Application Scenarios
Large-Scale Mixed PON Access for Urban & Suburban Networks (Asia)
A leading telecom operator in India deployed CSHD interface boards with MA5800-X15 OLTs to upgrade its mixed GPON/EPON network across Mumbai and Delhi, covering 400,000 households and 30,000 SMEs. Each CSHD’s 16 dual-mode ports connected to both GPON and EPON ONTs, delivering stable 2.5Gbps downlink for 4K streaming and 1Gbps uplink for remote work. The dynamic routing function optimized traffic to core networks, while VLAN isolated residential and enterprise traffic. With 120 CSHD boards deployed, the operator achieved 480Gbps total access capacity, reducing OLT slot usage by 50% vs. single-protocol boards—seamlessly integrating existing EPON infrastructure with new GPON expansions.
