Problem addressed
Distributed sites can have unclear fiber paths and device counts, different optical interfaces and fiber combinations, or an unverified requirement for redundancy. Establish the connections before finalizing the configuration.
Solution benefits
- Connect distributed points along a route
Match Ethernet interfaces and traffic at each road or perimeter CCTV point. - Aggregate along the fiber path
Relate each device to adjacent fiber segments and a clear central connection. - Match interfaces as required
Choose fixed optical ports or SFPs according to fiber and connector conditions. - Evaluate redundancy conditionally
Assess a closed ring only after protocol, interoperability and node requirements are confirmed.
Suitable applications
- Multiple IP CCTV points along a road.
- Distributed terminals on a campus perimeter or across site areas.
- Sites with verifiable fiber routes, power and aggregation locations.
Connection overview
CCTV device → local fiber access unit → successive fiber-connected sites → aggregation / control center.
Optional closed ring: only after confirming the protocol, interoperability and node conditions.
The main arrangement is a daisy chain. Close a ring only where the protocol, devices on the same network and node conditions have been confirmed. The series name alone does not establish a common recovery or switchover specification.
Equipment selection
Models and optional equipment must be matched to the actual site. These items do not form a fixed kit.
| Equipment | Role and selection conditions |
|---|---|
| Fiber daisy-chain transmission unit AEO-8814D/POE, AEO-8S3408-M | Select for device interfaces, optical ports, PoE and management needs. Check the functions of each exact model. |
| SFP module | Use only where the main equipment has a matching SFP port. Check speed, wavelengths and compatibility. |
| Fiber accessories | Match fiber cores, joints, connectors and maintenance locations. |
| Multifunction digital transmission cabinet | Optional for outdoor mounting, power distribution or status acquisition. Confirm space and loads. |
Information needed for selection
Provide site distribution, interfaces, bitrates, details for each fiber segment and power. Select link speeds using actual traffic and the capabilities of every port. Check per-port PoE limits and the total budget separately.
