Laser Links for Primacom: The Jakarta Fiber Alternative That Changed the Equation

The Challenge

Greater Jakarta’s high-density zones are some of the hardest to wire: permits are complex, timelines are long, and deployment costs steep. How do you deliver enterprise-grade throughput in a city where you can’t dig?

Traditional fiber deployments faced permit and access bottlenecks, while microwave radio struggled in stability and scalability.

Primacom, one of Indonesia’s leading connectivity providers, needed a high-capacity, low-latency link in a restricted commercial area where fiber trenching was off the table and RF-based wireless fell short. The challenge was clear deliver fiber-class connectivity without the physical or deployment friction.

The Laser Leap

Transcelestial’s CENTAURI (a compact, wireless laser communications system) brought Primacom’s data center backbone online in record time.

CENTAURI transmits high-speed data through the air using laser light, bypassing ground infrastructure entirely. Within hours, Primacom established a short-range optical link delivering >99.99% uptime and seamless integration into their existing network.

At-a-Glance

Results that scale

Key takeaways

• Zero throttling: Full 10 Gbps sustained, even during peak rainfall.
• Low jitter and latency (< 50 µs): Uninterrupted service.. Round trip delay was <1ms

No truck rolls: Remote align & power adjustment meant zero on-site fixes. CENTAURI’s PAT (pointing tracking acquisition) compensated for any vibrations and sways seen during the weather conditions.
