Optimum Business —
100% Fiber, Ethernet & Hosted Voice

Optimum Business operates a 100% fiber-optic infrastructure spanning 16 states, with more than 23,000 fiber route miles, 230,000 broadband miles, and 33,000 fiber-to-the-premises miles. Coverage is strongest across the Northeast and West, including major metros like New York, Connecticut, New Jersey, and broad portions of California and the Mountain West. For multi-site businesses with locations outside the Optimum footprint, Fibi pairs Optimum where it's available with other carriers elsewhere — so a single sourcing engagement covers all your sites without forcing every location onto the same provider.

There are three main connectivity tiers. Secure Internet (300 Mbps, 500 Mbps, or 1 Gbps) bundles broadband with built-in cybersecurity protection — appropriate for small offices and retail sites. Business Fiber Internet runs from 300 Mbps to 8 Gbps over fiber-to-the-premises, with symmetrical upload and download speeds. Fiber Dedicated Internet Access (DIA) goes up to 10 Gbps with a formal SLA, BGP peering on request, and IPv4/IPv6 allocation — the right tier for headquarters, data centers, and locations that depend on guaranteed performance. Bandwidth upgrades on the fiber network are typically a software change with little or no downtime.

Optimum Business has a full enterprise portfolio beyond Internet access. Layer 2 Ethernet services include E-Line for point-to-point site connectivity (up to 10 Gbps) and E-LAN for any-to-any multipoint connectivity, both available with optional optical handoffs. Wave services provide dedicated optical capacity for high-volume inter-site transport. Voice services span Business Hosted Voice (cloud PBX), SIP and PRI trunking, single-seat hosted voice, and toll-free. Enterprise Cloud Connect provides private connectivity to multiple cloud providers via Equinix Cloud Exchange. Managed services include 24/7 Proactive Monitoring with 15-minute outage notifications, Managed DDoS Protection, Pro WiFi, and Bus WiFi for fleet operators.

Reliability comes from the underlying fiber-to-the-premises architecture combined with Optimum's Proactive Monitoring service, which provides circuit-level device health monitoring and alarm analysis at both ends of the transport network. When a fault is detected, you receive notification within 15 minutes — often before end users notice — and the support team handles fault isolation, remote repair, and ticket-lifecycle management with escalation as needed. For businesses on Business Fiber, fiber redundancy and the ability to scale bandwidth via software upgrade reduce the operational footprint compared to copper-based alternatives.

Optimum Business is a strong fit for organizations with locations across the Northeast or West Coast, retail and restaurant chains, multi-tenant office buildings, education institutions, and fleet operators (Bus WiFi). The 100% fiber network is particularly competitive on symmetrical bandwidth and on hosted voice bundling. It is less competitive in markets entirely outside the 16-state footprint or for single-site customers needing a global SD-WAN integrated by a Tier-1 IP backbone provider. Fibi's role is to compare Optimum side-by-side with national alternatives — Lumen, Verizon, AT&T, Spectrum, Frontier — so you choose the right carrier per site rather than defaulting to one nationwide.

No. Your contract is signed directly with Optimum Business — Fibi is not a party to the agreement. Pricing follows Optimum's published rates, and in most cases Fibi can negotiate equal or better terms by sourcing competitive quotes from other regional and national carriers in parallel. Fibi's advisory work is funded by Optimum at no additional cost to your business, so engaging Fibi adds the comparison, multi-vendor sourcing, and ongoing escalation layer without affecting your invoice line items or contract terms.
