Camera access to aggregation
CCTV & Security Fibre Networks
Surveillance fibre design must preserve bandwidth, distance and recovery across camera zones, access switches, control rooms and perimeter routes.
Direction must be controlled
Measured route budget required
Camera count alone does not define the uplink. Resolution, frame rate, codec, recording mode, burst behaviour and future camera growth determine the bandwidth and redundancy requirement.
Outdoor cabinets and long perimeter routes add temperature, power, connector-cleanliness and restoration constraints. Fibre scarcity may justify BiDi, but each TX/RX pair must be controlled at both ends.
The optical BOM should identify switch model, port, route, fibre core, camera zone and spare location so a field replacement restores the correct path.
Translate the network requirement into an optical path
Size the traffic, route and failure consequence for each surveillance zone.
| Network requirement | Recommended design path | Confirm before approval |
|---|---|---|
| Local camera access | 1G LX or copper-to-fibre path for modest zone aggregation. | Switch SFP support, fibre and PoE design boundary. |
| High-density aggregation | 10G LR uplink sized from actual video traffic and growth margin. | Codec load, oversubscription, storage traffic and redundancy. |
| Single-fibre route | Matched 10G BiDi pair where fibre cores are constrained. | TX/RX direction, pair identity and host support. |
| Long perimeter link | 1G EX or engineered 10G ER after route-budget review. | Loss, splices, cabinet environment and restoration access. |
Product examples for a controlled starting point
These products anchor local, aggregated, single-fibre and long-perimeter CCTV paths.
Catalogue examples define a starting configuration, not automatic proof for a different host, revision, reach or fibre plant.
Where this application architecture is used
Separate camera-zone availability from core recording and command-centre availability.
Campus surveillance
Multiple buildings feed a central recording and monitoring room.
Perimeter and gate security
Long outdoor routes require cabinet and restoration planning.
City or transport cameras
Distributed access switches aggregate over controlled fibre uplinks.
Critical-site redundancy
Diverse paths and mapped spares protect recording continuity.
Sample, compatibility and release workflow
Validate traffic, host compatibility and field restoration as one CCTV acceptance path.
- 1
Calculate zone traffic
Use resolution, codec, frame rate, retention traffic and growth.
- 2
Map every uplink
Record switch, port, route, fibre core, distance and connector.
- 3
Validate the named switch
Check recognition, DOM, errors and sustained representative traffic.
- 4
Control BiDi and outdoor identity
Pair wavelengths and separate industrial-temperature lines.
- 5
Test the restoration record
Confirm labelled spare, location and swap procedure.
MOQ, lead time and pricing factors
Distributed sites, outdoor conditions and field spares often affect total cost more than the SFP unit price.
| Commercial item | What changes the outcome | Buyer action |
|---|---|---|
| MOQ | Many small zones and host codes can fragment quantities. | Group by exact identity and route class. |
| Lead time | Outdoor and BiDi lines may require separate validation and pairing. | Provide zone priorities and installation date. |
| Price | Reach, temperature, BiDi pairing and warranty affect cost. | Compare complete route lines, not isolated modules. |
| Spares | Distributed cabinets need mapped replacement stock. | Define spare site, label and replenishment rule. |

Failure modes to remove before shipment
Under-sized uplink
Average traffic can hide recording bursts and future camera growth.
Reversed BiDi pair
Incorrect TX/RX direction prevents the link despite correct form factor.
Outdoor grade assumption
Weather data does not equal internal cabinet temperature.
Unlabelled field spare
Technicians can install the correct-looking module on the wrong route.
Application-specific questions
How much bandwidth does a CCTV uplink need?
Calculate from codec, resolution, frame rate, stream count, recording pattern, overhead, burst and growth margin.
When should BiDi be used?
When fibre cores are constrained and the host supports a controlled TX/RX wavelength pair.
Do outdoor cabinets always need industrial optics?
Use measured internal conditions; outdoor location alone is not enough to select or reject a temperature grade.
What should the security RFQ include?
Camera/zone count, traffic estimate, switch models, routes, fibre cores, distance, cabinet conditions, redundancy, quantity and spare locations.
