37、201462074-1 IEC:2014(E) 7 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC WDM DEVICES Part 1: Generic specification 1 Scope This part of IEC 62074 applies to fibre optic wavelength division multiplexing (WDM) devices. These have all of the following general features: they are

38、passive, in that they contain no optoelectronic or other transducing elements; however they may use temperature control only to stabilize the device characteristics; they exclude any optical switching functions; they have three or more ports for the entry and/or exit of optical power, and share opti

39、cal power among these ports in a predetermined fashion depending on the wavelength; the ports are optical fibres, or optical fibre connectors. This standard establishes uniform requirements for the following: optical, mechanical and environmental properties. 2 Normative references The following docu

40、ments, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

45、e optical power 3.1.2transfer matrix optical properties of a fibre optic wavelength-selective branching device can be defined in terms of an n x n matrix of coefficients, where n is the number of ports, and the coefficients represent the fractional optical power transferred between designated ports

46、Note 1 to entry: A detailed explanation of the transfer matrix is shown in Annex A. The ports are numbered sequentially, so that the transfer matrix is developed to show all ports and all possible combinations. The port numbering is arbitrary. Note 2 to entry: Figure 1 below shows an example of a si

47、x-port device, with two input ports and four output ports. This WDM device can operate as four input ports and two output ports for their reciprocity characteristics. Also, it shall be noted that a combination of input and output port number can be selected, for example, 1 input port and 5 output po

48、rts, 3 input ports and 3 output ports and so on, especially for bi-directional transmission system application. Refer to Annex B. Outputs Inputs 1 4 2 5 6 3 IEC 0069/14 Figure 1 Example of a six-port device, with two input and four output ports Note 3 to entry: If there are four operating wavelength
