring, the tail handle is connected with the right end of the stop ring 2 through a spring 3, and is inserted Core 6 is connected with right tail sheath 7. The ultra-miniature in-line optical isolator 4 is installed at the end where the ferrule 6 with the tail handle 5 is connected to the stop ring.

[0023] Without changing the original on-line optical isolator production process, the high-density oxide ceramic sleeve is used to replace the glass tube...

Abstract

The invention discloses a subminiature optical fiber connector with an isolator. The connector comprises a stop ring, a spring, an inserted core and a tail jacket, wherein the inserted core is provided with a tail handle. The connector is characterized by also comprising a subminiature online isolator; the tail jacket comprises a left tail jacket and a right tail jacket; the left tail jacket is sleeved at the left end of the stop ring; and the tail handle is connected with the right end of the stop ring through the spring and is connected with the right tail jacket through the inserted core. Adverse influence of reflected light on the stability of spectrum output power of a light source is reduced to a great extent, the working stability of an optical fiber amplifier is enhanced and power loss caused by stimulated Brillouin scattering is reduced.

Description

technical field [0001] The invention relates to an ultra-small optical fiber connector; that is, to ensure the smooth transmission of light from one optical fiber to another optical fiber to realize the transmission of light (optical signal), in particular to an ultra-small optical fiber connector with an isolator. Background technique [0002] The online optical isolator is widely used in optical fiber communication, and its function is to prevent the adverse effects of the backward transmitted light (ie reflected light) in the optical path on the light source and the optical path system due to various reasons. For example, installing an optical isolator between the semiconductor laser source and the optical transmission system can greatly reduce the adverse effects of reflected light on the stability of the spectral output power of the light source. In high-speed direct modulation and direct detection optical fiber communication systems, the backward transmission of light ...
