SFP Copper RJ45 Transceiver Gigabit Module 1000Base-T Compatible Cisco GLC-T/SFP-GE-T 2 Pack

Work perfectly in my Zyxel GS1900 switch.

Simple plug&play installation and a keen price, what's not to like!

Always work perfectly, I note they no longer come in a tin, but a plastic bag which is a shame as the tins are useful, and not nice having more plastic packaging to dispose of, but all good otherwise.

These 1000Base-T SFP Copper RJ45 Transceivers work perfectly in Cisco SG300-10 and Mikrotik CRS309 switches and were detected straightaway with no issues. I needed to force the speed to 1Gbps Full Duplex on the Mikrotik's 10GbE SFP+ ports though. Unlike most other SFP transceivers I've purchased before these come in a nice little metal tin with a foam cut out. I've never used HiFiber modules before, but despite the the name sounding like some kind of breakfast cereal they do seem to work fine and were the cheapest modules I came across on Amazon. My only criticism is that, unlike all my other SFP/SFP+ modules I have, these don't appear to report their temperature back to the switch. They do run a little warmer than the optical transceivers and would be nice to know what temperature. Pros: - Very good value for 2 SFP modules - Compatible with all devices I tried (Cisco SG300-10 and Mikrotik CRS309) - Decent quality packaging Cons: - SFP modules don't report their temperature

Great kit of sfp plugged into two separate switches and worked right away. DL switch and TP link switch. Fully recommend

Long term reliability unknown - item was selected on basis of price. Arrived well packaged in foam within a nice bespoke tin with sliding cover - what's not to like!

These worked first time in my Meraki Switch, great product at a good price. For reference I have the Meraki MS-220p switches and used these to connect the two of them together. Will be buying some more of these to expand the available switch ports.

Replaced a Netgear switch with the TP-Link model above but after finding out the SFP modules I had purchased for that didn't work in the TP-Link switch, I had to go hunting for modules that did. These do :)

J'ai acheté ces deux modules pour ajouter deux ports ethernet à un switch Netgear. Aucun problème, et un upgrade pas cher pour ce vieux switch.

Sin novedad. Todo bien

Funktionieren einwandfrei wie beschrieben im Switch

Ottimo articolo che rispecchia quanto illustrato in vetrina. Ho provato diverse modalità d’uso di questo prodotto su diversi hardware, quali switch di diverse marche, router, adattatori con modulo SFP etc. Hanno sempre funzionato regolarmente senza mai mostrare incompatibilità hardware o software.

Abordables et de bonne qualité. S'insèrent sans problème dans les ports SFP+ d'un routeur CRS305-1G-4S+in et fonctionnent correctement. Pour les activer, il faut fixer la vitesse de chaque port à 1 Gb/s ou moins. (Dans mon cas, l'auto-négociation ne fonctionne pas correctement avec la version 6.47.1 de RouterOS pour ces modules). J'ai 'intention d'en racheter une paire pour ne pas en manquer ... ;-)
