EXFO FOT-302 – Optical loss test set

The EXFO FOT-302 is an optical loss test set that is used to measure the amount of light loss in optical fibers. It is a handheld device that is designed for field use and is commonly used in the telecommunications industry. The FOT-302 is part of the FOT-300 series of optical loss test sets produced by EXFO. In this article, we will discuss the features and benefits of the FOT-302, its applications, and how it compares to other optical loss test sets.

Features and Benefits:

• The FOT-302 is a versatile device that offers up to three single-mode or two multi-mode wavelengths on a single port.
• It transmits with a wavelength-identification digital encrypted protocol, allowing for easy identification of the wavelength used.
• The device also has a built-in power meter and light source for bi-directional testing without technicians needing to exchange equipment.
• The FOT-302 is designed to be rugged and durable, making it ideal for use in the field.
• It has a long battery life, which allows for extended use without the need for recharging.
• The device is also lightweight and compact, making it easy to carry around.

Applications:

• The FOT-302 is commonly used in the telecommunications industry for testing the performance of optical fibers.
• It is used to measure the amount of light loss in optical fibers, which is an important parameter for ensuring the quality of the fiber optic network.
• The device is used to test the loss of optical fibers in both single-mode and multi-mode fibers.
• The FOT-302 is also used to test the performance of passive optical networks (PONs) at 1310 nm, 1490 nm, and 1550 nm, the three wavelengths recommended by the ITU-T (G).
