The Edgecore ECS4530-54CSFP switch is a high port density Gigabit Ethernet ﬁber switch with four 10G uplink ports. By inserting a CSFP transceiver with two bidirectional ﬁber ports into a CSFP port, Internet Service Providers (ISPs) and Multiple System Operators (MSOs) can support twice as many subscribers per port and reduce the space and heating or cooling costs needed for deploying two 24 port switches and larger 48-port switches. The switch is ideal for ISPs/MSOs that want to provide home users with FTTH triple-play services with up to a Gigabit of bandwidth. It is also ideal for ISPs/MSOs that want to aggregate FE/GE access switches with Gigabit ﬁber uplinks. The ECS4530-54CSFP switch is packed with features that bring high availability, comprehensive security, robust multicast control, and advance QoS to the network edge, while maintaining simple management. The switch also supports the most advanced IPv6 management, IPv6 security, and IPv6 multicast control in accordance with the growth of IPv6 deployment.
