Broadband networks

Design, construction and maintenance of structures of a passive optical network using PON technology

The main advantages of PON

• Absence of intermediate active nodes
• Savings of optical transceivers in the central node
• Saving of fibers
• High throughput
• Low damping factor
• Absence of electromagnetic effects
• Small size and small weight of optical cables
• High reliability of components
• The wide range and high quality of services
• Easy to connect new subscribers and serviceability
• Prospect of infrastructure
• Modern varieties of PON

• GPON - passive optical network that uses ATM technology and provides gigabit rates of data transfer
• GEPON - passive optical network that uses Ethernet technology and gigabit rates of data transfer
