Professional Networked Audio Integration
Protect Critical SFP Ports from Tampering, Damage or Unauthorised Access
The Lindy SFP Port Blocker provides a fast, effective way to physically secure unused SFP (Small Form-factor Pluggable) network ports. These compact blockers are ideal for safeguarding fibre infrastructure in sensitive IT environments, AV-over-IP setups, and networked installations where access control is essential.
By preventing unauthorised connections, accidental cable insertions or foreign object intrusion, Lindy SFP Port Blockers reduce the risk of port damage and potential downtime. A robust insertion mechanism keeps each blocker firmly in place, with colour-coded keys ensuring only authorised removal. Additional keys and blocker packs are also available.
Physical Network Access Control
Blocks unauthorised SFP port use and deters accidental cable insertion
Fibre-Ready Protection

Visual Cue
Indicates unused ports or identifies disconnected endpoints
Low Cost, High Scalability
Ideal for large rollouts with minimal overhead
Latching Design
Mimics the clip action of real connectors – for a secure hold
Data Centres & Enterprise Network
Protect switchgear, routers and critical optical interfaces from disruption.
Education & Public Sector
Prevent tampering with fibre links in classrooms, libraries and shared facilities.
Retail & Hospitality AV Installations
Secure fibre-based AV equipment and signage systems in publicly accessible locations.
Facilities / Infrastructure
Visually mark inactive ports for future provisioning
Libraries / Shared Workspaces
Block unauthorised connections in public computing environments.
Healthcare & Labs
Protect equipment in clinical environments from unauthorised connections.
Lindy SFP Port Blockers deliver precise physical control over fibre ports, helping IT and AV professionals reduce risk and maintain infrastructure integrity. Easy to deploy, visually obvious and highly scalable, they’re the smart choice for any network where protection starts at the port.
