The OptiXaccess EA5801E-FL16 provides Flex-PON access, and supports passive optical LAN (POL) and fiber to the home (FTTH) solutions. It carries all services over one fiber network, simplifying network architecture and reducing OPEX. Figure 1-1 shows the basic structure of a PON. They transmit data at a high rate. Passive optical network (PON) technology is a new point-to-multipoint optical access technology. A PON network uses only optical fibers. Laser working status of the optical module on the EPON interface. Auto: indicates that the optical module generates optical signals when data needs to be transmitted and stops generating optical signals when no data needs to be transmitted. Simplifies power supply configuration and.
