Understanding Sparklight Modem Requirements
A modem compatible with Sparklight must meet specific criteria. DOCSIS 3.1 is mandatory for Gig plans, offering speeds up to 2.5 Gbps and backward compatibility with DOCSIS 3.0 for lower tiers (<300 Mbps). Sparklight prohibits DSL modems and second-hand units to ensure reliability. For phone service, customers must lease an ARRIS eMTA for VoIP compatibility. Modems need 32×8 channel bonding for high download/upload speeds and multi-gig Ethernet ports for future-proofing. Always verify compatibility on Sparklight’s approved modem list.
