Fast Ethernet 48+4G combo ports, managed switch, rack 19"
Edge-Core's ES3552M is one of best choices for high density Ethernet port switch at a very reasonable cost.
The ES3552M is a 48 port 10/100 copper switch with 4 SFP and copper Gigabit Ethernet combo ports for uplink and fiber optic connections. All copper ports support auto-negotiation of speed and detection of straight/crossover cable connections through the auto MDI/MDIX capability.
Besides the priority control support, an FTTx project needs also VLAN capabilities. Sometimes VLAN is used to segregate different services to same customer, but most often, VLAN networks are useful in sharing a same fiber optic link to several customers which are in proximity of each other and under the standard copper cable coverage(MDU - appartments or condominiums, MHU and business centers do qualify under these particular FTTB deployments). The ES3552M switch supports port based VLAN, IEEE 802.1q VLAN and Q-in-Q VLAN tagging, rapid spanning tree and IGMP snooping. Its backplane switching capacity is 17.6Gbps.
Probably one of the most important features of ES3552M are its impressive QoS capabilities like: bandwidth control per port ingress and egress, 802.1p class of service, WRR and Strict Priority functions and Storm Control.
The ES3552M offers also strong management support like: local console for CLI or Telnet, web interface and SNMP management. Multiple switch configurations can be stored and remote firmware upgrade keeps also previous version safe and ready to restore in case of failure.
