Proudly  presented  by  Ovislink  Ov-2548F  is  an  enhanced  l2  switch,  which 

is  capable  of  high  performance  and  gigabit  speed  packet  forwarding.  This 

switch has 44 1000M SFP slots, plus 4 TX/SFP combo ports. due to its high 

performance  and  low  cost,  Ovislink  Ov-2548F  switch  is  considered  a  very 

competitive giga ethernet switching solution for community networking and 

workgroup networking in enterprise networks.

Application
 

Ovislink Ov-2548F provides gigabit ethernet speed at network access, enabling en-

hanced lan services for middle-level and large enterprise.

The Ovislink Ov-2548F also provides:

  • Intelligent features at the network edge, such as access control lists (ACLs) and  

     enhanced security.

   

  • Full fiber Gigabit Ethernet access.

   

  • Network control and bandwidth optimization using QoS, granular rate limiting,  

     acls, and IgMP and dhcP Snooping.

 

  • Network security through a wide range of authentication methods, and Network  

     access control based on users, ports, and Mac addresses.

 

  • Extended manageability using CLI.

 

  • Lifetime warranty.

 

  • Free software updates.
