Abstract

The utility model discloses a double 2*2 mechanical light switch with multiple modules, which aims to provide a light switch with small volume, reliable performance and low cost. The utility model comprises a casing, a collector, two optical fiber collimators and a movable arm with a reflective mirror, wherein the optical fiber collimators are four optical fibers collimators, and the reflective mirror is a reflector made of materials of which the surfaces are coated with reflecting films. The optical fiber transmits from PORT1 to PORT8, PORT2 to PORT7, PORT5 to PORT4 and PORT6 to PORT3. When the reflective mirror C is cut in between two four optical fibers collimators A and B, the optical fiber transmits from PORT1 to PORT4, PORT2 to PORT3, PORT5 to PORT8 and PORT6 to PORT7, and thus, functions of two 2*2 light switches are obtained on a space with a 2*2 light switch.

Description

Two 2 * 2 mechanical type multimode optical switchings

Technical field

The utility model relates to a kind of photoswitch, particularly relates to two 2 * 2 mechanical type multimode optical switchings of integrated 22 * 2 light switch function of a kind of mixing.

Background technology

In optical-fibre communications, photoswitch is as important element in the passive device, can be widely used in the field such as add drop multiplex, optical cross connect system, optical network protection of reconfigurable optical wavelength.2 * 2 photoswitches commonly used at present, its optical texture generally are made up of a pair of double-fiber collimator and middle catoptron; Or four collimating elements and middle reflection unit composition thereof.Such device can be finished the function of one 2 * 2 photoswitch.But when needing to use two even a plurality of handoff functionality as 2 * 2 photoswitches in the system, need to increase a plurality of inputs, output block even increased a plurality of catoptrons and realize in these designs, make complex structure make the volume of product increase, reduced the reliability in the work and increased cost.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides that a kind of volume is little, dependable performance, two 2 * 2 mechanical type multimode optical switchings that cost is low.

The technical scheme that the utility model adopted is: the utility model comprises housing, current-collector, two optical fiber collimators and is with the lever arm of reflective mirror, described optical fiber collimator is four optical fiber collimators, the catoptron that described reflective mirror is made up of the material of surface plating reflectance coating.

The assembly that described four optical fiber collimators are made up of one four line optical fiber head, collimation lens, metal tube or glass tube.

Described four optical fiber collimators also can be by one four line optical fiber head, a collimation lens, a glass tube and the assembly that metal tube is formed.

Described catoptron is the material of two sides plating highly reflecting films, or the material of face plating anti-reflection film, another face plating highly reflecting films, or the material of face plating highly reflecting films, another face coating ahsorption membrane.

The beneficial effects of the utility model are: because optical fiber collimator of the present utility model is four optical fiber collimators, so can with the same volume size of one 2 * 2 photoswitch under realized the function of 22 * 2 photoswitches, can avoid simultaneously because of using the problem of the functional reliability difference that a plurality of parts produce; When the utility model is applied to multimode network, less demanding when therefore assembling because under the multimode condition, the collimating apparatus receiving light path is insensitive to angle to the position repeatability of catoptron, control easily during actual production.So the utility model has embodied the advantage that reduces the space, reduces cost in multimode network.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the utility model comprises the lever arm 3 of housing 1, current-collector 2, two optical fiber collimator A and B, band reflective mirror C.Four optical fiber collimators that described optical fiber collimator A and B are made up of one four line optical fiber head 4, collimation lens 5, metal tube 6 and glass tube 7, can certainly be by one four line optical fiber head 4, collimation lens 5, four optical fiber collimators that metal tube 6 is formed, or by one four line optical fiber head 4, collimation lens 5, four optical fiber collimators that glass tube 7 is formed; The catoptron that described reflective mirror C is made up of the material of two sides plating highly reflecting films, also the catoptron that can be made up of the material of face plating anti-reflection film, another face plating highly reflecting films can also be the catoptron of the material composition of face plating highly reflecting films, another face coating ahsorption membrane.Just formed the Push And Release of photoswitch when reflective mirror C cuts under the drive of lever arm 3 or withdraw between two four optical fiber collimator A and the B, the incision of catoptron C realizes with withdrawing from by the assembly of relay E and lever arm D.The principle of relay and lever arm is identical with prior art.

When reflective mirror C does not cut between two four optical fiber collimator A and the B, from the light of optical fiber PORT 1 incident through four optical fiber collimator A after PORT 8 outgoing from four optical fiber collimator B; From the light of optical fiber PORT 2 incidents through four optical fiber collimator A after PORT 7 outgoing from four optical fiber collimator B; From the light of optical fiber PORT 5 incidents through four optical fiber collimator B after PORT 4 outgoing from four optical fiber collimator A; From the light of optical fiber PORT 6 incidents through four optical fiber collimator B after PORT 3 outgoing from four optical fiber collimator A; Promptly from PORT 1 → PORT 8; PORT 2 → PORT 7; PORT 5 → PORT 4; PORT6 → PORT 3.

When between two four optical fiber collimator A of reflective mirror C incision and the B, be mapped on the catoptron C after from the light of optical fiber PORT 1 incident through four optical fiber collimator A, the mirror C that is reflected reflects back into four optical fiber collimator A, PORT 4 outgoing from four optical fiber collimator A; In like manner return PORT 3 outgoing the four optical fiber collimator A from the light of the optical fiber PORT 2 incidents mirror C that is reflected after through four optical fiber collimator A; Return PORT 8 outgoing the four optical fiber collimator B from the light of the optical fiber PORT 5 incidents mirror C that is reflected after through four optical fiber collimator B; Return PORT 7 outgoing the four optical fiber collimator B from the light of the optical fiber PORT 6 incidents mirror C that is reflected after through four optical fiber collimator B; Promptly from PORT 1 → PORT 4; PORT 2 → PORT 3; PORT 5 → PORT 8; PORT 6 → PORT 7.

Optical fiber in the utility model four line optical fiber heads 4 is distributed with two kinds of situations in optical fiber head: a kind of is to make two vertical center lines with the center in optical fiber head cross section, with optical fiber along a center line setting wherein and be symmetrically distributed in the both sides of another center line; Another kind is that the center with the optical fiber head cross section is the center of circle, and optical fiber evenly is arranged on some circumferences in the optical fiber head cross section.

The utility model has just obtained the function of 22 * 2 photoswitches on one 2 * 2 light opens the light big or small space.All use multimode optical fiber to constitute optical fiber head during practical application, so just obtained two 2 * 2 multimode optical switchings.
