Fiber Internet Providers in Pittsburgh
### 1. AT&T Fiber
AT&T Fiber is expanding in Pittsburgh, bringing symmetrical gigabit service to neighborhoods and suburbs throughout the metro. Where available, it outperforms cable on every metric.
**Speeds:** 300 Mbps -- 2 Gbps (symmetrical) **Starting price:** ~$55/mo **Type:** Fiber optic (FTTH) **No data caps. No equipment rental fees.**
Why Choose Fiber?
Fiber internet delivers advantages that cable simply cannot match:
- **Symmetrical speeds** -- your upload speed equals your download speed, critical for video calls, cloud backups, and the tech/healthcare remote work common in Pittsburgh - **No shared bandwidth** -- unlike cable, your fiber connection is dedicated and does not slow down during peak hours - **Better for AI, cloud, and video** -- low latency and consistent throughput make fiber ideal for remote work, telehealth, and smart home devices - **No equipment rental fees** -- AT&T Fiber includes the gateway at no extra charge - **No data caps** -- AT&T Fiber has no data caps, while [Xfinity](/providers/xfinity) imposes a 1.2 TB monthly limit
Fiber vs Cable in Pittsburgh
Pittsburgh has been dominated by Xfinity cable, but AT&T Fiber's expansion is providing genuine competition. Where fiber is available, it delivers dramatically better upload speeds: 1 Gbps symmetrical versus Xfinity's ~35 Mbps upload. Xfinity also imposes a 1.2 TB data cap and charges equipment rental fees.
Pittsburgh's hilly terrain means fiber deployment follows valley corridors first, with hilltop neighborhoods sometimes waiting longer. If fiber is not yet available at your address, check back periodically -- coverage is expanding.
