Features:

✓Economic and Flexible: The modem provides operators with an economic option for providing Ultra-Broadband services, with four times the current maximum user data throughput, approximating 160 Mbps in DOCSIS mode and 195 Mbps in EuroDOCSIS mode, without the need for hybrid fiber coax (HFC) plant upgrade. 

✓Enhanced Network Management: With the ability to provision and manage IP multicast, GigE (RJ-45) data port with Auto Negotiate and Auto MDIX, and user-friendly online diagnostics--the SB6121 has got the features to give you full-control over network management and maintenance. 

✓Backward Compatibility: Backward compatible to DOCSIS 1.0, 1.1 and 2.0, the SB6121 also supports both IPv4 and IPv6, Advanced Encryption Services, and all other DOCSIS 3.0 standards. 

✓Low Pass Filter: Internal Low Pass Filter to eliminate MoCA signal overload. 

✓DOCSIS 3.0 Certified: Channel bonding of up to four downstream channels and four upstream channels increasing data rates of well over 100 Mbps in each direction.
