Error Standards for Optical Cable Segments
The International Electrotechnical Commission (IEC) and the Telecommunications Industry Association (TIA) create detailed rules for fiber optic components, manufacturing, and testing. The fiber optic link attenuation is tested using an optical loss test set (OLTS) or a light source and power meter (LSPM) Figure 1). This type of testing is the most accurate testing available and is the most accurate characterization of the fiber optic system's apability. Premises cabling systems look like the photo to the right, where the backbone fiber is terminated in wiring closets and short. This document outlines the procedure recommended by Panduit for field permanent link loss testing of multimode and singlemode structured cabling systems. As the components like fiber, connectors, splices, LED or laser sources, detectors and receivers are being developed, testing confirms their performance specifications and helps.

Does the PON switch have an optical port
The PON port is like the main gate on the ONU (Optical Network Unit), connecting it to the Optical Distribution Network (ODN). A passive optical network (PON) or Gigabit Passive Optical Network (GPON) is a point-to-multipoint (P2MP) network that uses a combination of active transmission equipments and passive cable components to provide network connectivity to end user's devices. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. This unique architecture enables PONs to offer several key benefits, including Reduced operating and management costs.
