Background
As optical transport networks carry ever-increasing volumes of data, security teams need ways to inspect live traffic without disrupting service. Traditional inline security appliances can become single points of failure, while passive monitoring requires flexible optical path management to connect audit devices on demand.
Optical routers — implemented with MEMS M×N matrix switches — enable security audit equipment to be dynamically connected to specific network links for scheduled or event-triggered inspection.
System Architecture
In this deployment, the optical router sits in the live fiber path and routes selected channels to network security audit devices. The audit system performs periodic scans to detect harmful activities including network Trojans, malware signatures, and anomalous traffic patterns. When inspection is complete, the optical path is restored to normal pass-through operation with minimal service impact.
Key Benefits
- Non-disruptive inspection — Optical switching enables audit devices to tap into live links on schedule without permanent inline insertion.
- Periodic threat scanning — Automated path switching supports routine scans for Trojans, viruses, and suspicious traffic patterns.
- Flexible routing — M×N matrix configurations route multiple links to shared audit equipment, improving resource utilization.
- High reliability — MEMS switches provide fast path restoration and stable optical performance during switching events.
- Scalable security infrastructure — Rack-mount matrix systems support growing port counts as network capacity expands.
Typical Deployment Scenarios
- Carrier backbone link security auditing
- Government and enterprise network compliance monitoring
- Data center interconnection (DCI) traffic inspection
- Scheduled deep-packet inspection via optical tap routing
