Introduction
Fiber Internet—also known as Dedicated Internet Access (DIA)—delivers guaranteed, symmetrical connectivity over optical fiber. It is the gold standard for enterprise and carrier-grade networks.
Fiber is almost always delivered with an Ethernet handoff (RJ-45 copper or SFP optical module) to customer equipment, which means Fiber Internet and Ethernet Services go hand-in-hand.
SolveForce integrates Fiber DIA with Ethernet transport services to provide:
- Nationwide and global reach
- Symmetrical speeds up to 1 Tbps and beyond
- SLA-backed performance (uptime, latency, jitter)
- Low-cost aggregation with SolveForce’s best-price guarantee
I. Fiber Deployment Models
- 🏠 FTTH (Fiber to the Home)
Fiber to residences, delivering gigabit+ broadband. - 🏢 FTTB (Fiber to the Building)
Fiber terminated inside office buildings, often Ethernet to the suite. - 🏬 FTTP (Fiber to the Premises)
Umbrella term covering both FTTH and FTTB. - 🚏 FTTC (Fiber to the Curb)
Fiber to a nearby street cabinet, then coax or copper to the end-user. - 🖧 FTTN (Fiber to the Node/Neighborhood)
Shared neighborhood node, typically with copper last-mile. - 🏭 FTTZ (Fiber to the Zone)
Industrial or municipal deployments serving campuses or metro grids. - 🏢 FTTO (Fiber to the Office)
Direct fiber connections to each desk or workstation in large enterprises.
II. Fiber + Ethernet Service Delivery
Ethernet over Fiber (EoF)
The dominant handoff for business fiber is Ethernet, provided as:
- Fast Ethernet (100 Mbps)
- Gigabit Ethernet (1 Gbps)
- 10/40/100 Gigabit Ethernet
- Carrier Ethernet (CE 2.0) standardized by MEF for enterprise WANs.
Ethernet Transport vs. Ethernet LAN
- Ethernet Transport Service (ETS): Point-to-Point, Point-to-Multipoint, and Any-to-Any over fiber backbones.
- Ethernet LAN/Ethernet Private Line: Extends LAN across metro or wide-area fiber networks.
Ethernet Handoffs
- Electrical (Copper): RJ-45 for 10/100/1000BASE-T up to 100m.
- Optical (Fiber): SFP/SFP+/QSFP for 1/10/40/100/400G handoffs to routers/firewalls.
III. Hardware & CPE (Customer Premises Equipment)
- Routers: Cisco, Juniper, Fortinet, Ubiquiti, capable of BGP/OSPF/MPLS peering.
- Firewalls: Next-Generation Firewalls (NGFW) for perimeter protection.
- Switches: Layer-2/3 with VLANs, QoS, and PoE as required.
- ONT (Optical Network Terminal): Converts optical signals to Ethernet.
- OLT (Optical Line Terminal): Provider aggregation equipment for multiple ONTs.
IV. Fiber & Ethernet Speed Tiers
Fiber DIA and Ethernet transport scale seamlessly, from SMB to hyperscale.
| Tier | Symmetrical Speed | Use Case |
|---|---|---|
| Fast Ethernet | 100 Mbps | SOHO, small branches, basic apps |
| Metro Ethernet | 300–500 Mbps | Growing SMBs, cloud, VoIP, HD conferencing |
| Gigabit Ethernet | 1 Gbps (1000 Mbps) | Standard enterprise, UCaaS, healthcare |
| Multi-Gigabit | 2–5 Gbps | CAD, video production, SaaS scale-ups |
| 10 Gigabit Ethernet | 10 Gbps | Data centers, HPC, financial trading |
| 40 Gigabit Ethernet | 40 Gbps | Research, hyperscale interconnects |
| 100 Gigabit Ethernet | 100 Gbps | Carrier backbones, cloud interconnects |
| 400 Gigabit Ethernet | 400 Gbps | Hyperscale fabrics, metro aggregation |
| 800 Gigabit Ethernet | 800 Gbps | Carrier core, future-ready PoPs |
| 1 Terabit Ethernet | 1 Tbps (1,000,000 Mbps) | IEEE roadmap standard; AI/ML clusters, global Tier-1 ISPs |
V. Advantages of Fiber + Ethernet
- Dedicated Bandwidth: Unlike coax/DSL, no shared neighborhood congestion.
- Symmetry: Upload = Download speeds, essential for cloud and collaboration.
- Scalability: Easily upgrade from 100 Mbps to 1 Tbps as business grows.
- Reliability: SLA-backed with uptime guarantees (99.9%–99.999%).
- Interoperability: Ethernet handoffs integrate directly with routers, firewalls, and switches.
VI. Use Cases
