3、standings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for their particular need. The existence of such Publications shall not in any respect preclude an
4、y member or non-member of TIA from manufacturing or selling products not conforming to such Publications. Neither shall the existence of such Documents preclude their voluntary use by non-TIA members, either domestically or internationally. TIA DOCUMENTS TIA Documents contain information deemed to b
5、e of technical value to the industry, and are published at the request of the originating Committee without necessarily following the rigorous public review and resolution of comments which is a procedural part of the development of a American National Standard (ANS). Further details of the developm
6、ent process are available in the TIA Engineering Manual, located at http:/www.tiaonline.org/standards/sfg/engineering_manual.cfm TIA Documents shall be reviewed on a five year cycle by the formulating Committee and a decision made on whether to reaffirm, revise, withdraw, or proceed to develop an Am
7、erican National Standard on this subject. Suggestions for revision should be directed to: Standards see TIA/EIA 604. 1.3 Limitations Realization of the objectives for FOCIS 17 may be limited by the following considerations: 1.3.1 Configuration options There are configuration options for both plugs a
8、nd adaptors in FOCIS 17 that impose limitations on the combinations of plugs and adaptors that should be selected in a connector assembly. ? Both plugs should have the same ferrule diameter option, t. An assembly with different diameter options may have a higher loss than anticipated. ? Both plugs s
9、hould have the same angle of contact option a. An increase in loss may be expected if the plugs with different options are mated, and the polish on the ferrule may be damaged.

The location of the fiber c
11、ores, figure 3.2.6, and the apex offsets, clause 3.2.4, are defined, without tolerances, by their true positions. To achieve common performance, the distributions of the actual positions of these features should be centered on their respective true positions. ? Tuning of the connector plugs may impr
12、ove performance when plugs are mated with plugs that have been similarly tuned. Tuned plugs, o=1, are assembled so the fiber core of the plug falls in a preferred location with respect to the key; see clause 3.2.6. The common level of performance of connector plugs that have been tuned shall be base
13、d on their untuned performance; see TIA/EIA 604, section 7. ? This standard does not control the intrinsic loss that may occur between fibers in a connector assembly. Intrinsic loss between fibers must be added to the basic connector loss. 1.3.3 Resolution Cases of combinations of plugs and adapters
14、 where mechanical intermateability or the common level of performance is not achieved should be resolved through the cooperation of the user and the connector and adapter manufacturer(s). 1.4 Drawing practices To be in compliance with ANSI and ISO Engineering Drawing Practices, the following shall a
15、pply: 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 may not exceed the envelope of perfect form at the maximum material condition (MMC). 2. Where interrelated features o
16、f 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 tolerance as well as the size. When interrelated features are at the MMC they shall be perfectly located to each oth
17、er 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 dimensions for a feature control the orientation tolerance as well as the size. When perpendicular features are at the MM
18、C 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 permissible. 2 ADAPTER STANDARD 2.1 Adapter designation The designation for a FOCIS 17 adapter is: FOCIS 17A-d-n-m where Co

21、igure 2.2.1a Simplex Adapter Interface d=1, n=2 - Figure 2.2.1b, Duplex Adapter Interface, separated plug arrangement, plugs arranged based on 6.25 mm center to center spacing. d=2, n=2 - Figure 2.2.1c, Duplex Adapter Interface, dense plug arrangement, plugs arranged based on 4.5 mm center to center
22、 spacing. 2.2.2 Adapter sleeve The adapter sleeve may be a split (resilient) sleeve, and the sleeve may be either fixed or floating within the adapter. 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 ga
23、ge pin from the sleeve in a FOCIS 17 adapter shall be 1.0 N (Newton) to 2.5N. The procedures of FOTP 158 shall be used to measure the withdrawal force. Gage pin diameters are specified in table 1. Table 1 - Gage pin diameters Sleeve Type Minimum Diameter (mm) Maximum Diameter (mm) Split, Resilient 1
24、.2485 1.2495 The maximum inside diameter of the sleeve is in effect limited by the common level of performance that the adapter is to achieve. The surface roughness of the gage pin should be grade N4 (0.2 m radius). 2.2.3 Adapter mounting options The adapter mounting options specified is m=0. The mo
