Abstract
The utility model discloses an APC (Automatic Power Control) butting single-fiber two-way device which comprises a receiver, a laser, a filter and an interface, wherein the laser is welded on a metal pipe seat; the filter is fixed on a metal shell; the metal shell is welded on the laser; a chip of the laser aligns to the interface; the metal shell is welded to the interface; the receiver and the metal shell are assembled together; and a end surface where the interface is butted with an optical fiber moving connector is an APC slope of 8 degrees. Because the end surface where the interface is butted with an optical fiber moving connector is the APC slope of 8 degrees, the APC butting single-fiber two-way device can be favorably butted with an APC optical fiber moving device, thereby improving the reflecting index of a product and reducing Fresnel reflection loss caused by a clearance between connectors.
Description
Technical field
The utility model relates to a kind of Angle PC (Angled Physical Contact) single fiber bi-directional device.
Background technology
The single fiber bi-directional device is that semiconductor laser is merged by packaging technology with semiconductor light receiver, manufactures to have optical communication standard interface product.The single fiber bi-directional device mainly is used in the optical communication equipment, and optical transmitting set is used for to be light signal, to be connected with transmission medium (optical fiber) by standard interface, finish the function of transmission information electrical signal conversion in the device; Optical receiver is connected with optical fiber by standard interface in the device, is electric signal with the converting optical signals that transmits in the optical fiber, finishes the function of reception information.
Device receives and emission interface is a standard interface, the single fiber bi-directional device application is in module, device interface docks use with the external fiber mobilizer, be applied to the product of analog signal transmission such as GPON optical communication networking system or CATV, in order to improve product reflection index, reduce the Fresnel reflection loss that the gap causes between the connector, the optical communication merchant requires to adopt the APC type optical fiber mobilizer butt joint of high reflection, and the interface of existing product all is to adopt the PC spherical structure, must adopt PC type fiber active linker, so can't achieve a butt joint.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of Angle PC (Angled Physical Contact) single fiber bi-directional device is provided, and the end face that its interface docks with fiber active linker is the APC inclined-plane.
The technical solution of the utility model is: a kind of Angle PC (Angled Physical Contact) single fiber bi-directional device, comprise receiver, laser instrument, filter plate and interface, described laser instrument and the welding of metal base, described filter plate is fixed on the metal shell, described metal shell and laser instrument welding, the chip of described laser instrument is aimed at interface, described metal shell and joint weld, described receiver and metal shell are assembled together, and the end face that described interface docks with fiber active linker is APC8 ° of inclined-plane.
Compared with prior art, the utility model has the advantages that: because the end face that interface docks with fiber active linker is APC8 ° of inclined-plane, therefore can realize well and the docking of APC type optical fiber mobilizer, improve the reflection index of product, reduced the Fresnel reflection loss that the gap causes between the connector.
