15、STANDARD (FIBER JACK CONNECTOR) 1 INTRODUCTION 1.1 Scope FOCIS 6 presents the intermateability standard for connectors with the commercial designation FIBER JACK, and is issued as an addendum to TIA/EIA 604, Fiber Optic Connector Intermateability Standard. The provisions of TIA/EIA 604 apply to this
16、 document. 1.2 Objective The requirements in FOCIS 6 have been selected with the objective of ensuring that any combination of plugs and sockets conforming to the requirements of FOCIS 6 will mechanically intermate, and that intermated connector assemblies will meet their common level of performance
17、. Intermateability standards define the minimum physical attributes of mating connector components. Fully dimensioned components are not within the scope or intent of FOCIS 6. The common level of performance of an intermated connector assembly is the least demanding set of performance requirements i
18、n the separate performance specifications of each of the products in the assembly; see TIA/EIA 604. The following factors, however, shall be considered in the application of common performance: 1. Common performance does not account for intrinsic loss between the fibers; see TIA/EIA 604, section 6.
19、2. The common level of performance of connector plugs that have been tuned shall be based on their untuned performance; see TIA/EIA 604, section 7. There are also limitations based on the options that are available: 1. Ferrule Diameter - Both the plug and the socket in a connector assembly shall hav
20、e the same ferrule diameter option. 2. Keying - The keying arrangement for the plugs in a connector assembly shall be compatible with the keying arrangement for the socket. 3. Contact Angle - Both plugs and sockets in a connector assembly shall have the same contact angle. Copyright Telecommunicatio

22、on level of performance is not achieved should be resolved through the cooperation of the user and the respective component manufacturer(s). 1.3 Drawing practices To be in compliance with ANSI and ISO Engineering Drawing Practices, the following shall apply: 1. Where a tolerance of form is not speci
23、fied, the limits of the dimensions for a feature control the form as well as the size. The combined effects of size and form variations may not exceed the envelope of perfect form at the maximum material condition (MMC). 2. Where interrelated features of size (features shown with a common axis or ce
24、nter plane) have no geometric tolerance of location or run out specified, the limits 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. 3. Where perpe
25、ndicular features (features shown at right angles) have no geometric tolerance of 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 ot
26、her as indicated by the drawing. 4. As the size of a feature departs from the MMC, variations in form, location and orientation are permissible.

29、eeve The fibers may be aligned 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.

32、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 measure the withdrawal force. The gage pin diameter will be a minimum 2.4985 mm and a maximum 2.4995 mm for split (resilien
33、t) sleeves. The gage pin diameter will be 2.5000 to 2.5005 for solid sleeves. B) The maximum inside diameter of the sleeve is in effect limited by the common level of performance that the socket is to achieve. C) Plastic Optical Fiber (POF) standards have been proposed for development by the TIA. 2.
34、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=0. The mounting features for this option are undefined. 2.2.5 Socket keying option Only a single keying option for FOCIS 6 sockets has been de

When the fiber alignment mechanism of the socket is a split sleeve, ferrules shall be used. 2.2.7 Angle of cont
36、act 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=0, designates an angle of 0 The only angle of contact option for FOCIS 6 sockets is a=0. 2.2.8 Fiber position and end geometry The fiber end sur
37、faces in the socket shall be fixed at the optical reference plane as shown in Figures 2.2.1a, 2.2.1b and 2.2.1c. When split sleeves are used for alignment, socket fibers shall be terminated in ferrules as illustrated in Figures 2.2.1a and 2.2.1c. When split sleeves are not used, the fibers may be te

The fiber and surrounding area may be flat or radiused (convex). POF The fiber endface is flat within .010 mm and perpendicular to the fiber a

The fiber may project beyond the surrounding area of the supporting structure. 2.2.9 Socket Tuning 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 th
