This solution is suitable for the application of broadband users in dense areas such as new cell broadband access or old cell upgrade. A large-capacity ISCOM5800 or small-capacity ISCOM5504 OLT equipment is placed in the local server room, and the backbone fiber to the cell is then distributed to the user's building through indoor or outdoor type optical splitters, and the end user is directly connected through the ONU (ISCOM51xx, ISCOM52xx, ISCOM53xx) placed in the building handover box, or for retaining the original The switch provides multiple Ethernet access by means of an ONU downlink switch. The solution can provide users with pure data services and "data + voice" services by selecting different types of ONUs, as well as eventually realising "triple play" applications.

Gigabit high-speed bandwidth to ensure user bandwidth and service quality, and good scalability for smooth network bandwidth upgrade Multi-service access, providing users with optional combinations of data, voice and video (VOD, IPTV, CATV) services Flat network structure not only reduces network hierarchy, but also optimises network performance Flexible configuration of minimum, guaranteed and peak bandwidth, fast and flexible bandwidth scheduling by DBA algorithm, and perfect QoS mechanism, greatly improving user perception and satisfaction End-to-end management, backbone fibre savings, no need for cell rooms and active equipment, lower construction management and maintenance costs
