scope:

This specification covers the general requirements for removable crimp and epoxy type fiber optic termini for use in connectors and other fiber optic components (see 6.1). These termini are capable of operating within the temperature ranges as specified (see 3.1).

The application of specific termini shall be defined by the connector in which they are to be used, as specified herein (see 3.8) and in the applicable specification sheet (see 3.1).

Termini covered by this specification shall be of the following classes as specified (see 3.1).

a. Class 1 - Maximum operating temperature +71°C. Minimum operating temperature −46°C.

b. Class 2 - Maximum operating temperature +85°C. Minimum operating temperature −55°C.

c. Class 3 - Maximum operating temperature +105°C. Minimum operating temperature −55°C.

d. Class 4 - Maximum operating temperature +125°C. Minimum operating temperature −55°C.

e. Class 5 - Maximum operating temperature +150°C. Minimum operating temperature −65°C.

Termini covered by this specification shall be of the following types as specified (see 3.1).

a. Type I - Crimp

b. Type II - Adhesive

Termini covered by this specification shall be of the following styles as specified (see 3.1).

a. Style A - Butt

b. Style B - Expanded beam

The size of the termini shall be defined by the fiber size it can accommodate and the cavity size for which it is intended, as specified herein (see 3.8) and in the individual specification sheet (see 3.1). Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander Defense Electronics Supply Center ATTN: DESC-ES 1507 Wilmington Pike Dayton, Ohio 45444-5276, by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

This appendix is utilized to relate the termini identification color code (TICC) to an actual description of the PIN specified in MIL-T-29504A. This appendix is a mandatory part of the specification. The information contained herein is intended for compliance.

The purpose of this test procedure is to determine the total runout tolerance of the mating end of the fiber optic termini relative to the aligning surface (see figure 3). This appendix is a mandatory part of the specification. The information contained herein is intended for compliance.
