StarTech.com SFPCAP10 SFP and SFP+ Dust Covers 10-Pack Santoprene TPE Plugs with Pull Tab for Empty Switch Ports Black
SFP / SFP+ Dust Covers for Empty Switch Ports — 10-Pack
The StarTech.com SFPCAP10 is a pack of ten black dust covers that plug into empty SFP and SFP+ cages on switches, routers, firewalls and network cards. Made of Santoprene thermoplastic rubber (TPE), each cover seals the open port against dust and debris and has a pull tab, so you can remove it quickly when you install a transceiver. An open cage collects dust that can later end up on the transceiver contacts or the optics. In practice you fit them to every unused fibre port after installation or during a rack clean-up, and keep the spares for ports you free up later.
