10、nation FIBER JACK, and is issued as an addendum to TINEIA 604, Fiber Optic Connector Intermateability Standard. The provisions of TINEIA 604 apply to this document. 1.2 Objective The requirements in FOCIS 6 have been selected with the objective of ensuring that any combination of plugs and sockets c
11、onforming to the requirements of FOCIS 6 will mechanically intermate, and that intermated connector assemblies will meet their common level of performance. Intermateability standards define the minimum physical attributes of mating connector components. Fully dimensioned components are not within th
12、e scope or intent of FOCIS 6. The common level of performance of an intermated connector assembly is the least demanding set of performance requirements in the separate performance specifications of each of the products in the assembly; see TINEIA 604. The following factors, however, shall be consid
13、ered in the application of common performance: 1. Common performance does not account for intrinsic loss between the fibers; see TINEIA 604, section 6. 2. The common level of performance of connector plugs that have been tuned shall be based on their untuned Performance; see TINEIA 604, section i. T
14、here are also limitations based on the options that are available: 1. Ferrule Diameter - Both the plug and the socket in a connector assembly shall have the same ferrule diameter option. 2. Keying - The keying arrangement for the plugs in a connector assembly shall be compatible with the keying arra
15、ngement for the socket. 1 3. Contact Angle - Both plugs and sockets in a connector assembly shall have the same contact angle. Cases of combinations of plugs and sockets where mechanical intermateability or the common level of performance is not achieved should be resolved through the cooperation of
16、 the user and the respective component manufacturer(s). 1.3 Drawing practices To be in apply: 1. 2. 3. 4. compliance with ANSI and IS0 Engineering Drawing Practices, the following shall Where a tolerance of form is not specified, the limits of the dimensions for a feature control the form as well as
17、 the size. The combined effects of size and form variations may not exceed the envelope of perfect form at the maximum material condition (MMC). Where interrelated features of size (features shown with a common axis or center plane) have no geometric tolerance of location or run out specified, the l
18、imits of the dimensions for a feature control the location tolerance as well as the size. When interrelated features are at the MMC they shall be perfectly located to each other as indicated by the drawing. Where perpendicular features (features shown at right angles) have no geometric tolerance of
19、orientation or run out specified, the limits of the dimensions for a feature control the orientation tolerance as well as the size. When perpendicular features are at the MMC they shall be perfectly oriented to each other as indicated by the drawing. As the size of a feature departs from the MMC, va
20、riations in form, location and orientation are permissible.

23、igned in either a sleeve or a bore. The sleeve may either be solid or split (resilient), and the sleeve may be either fixed or floating within the socket. The inside diameter of the sleeve or bore of the socket is determined by the ferrule diameter option of the socket. Table 1 Sleeve Inside Diamete
24、r (mm) 3 Notes: A) The minimum inside diameter of the sleeve is specified by the force required to remove a gage pin from the sleeve. The force required to remove a gage pin from the sleeve in a FOCIS 6 socket shall not exceed 5.89 Newton (600 gmf). The procedures of FOTP-158 shall be used to measur
25、e the withdrawal force. The gage pin diameter will be a minimum 2.4985 mm and a maximum 2.4995 mm for split (resilient) sleeves. The gage pin diameter will be 2.5000 to 2.5005 for solid sleeves. 6) The maximum inside diameter of the sleeve is in effect limited by the common level of performance that
26、 the socket is to achieve. C) Plastic Optical Fiber (POF) standards have been proposed for development by the TIA. 2.2.3 Number of fibers option Only a dual fiber socket, n=2, has been defined for FOCIS 6. 2.2.4 Socket mounting option The only mounting option specified is m=O. The mounting features
27、for this option are undefined. 2.2.5 Socket keying option Only a single keying option for FOCIS 6 sockets has been defined, k=7. 2.2.6 Ferrule option diameter If ferrules are used to secure the fibers in the socket to the optical reference plane, see Table 2 in section 3.2.3 for ferrule option diame
28、ters. When the fiber alignment mechanism of the socket is a split sleeve, ferrules shall be used. 2.2.7 Angle of contact option The contact angle is the angle between the plane of contact between mating fibers and a plane perpendicular to the optical axis of the socket. a=O, designates an angle of O
29、“ The only angle of contact option for FOCIS 6 sockets is a=O. 2.2.8 Fiber position and end geometry The fiber end surfaces in the socket shall be fixed at the optical reference plane as shown in Figures 2.2.1a, 2.2.lb and 2.2.1. When split sleeves are used for alignment, socket fibers shall be term
30、inated in ferrules as illustrated in Figures 2.2.la and 2.2.1. When split sleeves are not used, the fibers may be terminated in ferrules or other elements of the socket. 4 The following general conditions apply to the termination of the fibers in the socket: GOF The end of the fibers are to be nomin
31、ally flush with the surrounding area. The fiber and surrounding area may be flat or radiused (convex). POF The fiber endface is flat within .O10 mm and perpendicular to the fiber axis within +/- 2.0“. The fiber may project beyond the surrounding area of the supporting structure. 2.2.9 Socket Tuning
32、It is not required that the sockets be tuned; if, however, a socket is tuned, the orientation of the eccentricity of the core is to be located as shown in figure 2.2.9. Tuning of the socket is the preferential angular positioning of the ferrule relative to the key of the socket. 5 STDmEIA TIA/EIA-bO

The requirements for these interfaces are: d= The design requirement on the elements of the plug
35、that control the interface with the socket is that the plugs function with all sockets that meet requirements for FOCIS 6 sockets. The elements of the plug that control the interface with the socket, for plugs offered under this option, must meet the dimensional requirements of figure 3.2.1. d=7 3.2
36、.2 Ferrule extension and contact force The travel of the ferrule, relative to the body of the plug, and the spring force of the ferrule are defined in Figure 3.2.2. 3.2.3 Ferrule diameter option The ferrule diameter option defines the diameter of the ferrule in the plug for each type of fiber termin
37、ated in the plug. Ferrule diameter options for FOCIS 6 plugs are specified in Table 2.
