Key Takeaways
- DOCSIS 3.1 certified modem capable of up to 3.6 Gbps downstream and 1.5 Gbps upstream speeds
- Backward compatible with DOCSIS 3.0 networks using 32x8 channel bonding
- Compatible with Spectrum, Mediacom, and select other cable providers
Technicolor TC4400 Product Details
The Technicolor TC4400 is a DOCSIS 3.1 cable modem built for multi-gigabit internet plans. It supports downstream speeds up to 3.6 Gbps and upstream speeds up to 1.5 Gbps, making it a strong choice for heavy bandwidth usage including online gaming, 4K streaming, and large file transfers.
DOCSIS 3.1 Certified with CableLabs
The TC4400 is fully compliant with DOCSIS 3.1 specifications and uses 2 Orthogonal Frequency-Division Multiplexing (OFDM) downstream channels to achieve up to 4 Gbps downstream and 1 Gbps upstream. It is also backward compatible with DOCSIS 3.0 networks, where it operates with 32 bonded downstream and 8 bonded upstream channels.
Easy to Install and Manage
Front-panel LEDs provide clear indication of startup sequence, operational status, and connectivity. The TC4400 also includes a web-based user interface for managing network settings, security options, and parental controls.
Future-Proof High-Bandwidth Technology
Because the TC4400 supports both DOCSIS 3.0 and 3.1, it works on current cable networks and is ready for provider upgrades to multi-gigabit DOCSIS 3.1 service. Investing in a DOCSIS 3.1 modem now means you are unlikely to need a modem replacement for several years.
Additional Features
- DOCSIS 3.1 compliant, backward compatible with all previous DOCSIS versions
- 2x2 OFDM(A) bonded channels in DOCSIS 3.1 mode
- 32x8 bonded channels in DOCSIS 3.0 mode
- Switchable diplexer with upstream frequency up to 204 MHz split
- 1.2 GHz full-band capture tuner
- Built-in RF spectrum analyzer
- 2 Gigabit Ethernet LAN ports
- Supports IPv4, IPv6, and DS-Lite
- Designed to meet current ECO energy conservation standards
What's Included
- Technicolor TC4400 DOCSIS 3.1 Modem
- Ethernet cable
- Power supply cable
- Installation instructions (available online)
Technicolor TC4400 Compatibility
The Technicolor TC4400 is compatible with Mediacom, Spectrum (formerly Charter/Time Warner Cable), and select other cable providers. Always contact your internet service provider before purchasing to confirm that the TC4400 is approved for your specific plan and area. Some plan speeds may not be supported.
