Fiber Testers: What You Need to Know before you buy!

Whether it’s outside plant (OSP) infrastructure, links between equipment in the data center, or the backbone in a LAN, a light source and power meter (LSPM) test set is the most vital of all tools for testing an installed fiber plant. Most specifications require Tier 1 testing per TIA and ISO standards using an LSPM to calculate total insertion loss and length. And even if a specification calls for Tier 2 testing, which requires an optical time domain reflectometer (OTDR) for determining insertion loss and reflection of individual connection points, final insertion loss testing still needs to be done with an LSPM test set that provides the most accurate overall channel loss testing.
