Optical Light Source and Optical Power MeterĪn optical light source is one of the most essential tools for technicians to install or maintain fiber optic networks. Because of the high-intensity laser light source, neither the light source nor the fiber core can be directly seen with naked eyes. When using a visual fault locator for fiber continuity testing, eye protection needs to be emphasized. The light source emitted by the visual fault locator can be used to identify and locate fiber link faults during testing, such as fiber bends, breaks, and faulty connections. It is a visible laser that delivers visible light into the fiber, enabling fiber identification from one end to the other end. The fiber continuity of MTP/MPO cables can be tested with a visual fault locator. Inspection and cleaning need to be performed on both ends, every time MTP/MPO cables are connected. If they are still not clean, a followed wet cleaning procedure with cleaning wipes or foam swabs can be used to ensure no residue is left on the endface. If the MTP/MPO connectors are dirty, clean them with dry cleaning tools first, such as a cassette cleaner and an MTP/MPO pen cleaner. MTP/MPO connectors are very sensitive to dirt and contamination, requiring rigorous inspection and cleaning before testing.Įssential is a high-quality microscope to check the connectors and components.

The importance of cleanliness in fiber testing cannot be overemphasized.

Following these basic MTP/MPO patch cord testing best practices will result in more reliable and efficient network deployments. Testing MTP/MPO fiber cables makes a significant contribution to the performance, reliability, and manageability of the cabling system. For example, here are the USConec specifications for MPO connectors, which can be used to measure the performance of the tested connectors.

TIA/EIA has developed significant national stands for fiber optic test networks and equipment, such as fiber installation certification requirements for length, polarity, and link loss.īesides, specifications for MTP/MPO patch cords can be used as a reference for test results. IEC is a global standards organization that has established recognized international standards for fiber geometry, attenuation, macro bending loss, and chromatic dispersion. The following are well-known standards bodies that can guide testing MTP/MPO fiber optic patch cords. Before testing, it is necessary to determine the standards to be followed for fiber optic cables, which facilitates performance measurement of cables by comparison. Standards Complianceįiber optic industry standards are constantly evolving, setting specific standards for fiber types (OM3, OM4, OS2, etc), cable types (fire retardance, bend resistance, etc), connectors (LC, MPO/MTP), optical safety, and other aspects. This article will focus on the standards and specific test methods for MTP/MPO fiber optic cables. To ensure optimal performance of MTP/MPO cabling system, it is necessary to test MTP/MPO cables.

MTP/MPO fiber patch cords effectively improve network stability and sustainability and are widely used in high-speed and high-density data center cabling. The 5G network, FTTX (Fiber to the X), and IoT (Internet of Things) accelerate the development and expansion of fiber optic networks, increasing the demand for fiber optic cables.
