A Smart City PON+CCTV solution converges two traditionally separate networks - fiber broadband access and video surveillance - onto one passive optical network. Instead of building a dedicated network for cameras, operators deploy a single optical distribution network (ODN) that serves both.
This matters because municipal and campus surveillance projects have historically required duplicated infrastructure: separate fiber runs, separate power feeds, separate switching equipment, and separate maintenance contracts. A converged PON eliminates that duplication at the physical layer.
The concept sits at the intersection of two established technologies:
FTTH/PON access (
GPON,
XGS-PON,
10G EPON) and
IP video surveillance (PoE cameras). SOFTEL has manufactured equipment for both sides of that intersection for 20 years.
One network, two services - the same ODN carries FTTH broadband and CCTV video traffic
PoE ONU replaces three devices - fiber converter + PoE switch + power supply become one box
No AC power at the pole - PoE carries power over the Ethernet cable to the cameras
SOFTEL PONT-4GE-PSE-H - industrial-grade PoE ONU with 6 kV lightning protection and -40°C to +70°C operating range
Full chain from one factory - OLT, PoE ONU, fiber cables, and passive ODN components
Safe City & Municipal Surveillance
Pole-mounted
PoE ONUs connect clusters of IP cameras to the city's PON backbone, sharing fiber with public broadband services.
Industrial Parks & Campuses
Perimeter and internal surveillance share the same fiber plant as office and residential connectivity.
Highway & Tunnel Monitoring
Long-reach PON (up to 20 km) with industrial-temperature ONUs suited to harsh environments.
Smart Pole Integration
Camera, WiFi, and lighting combined on a single pole, all fed from one fiber drop.
How Does the PON+CCTV Architecture Work?
| Tier |
Device |
Function |
| Central Office |
OLT |
Aggregates PON traffic; supports GPON / XGS-PON / 10G EPON |
| Edge / Camera Site |
PoE ONU |
Terminates fiber, converts to Ethernet, injects PoE power |
| Endpoint |
IP Cameras |
Receive data + power over Ethernet from the ONU |
Data flow: Cameras send video streams upstream to the PoE ONU over Ethernet → the ONU converts the signal to optical and transmits over the PON → the OLT aggregates traffic at the central office.
Power flow: DC power enters the
PoE ONU (typically 48V), which injects it onto the Ethernet cable to power the cameras - removing the need for local AC power at each camera pole.
The
PONT-4GE-PSE-H is an industrial-grade
XPON ONU purpose-built for outdoor surveillance and harsh-environment deployments.

What is a PoE ONU?A PoE ONU (Power over Ethernet Optical Network Unit) is an ONU that terminates a PON fiber connection and provides PoE output on its Ethernet ports. It delivers both data and electrical power to connected devices such as IP cameras, removing the need for separate power cabling.
How many IP cameras can one PoE ONU support?The SOFTEL PONT-4GE-PSE-H provides four Gigabit PoE ports, so it can directly support up to four IP cameras. Larger clusters are handled by adding additional ONUs on the same PON splitter.
Does PoE ONU require AC power at the camera pole?No. Power is supplied to the PoE ONU at the point where mains power is available, and the ONU injects power onto the Ethernet cable to the cameras. This eliminates the need for local AC feeds at each camera location.
Can the same fiber carry broadband and CCTV traffic?Yes. PON is a point-to-multipoint architecture, and the ODN can carry both FTTH broadband and surveillance video simultaneously. VLAN and QoS settings keep the two traffic types logically separated and prioritized.
What is the maximum distance between the OLT and the PoE ONU?The PONT-4GE-PSE-H supports transmission distances of 0–20 km, depending on the PON budget and splitter configuration.
Is the PoE ONU suitable for outdoor installation?Yes. The PONT-4GE-PSE-H is industrial-grade, with a metal housing, 6 kV lightning protection, and an operating temperature range of -40°C to +70°C, making it suitable for pole-mounted outdoor deployment.
Which OLTs is the PoE ONU compatible with?The PONT-4GE-PSE-H supports docking compatibility with OLTs from multiple vendors, and auto-senses whether the peer OLT is running GPON or EPON.
What is the power consumption of the PoE ONU?Less than 72 W, including the PoE power delivered to connected cameras.
