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.
