The provisions of TIA/EIA 604 apply to this document 1.2 Objective Intermateability standards define the minimum physical attributes of mating connector components. Fully dimensioned components are not within the scope or intent of FocIs 10A The requirements in FoCIS 10A have been selected with the objective of ensuring that any combination of plugs and adapters conforming to the requirements of FOCIS 10A will mechanically intermate, and that intermated connector assemblies will meet a common level of performance 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 TIA/EIA 604 1.3 Limitations Realization of the objectives for FoCIS 10A may be limited by the following considerations 1.3.1 Configuration Options There are configuration options for both plugs and adapters in Focis 10A that impose limitations on the combinations of plugs and adapters that should be selected in a connector assembly For plugs to be inserted in the adapter, the key option, k, for both plugs must be compatible with the keying option of the adapter 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 should 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. COPYRIGHT Electronic Industries alliance Licensed by Information Handling services T|AE|A-604-10A 1.3.2 Common performance The following considerations limit the application of common performance The location of the optical cores, figure 3. 2.3a, and the apex offsets, clause 3.2.5 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 improve performance when plugs are mated with plugs that have been similarly tuned. Tuning, however, offsets the cores relative to the center of the ferrule and common performance can not be expected between tuned plugs and untuned plugs. Tuned plugs are assembled so the offset of the fiber falls in a preferred location with respect to the key; see clause 3. 8. As an alternative to tuning for fiber offset, plugs could be tuned for apex offset 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 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 Practices, the following shall apply 1. Where the 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 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 tolerance as well as the size. When interrelated features are at the MMC, they shall be perfectly located relative to each other as indicated by the drawing 3. Where perpendicular features (features shown at right angles) have no geometric tolerance of orientation or runout specified, the limits of the dimensions for a feature control the orientation tolerance as wel 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 permissible COPYRIGHT Electronic Industries alliance Licensed by Information Handling services T|AE|A-604-10A 2 Adapter Standard 2. 1 Adapter designation The designation for Focis 10a adapter is FOCIS 10A-A-n-k-m where A designates an adapter nkm is the number of fibers defines the keying configuration defines the mounting configuration 2.2 Adapter requirements FoCIS 10A adapters shall meet the requirements of this section 2.2. 1 Adapter interface dimensions The dimensional requirements for Focis 10A adapters are defined as follows n=1 Figure 2. 2. 1a, Simplex adapter interface and Figure 2.2. 1b Simplex junior adapter interface n=2 Figure 2.2.1c, Duplex adapter interface 2.2.2 Adapter sleeves The adapter sleeve is a split (resilient), 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 a sleeve. The force required to remove a gage pin from the sleeve in FoCIS 10A adapter shall be 1.0N to 2. 5N. The procedures of FoTP 158 shall be used to measure the withdrawal force. The pin gauge shall be as defined in Figure 2.2.2 The maximum inside diameter of a sleeve is in effect limited by the common level of performance that the adapter is to achieve 3 COPYRIGHT Electronic Industries alliance Licensed by Information Handling services T|AE|A-604-10A 2.2.3 Adapter keying options Keying refers to differences in the interface between FocIS 10A plugs and adapters that affect the ability of plugs and adapters to be connected or that alter the performance of the resulting connector assembly The keying interfaces have been defined k=1 Figure 2.2.1a, Senior Adapter Half k=2. Figure 2.2. 1b Junior Adapter Half Adapters can be made with either, k= 1 and k =1 adapter halves or k= 1 and k=2 adapter halves. Adapters with k 1 and k= 2 is mounted so the k= 2 half is mounted behind the panel protected from mechanical elements. Adapter with k=2/k=2 option is not recognized as focis 10A compliant 2.2.4 Adapter mounting options The adapter mounting options are defined in Table 2 Table 2-Adapter options Adapter Type of mounting Mounting Option Unspecified mounting 01234 Simplex Snap-in Flange Mounting Duplex Snap-in Flange Mounting Duplex Snap-in Flange Mounting compatible with FOCIS 3A m=3 m=4 Duplex snap-in Flange Mounting compatible with Focis 3a m= 1 and m= 2 Adapters whose mounting features are not defined are identified with the option m=0 The dimensions of the surfaces of the adapter that interface with the mounting panel are defined by the cutouts in the panel on which the adapter is mounted FOCIS 10A adapters for m=1, m=2, m=3, and m= 4 shall be capable of being mounted on panels with the dimensions in Figure 2. 2. 4 COPYRIGHT Electronic Industries alliance Licensed by Information Handling services
