  • IEEE 802.1x security function, and VLAN assignment


GSW-4448CM is an SNMP manageable Gigabit Ethernet switch for FTTx deployment or Gigabit Ethernet fibre aggregation that is equipped with 48 1000Base-X CSFP ports included 4 Gigabit combo ports (RJ45 or CSFP slot) and 4 1G/10Gbps dual rate SFP+ slots.  The GSW-4448CM supports a special BX optics (Compact SFP) which can double the fibre port density to 48 links, make it be attractive  for the FTTx deployment and scenarios where increased user links are required in limited construction space. With advanced layer 2 and QoS features, this switch is targeted at multi-service operators (MSO) with a desire to deploy provisioned triple play services via active Ethernet FTTx network infrastructures.

Managed Ethernet switch


Fibre based network infrastructures offer the data rates required by triple play services such as high speed internet access, VoIP and HD IPTV. The GSW-4448CM Ethernet access switch provides VLAN, QoS and IGMP L2 feature sets as well as robust security management to facilitate service provider's build out of a manageable and secure FTTx access network.
