Abstract

PURPOSE:To mount optical fibers with low loss and large capacity by storing plural circuits obtained by butting the optical fibers on the same plane and butting the circuit optical fibers to connecting optical fibers. CONSTITUTION:An optical switch consists of transmission line fibers 6, transmission line fixing ferrules 14, a V-groove 15, transmission line fiber fixing ferrule pressing means 16, switching fibers 17, switching fiber fixing ferrules 18, and a ferrule fixing device 19. When the switching fiber fixing ferrules 18 fixing the switching fibers 17 are inserted with fixing device 19 into a space on the V- groove 15, a switching circuit can be set up by butting. Thus, the optical fibers can be mounted with low loss and large capacity.

If there are multiple transmission lines,
It is wasteful to add a source switch for each transmission path, so
An optical switch needs to accommodate multiple (N) transmission lines. Therefore, the function of the optical switch is one that is duplicated.
×N switch function is required. Here, "duplicated" means that it has an IXN switch function for both the transmitting side and the receiving side.

ＸＮスインチが実現できないという欠点があった。FIG. 3 shows the configuration of the switch line, where 11 is a movable fiber, 12 is a fixed fiber, and 3 is a fiber fixing device. Figure 3(a) shows a movable fiber 11 and a fixed fiber 1.
2. The fiber fixing device 13 is arranged as shown in the figure, and the movable fiber 1 is configured to form a line with the movable fibers 1 and 1. The switch line is made by fixing the movable fiber 11 as shown in Fig. 3(b) by the action of a magnet or the like. Movable fiber 1 by moving
1 and configuring a new line using the fixed fiber 12. In a fiber movable optical switch, connections are made by butting fibers together, so low connection loss can be achieved. However, with the configuration shown in Figure 2, a large-capacity IXN switch can be realized, but a duplex switch cannot be realized, and with the configuration shown in Figure 3, a duplex switch can be realized, but a 1x2 switch cannot be realized. With conventional movable fiber type optical switches, there is a limit to the duplex I
There was a drawback that the XN swing could not be realized.

数Ｎもある程度制限されるという欠点があった。On the other hand, such a duplex IXN switch can be constructed using a mirror or prism movable type optical switch, but with optical switches other than the optical fiber movable type, it is difficult to match input and output fibers, and it takes time. Since the spatial propagation of light enters the space, low connection loss cannot be achieved, and the number N of mountings is also limited to some extent.
