Symmetric, Deterministic, Business-Class Transport
Fiber Internet provides Dedicated Internet Access (DIA) with symmetric bandwidth, low latency, and contracted Service Level Agreements (SLAs). Unlike best-effort broadband (coax/DSL), DIA is uncontended at the access, engineered for mission-critical apps, and built to pair with SD-WAN, cloud on-ramps, and security controls.
Where this fits: 🌐 Connectivity (Grammar) → Connectivity • 🖧 Networks & DCs → Networks & Data Centers • ☁️ Cloud (Syntax) → Cloud • 🔒 Security (Semantics) → Cybersecurity
🎯 Why Choose Fiber DIA (Outcomes You Can Prove)
- Symmetric throughput — the same upload/download (100 Mb/s → 1/2/5/10 Gb/s; higher on request).
- Low/steady latency — metro one-way typically ≤ 2–5 ms, with tight jitter for real-time apps.
- Contracted SLAs — availability, latency, jitter, packet loss, and Mean Time To Restore (MTTR).
- Routable options — static IPv4/IPv6, BGP peering, multi-homing. → BGP Management
- Scales cleanly — step-up speeds without architectural rework; native fit for SD-WAN/SASE. → SD-WAN • SASE
🧭 Service Profiles (Spelled Out & Compared)
1) DIA over Active Ethernet (Business-Class)
- Dedicated optical handoff, symmetric rates, strict SLAs, static routes.
- Best for branches, data centers, SaaS/API edges, and voice/video.
2) DIA over PON (XGS-PON/GPON) — Business PON
- Fiber to the premise via Passive Optical Network; XGS-PON supports 10 Gb/s tiers.
- Cost-effective where active Ethernet is unavailable; confirm SLA terms.
3) Broadband Fiber (Best-Effort FTTH/FTTP)
- Consumer-grade; oversubscribed access; variable SLAs (or none).
- Use as secondary underlay, not primary, for business-critical sites.

📐 SLO Guardrails (Recommended Targets)
| Metric | Metro Target (Class A) | Regional (Class B) | Notes |
|---|---|---|---|
| One-way Latency | ≤ 2–5 ms | 15–35 ms | By route class; publish 95th percentile |
| Jitter | ≤ 15% of latency | ≤ 15% | Voice/video stable when jitter is low |
| Packet Loss | < 0.1% sustained | < 0.1% | Watch for burst loss during peaks |
| Availability (DIA) | 99.95–99.99% | 99.9–99.95% | Depends on protection & diversity |
| MTTR | ≤ 4 hours | ≤ 4–8 hours | Tighten with dual-path designs |
We enforce SLOs via continuous synthetics and device telemetry; violations trigger the NOC. → NOC Services • Circuit Monitoring
🧱 Design Patterns (What “Good” Looks Like)
A) Resilient Branch (Primary + Diverse Backup)
- Primary: Fiber DIA (Active Eth or Business PON).
- Secondary: Fixed Wireless or LTE/5G for path diversity; optional third (satellite) for remote sites.
- Overlay: SD-WAN steers by loss/latency/jitter; sub-second failover.
→ Fixed Wireless • Mobile Connectivity • Satellite Internet • SD-WAN
B) Cloud-First Enterprise
- Fiber DIA to carrier-dense colo; private on-ramps to AWS/Azure/GCP for deterministic app paths.
- Policy: BGP with tagged “golden” routes to nearest on-ramp; Internet as tertiary.
→ Direct Connect • Colocation
C) Data-Center Edge (Low-Jitter North–South)
- Dual DIA + optional Wavelength for East–West data-center interconnect (DCI).
- BFD/ECMP and Anycast for resilient front doors; WAF/DDoS at perimeter.
→ Wavelength Services • WAF / Bot Management • DDoS Protection
🔐 Security Posture (Built-In, Layered)
- Edge controls: next-gen firewalls, TLS termination, Zero Trust user access. → Zero Trust
- Identity-first: SSO/MFA, admin boundaries, PAM for elevation. → IAM / SSO / MFA • PAM
- Segmentation: macro zones + microsegmentation at DC/cloud to stop lateral movement. → Microsegmentation
- Telemetry → SIEM/SOAR: DNS, netflow/IPFIX, firewall logs for detection & response. → SIEM / SOAR
🔗 Routing & Addressing (Options)
- Static IPv4/IPv6 allocations per site; PTR as needed.
- BGP peering for multi-homing across providers (hot-potato vs cold-potato by app).
- Anycast for global services (DNS/web/API) with health-based withdraw.
→ BGP Management
🔄 Diversity That Actually Works
- Laterals & building entries: separate conduits to reduce shared-cut risk.
- POP/route diversity: require provider diversity letters; distinct bridges/manholes.
- Carrier diversity: primary/secondary ISPs, ideally on different last-mile plant.
- Media diversity: combine fiber with fixed wireless or LTE/5G.
→ Circuit Monitoring • Fixed Wireless
🧰 Turn-Up & Operations (No Surprises)
- Pre-qualify addresses; confirm build/outside-plant and feasible Ready For Service (RFS) date.
- Order & LOA/CFA (if colo); schedule site survey and install window.
- Handoff type — optical (SMF, LR/LR4) or electrical; confirm SFP/SFP+ specs.
- Provision IPs (v4/v6), static or BGP; apply security baseline.
- Test — RFC 2544 / ITU-T Y.1564 baselines; document latency/jitter/loss.
- Monitor — add to NOC dashboards; set alarms & SLOs; open carrier tickets on breach.
