SFP SFP+ Dust Cover, Anti-Dust Cap for SFP SFP+ port, Fiber Optic Dust Caps, Port Protector for Switch/Network Cards/Router/Media Converters, PVC, 50 Pack

This works perfectly for QSFP ports. I do with it was a little softer silicoln rather than PVC. Although, QSFP ports don't have parts to damage near the outer connector so, not a big deal.

Dust covers work great to keep dust and other particles out of the ports.

Not all the QSFP (QSFP28) ports get used on our ethernet switches. We wanted to keep dust out of the extra ports. The product site unfortunately uses the same SFP port cover dimensions but these *will* fit the 6x18mm size of the QSFP ports.

Excellent quality. No smudging. Soft, but firm rubber. Fit RJ-45 ports snugly. I have these installed in switches in a vertical orientation. They are excellent for their primary intended purpose - keeping dust out of your equipment ports - and they also work well even upside down (they don't fall out).

I bought these to cover the SFP+ ports of my devices. I have used it in multiple Mikrotik devices and a Juniper switch. Works like a charm.

It was easy to get a hard-to-find product with this company. Dust covers for RF45 ports were lost in the assembly process and the end customer had to have them. Problem solved with these high quality, easy to handle dust covers.

These are my new favorite rj45 protectors they are fantastic quality.

It just works and does exactly what it’s expected to do

Bonne qualité bouchon usb

Ich habe die Abdeckungen bestellt, um meine ungenutzten Ports in meinen Netzwerkgeräten abzudecken. Die Caps sitzen sehr gut und fallen nicht raus, auch wenn man das Gerät mal über Kopf hält. Dementsprechend braucht man auch etwas Kraft um die Caps zu entfernen. Sie sind sehr sauber verarbeitet und erfüllen ihren Zweck

Excellent quality fit great in my switch stop the dust getting in very happy

Je conseille cet article pour préserver les entrés de la poussière par les ports réseaux de votre pc.

Flotte Lieferung und Passgenauigkeit
