This document is part of the series of fiber optic connector intermate

20、ability standards included within TIA/EIA-604, Fiber Optic Connector Intermateability Standards (FOCIS). 1. INTRODUCTION 1.1 Scope FOCIS 7 presents the intermateability standard for connectors designated Type SG, and is issued as an addendum to TIA/EIA 604, Fiber Optic Connector Intermateability Sta

21、ndards. The provisions of TIA/EIA 604 apply to this document. 1.2 Objective The requirements in FOCIS 7 have been selected with the objective of ensuring that any combination of Plugs and Sockets conforming to the requirements of FOCIS 7 will mechanically intermate, and that intermated connector ass

22、emblies will meet their common level of performance. Intermateability standards define the minimum physical attributes of mating connector components. Fully dimensioned components are not within the scope or intent of FOCIS 7. The common level of performance of an intermated connector assembly is th

23、e least demanding set of performance requirements in 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 lo

24、ss between the fibers being joined; see TIA/EIA 604, section 6. There are also limitations based on the options that are available. 1. Fiber Diameter - Single-mode fibers have an established diameter tolerance conforming to a TIA product specification. Multimode fibers have an established diameter t

25、olerance conforming to a TIA product specification. Both plug and socket fiber shall be in the same diameter tolerance category. TIA-604-7A 2 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 - Bo

26、th fibers 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 the user and the connector plug and socket manufacturer(s

27、). 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 specified, the limits of the dimensions for a feature control the form as well as the size. The combined effects of size and form variations ma

28、y 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 center plane) have no geometric tolerance of location or runout specified, the limits of the dimensions for a feature control the location t

29、olerance 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 perpendicular features (features shown at right angles) have no geometric tolerance or orientation or runout specified, the limits of the dimens

30、ions 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. 4. As the size of a feature departs from the MMC, variations in form, location and orientation are permissi
