GPON | EPON Network Construction and Maintenance Tester

The FE ParaScope PON Advanced Test Set for GPON/EPON Network Construction and Maintenance

The Frederick Engineering ParaScope PON measures the power of GPON/EPON circuits and can test three wavelengths (1490nm, 1550nm and 1310nm) simultaneously. FE provides a wide range of cost-effective network management, security, and analysis products for fiber, 10/100/Gigabit, VoIP, wireless, and wide area networks. From handheld test tools for field service technicians to enterprise-wide analyzers for network managers, FE has the best solution to meet your network requirements.

ParaScope PON

Who is Frederick Engineering?

Frederick Engineering (FE) is the leading provider of network testing products and solutions, which are used globally for installing, troubleshooting, managing, and securing networks. Founded in 1983, FE provides ideal solutions with their world-renowned ParaScope product line. Their products include PC-based, remotely-operated, and handheld test products and are routinely used for analyzing and resolving network problems.

What is PON?

A PON (passive optical network) is a point-to-multipoint fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 16-128. A PON consists of an optical line terminal (OLT) at the service provider’s central office and a number of optical network units (ONUs) near end users. A PON reduces the amount of fiber and central office equipment required compared with point to point network architectures. Downstream signals are broadcast to all premises sharing multiple fibers, upstream signals are combined using a multiple access protocol, usually time division multiple access (TDMA). The OLTs “range” the ONUs in order to provide time slot assignments for upstream communication.

ParaScope PON measures the power of GPON/EPON circuits. Tests three wavelengths simultaneously: 1490nm, 1550nm and 1310nm.
