In the PON technology application, OLT equipment is an important local-end device, which achieves the following functions. connect with the front-end ( aggregation layer ) switch with network cable, convert into optical signal, and interconnect with the splitter at the. An optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network. Modern OLTs offer communication service providers (CSP) the ability to launch multigigabit services to tens of thousands of subscribers from a single location or just ten. This system facilitates multiplexing of data streams. The VCL-E3 & E1-OLTE is a 34Mbps & 2. 048Mbps Optical Line Transmission Equipment which converts and transports a ITU-T compliant standard E3, 34Mbps signal and E1, & 2. The optical link, between two OLTE terminals is established on one pair of optical fibers.

Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). The ground resistance between all system parts shall be <. The correct connection method of Distribution box grounding wire mainly includes the following steps: 1. The grounding "bus" (grounding bus, PE bus) in the box is directly connected to the power ground wire or grounding system; 2. Preparation: First, you need to prepare some necessary tools, including grounding wire, grounding rod, voltmeter, insulating gloves and insulating tools. The basic rule achieves this through an equipment grounding jumper; four exceptions. The National Electrical Code (NEC) lists eight specific methods to make grounding and bonding connections in Sec. Let's take a look at each one in more detail. **Test the grounding resistance**: Use a.
