Description

INTRODUCTION

Intent.¹ The intent of this test is to demonstrate
the ability of a fiber optic component device-to-cable
attachment(s), and any interface area of mated component device
seals, to perform satisfactorily during, and subsequent to,
simulated rapid descents from high altitude, with attendant
moisture condensation. Typically, fiber optic interconnecting
devices are most commonly tested by this method, but the
methodology can be applied to various other types of fiber optic
components.

Alternative Method. This test is similar to
that prescribed by FOTP-190, except that specimens tested under
FOTP-190 are not immersed in water during low pressure exposure.
Also , FOTP-190 provides a wider choice of test pressures than does
FOTP-15.

Failure Modes. The potential failure modes for
this test include, but are not limited to:

a. Unacceptable changes in optical transmittance,

b. Unacceptable changes in insertion loss,

c. Unacceptable changes in return loss,

d. Damage to device seals.,

e. Other failure modes (such as changes in engagement and
separation forces) may be specified by the Detail
Specification.

¹This method is similar to Method 1004.1 of
MIL-STD-1344. However, the MIL-STD requires immersion in a salt
solution, while this method uses distilled water immersion
only.
