The loss of signal, which occurs along the length of a fiber optic link, is called insertion loss, and insertion loss test is for measuring the losses of light appears in fiber optic core and fiber optic cable connections. The measurement of the amount of light that is reflected back toward the source is called return loss test. and insertion loss and return loss are all measured in decibels(dBs).
Regardless of type, when a signal travels through a system or a component, power (signal) loss is unavoidable. When light passes through the fiber, if the loss is very small, it will not affect the quality of the optical signal. The higher the loss, the lower the amount reflected. Therefore, the higher the return loss, the lower the reflection and the better the connection.

Fiber optic core reflection test is proceed by Optical Time Domain Reflectometer (OTDR). Which is a device used to precisely detect faults in an optical fiber link of a communication networks. An OTDR generates a pulse inside a fiber to be tested for faults or defects. Different events within the fiber create a Rayleigh back scatter. Pulses are returned to the OTDR and their strengths are then measured and calculated as a function of time and plotted as a function of fiber stretch. The strength and returned signal tell about the location and intensity of the fault present. Not only maintenance, but also optical line installation services utilize OTDRs.
OTDR is useful for testing the integrity of fiber optic cables. It can verify splice loss, measure length and find faults. The OTDR is also commonly used to create a “picture” of fiber optic cable when it is newly installed. Later, comparisons can be made between the original trace and a second trace taken if problems arise. Analyzing the OTDR trace is always made easier by having documentation from the original trace that was created when the cable was installed. OTDR show you where the cables are terminated and confirm the quality of the fibers, connections and splices. OTDR traces are also used for troubleshooting, since they can show where breaks are in fiber when traces are compared to installation documentation.
Jera proceed test of FTTH drop cables on wavelengths (1310,1550 and 1625 nm). We use EXFO FTB-1 in this quality tests. Examining the quality of our cables to ensure ours customer could receive products which meet quality requirements.

Temperature and humidity cycling test is used to test and determine the parameters and performance of products or materials through the changes of the temperature and humidity such as under high temperature and humidity or low temperature and humidity.
Environmental changes in things like temperature and humidity strongly influence material and product performance. We preform this test by immersing products or accessories in artificial environment, exposing products to extreme high temperature, gradually reducing to low temperature, and then returning to high temperature. This cycle can be repeated in the case of reliability testing or customers’ requirements.

Also some countries have continuous rainfall and high humidity just like the Philippines. We must make sure that our products can be applied in different weather conditions and this test can be a good examination for products’ performance.
Testing chamber simulate the different weather conditions, the adjustable temperature range of the equipment is +70℃~-40℃ and humidity range is 0%~100%, which covers most rugged environment in the world. We also can control the rate of temperature or humidity’s rise and fall. The test’s requirement of temperature or humidity could be preseted to avoid human mistake and ensuring the authenticity and accuracy of the experiment.
We do this test on new products before launching, also for the daily quality control.
