Impact Resistance – Fiber Optic Cable

Fiber optic impact testing is a used to assess the resilience and durability of fiber optic cables when subjected to impact or mechanical stress. It involves subjecting the cable to various impacts or mechanical forces to evaluate its ability to withstand such events without experiencing significant damage or performance degradation. During fiber optic impact testing, […] Read more

Attenuation – Fiber Optic Cable

Fiber optic cable attenuation testing is a procedure performed to measure the loss of signal strength or power as it travels through a fiber optic cable. Attenuation refers to the decrease in the intensity of light signals as they propagate along the fiber. The purpose of attenuation testing is to assess the quality and performance […] Read more

Moisture Resistance

MIL-DTL-3885 Method 4.6.4 specifies the moisture resistance test for wire and cable connectors. This test is conducted to evaluate the ability of connectors to withstand exposure to moisture and ensure their reliability in humid or wet environments. The test is designed to simulate the effects of moisture on the connectors and assess their performance under […] Read more

Vibration

Connectors are exposed to high vibration environments on aircraft and should be capable of tolerating these environments. A MIL-DTL-26482 compliant connector shall tolerate random vibration from 10 to 2,000Hz at 10 microseconds of maximum discontinuity. Read more

Resistance to Electrical Arcs

When wires are damaged in in service electrical arcing may occur, current “jumping” across a gap that would normally be insulated buy distance or an insulating material. This electrical activity can further damage the wire and potentially damage surrounding wires, cables, equipment, structure, and fuel lines. Arcing is often associated with severe electrical failure and […] Read more

Resistance to Flame Propagation

This test evaluates the ability of cable insulation to resist flame propagation when exposed to fire; for a high quality cable insulation, the flame should extinguish quickly and not spread along the length of the cable. A flame is applied to a finished cable affixed in the test apparatus and maintained for 30 seconds. Upon […] Read more

Relative Thermal End Point Time and Temperature Index

The chemical composition of a wire’s insulation degrades at elevated temperature; this test provides data to establish curves describing the rate of degradation with respect to the exposure temperature. Samples are divided into four groups; each group is exposed to a selected temperature for defined time intervals. The time intervals are determined by an estimate […] Read more

Resistance to Hot Water

This test evaluates the ability of a wire or cable to withstand extended exposure to hot water while connected to a relatively low voltage source. A coiled test sample is secured into a saltwater bath maintained at 85 degrees Celsius; both exposed ends of the sample remain outside he water bath. One exposed end is […] Read more

RF High Potential Withstanding Voltage

This test measures the ability of a high frequency connector to withstand a specified RF voltage and frequency. The connector is mated to the appropriate receptacle and connected to the test circuit. A specified RF voltage and frequency are applied between the center contact and the connector body, stabilized, and maintained for one (1) minute. […] Read more

Shell to Contact Resistance

This test measures the resistance between each grounding contact and the shell of a connector. This quality is imperative to the functionality of the connector as current leakage between contacts and the shell can lead to severe malfunction. The voltage drop is measured between each grounding contact and the shell while carrying a one (1) […] Read more
