AINOPOL Optical-Electrical Convergence Solution: One Single Fiber for All Classroom, Surveillance and Broadcasting Needs

On the first day of September, sunlight streams into the newly-built comprehensive building.

This is the landmark building of XX Middle School, constructed over two years. It has six floors, forty classrooms, eight functional rooms, and a lecture hall that can hold 500 people. One week before the new semester, all devices were installed one after another: smart blackboards, teaching large screens, surveillance cameras, wireless APs, IP broadcast speakers, etc.

Installation technicians were busy at work, yet Director Chen from the IT Center frowned deeply — how to lay out the network?

Under the traditional solution, this building would require:

One weak current shaft per floor with a switch

Two network cables per classroom (teaching network + surveillance network)

Additional network cables in corridors for wireless APs and broadcasting

All lines converged to a first-floor cabinet, then connected back to the central equipment room via optical fiber

In total, over ten thousand meters of network cables, more than a dozen switches, and fully packed weak current shafts. Once installation was completed, the shafts would turn into a “cable spider web”, making future maintenance and expansion a nightmare.

Worse still, all those switches had to run 24/7. In summer, the temperature in weak current shafts could reach 50°C, requiring air conditioning for cooling — soaring electricity bills and high failure rates.

Was there a solution to free the new building from “cable webs” and “high-temperature furnaces”?

Yes. The AINOPOL Optical-Electrical Convergence Solution was designed precisely for such scenarios.

Based on PON passive optical network technology, AINOPOL’s solution solves all problems with one single fiber:

Central Equipment Room: One OLT Manages the Entire Building

An OLT device is deployed in the central equipment room, replacing over a dozen switches in the traditional scheme. All signals originate here and reach every corner of the new building through one backbone optical fiber.

Weak Current Room: Optical Splitter Box Instead of Half-Height Cabinets

An optical splitter box is installed in the weak current shaft on each floor. The optical signal is split into multiple paths and distributed to each classroom.

One ONU for All Services

One ONU terminal is deployed in each classroom. This compact device simultaneously provides:

Wired ports: for smart blackboards and teaching computers

Wireless Wi-Fi: full classroom coverage for student tablets and teachers’ mobile devices

Surveillance interface: connects to classroom cameras for real-time video transmission

Broadcast interface: connects to IP speakers for campus broadcasting and emergency announcements

One optical fiber into the classroom supports all services. Network cables only run from the ONU to devices, with a maximum length of 3 meters, keeping the entire classroom neat and tidy.

The weak current rooms, once Director Chen’s biggest headache, were completely transformed:

Traditional solution:1.2-meter-high cabinet on each floor, stuffed with switches and fiber transceivers and dense cables. Air conditioning was mandatory in summer, with loud noise and high electricity costs.

New solution:Only a palm-sized optical splitter box mounted on the wall — passive, silent, and heat-free. No cabinet, no air conditioning, not even a locked door, as there is no valuable equipment inside.

Network equipment for the entire building was reduced from over a dozen switches to one central OLT and dozens of classroom ONUs. The number of active devices dropped sharply, cutting overall energy consumption by more than 30%.

Director Chen calculated: the building would save nearly 10,000 yuan annually on air conditioning alone, totaling 100,000 yuan over ten years.

Even more satisfying was the solution’s scalability.

After the semester began, the school suddenly needed to add a dance studio on the sixth floor with network access. Under the traditional scheme, new network cables would have to be pulled from the weak current shaft, requiring wall drilling and taking at least half a day.

Now? Simply install an ONU in the dance studio and connect the fiber from the nearest splitter box — spare ports are pre-reserved, ready for plug-and-play. The whole process takes 30 minutes, with no wall drilling or disruption to classes.

For higher bandwidth demands, such as future 8K video teaching, only the ONU needs to be replaced while the optical fiber remains in place. Fiber supports 10G, 50G and beyond, with one deployment serving up to 20 years.

Fiber transmission ensures inherent stability:

Immunity to electromagnetic interference: fluorescent lights and high-power speakers in classrooms do not affect network speed

Long transmission distance: full signal strength from the central equipment room to the farthest sixth-floor classroom

Service life of up to 25 years: one deployment lasts until the next major school renovation

Smooth surveillance video, low-latency teaching live streams, and clear broadcast audio — stability is the foundation of all smart applications.

With no air conditioning needed in weak current rooms, network failure rates plummeted, and teachers no longer complained about slow internet in the afternoon.

On the first day of school, Director Chen entered the weak current room of the new comprehensive building. Only a small splitter box hung quietly on the wall, with several optical fibers neatly connected. No buzzing fans, no overheated cabinets, no tangled network cables.

He walked to a sixth-floor classroom, turned on the smart blackboard, and played a 4K teaching video — clear and smooth. Corridor surveillance fed back real-time footage, and the broadcast system stood by.

Teachers commented: “The network in the new building is incredibly fast and never lags.”The principal praised: “Excellent network planning, worry-free for the next decade.”

Director Chen smiled to himself: It wasn’t my skill — it was choosing the right solution.
