H!Fiber.com ASF-GE-T-Cisco-10pcs-HF(EU)

Used between a Netgear GS110 and GS728TP and works a treat, plug and play, both switches identified the modules with no problems and within 5 seconds were happily talking to one another. Good price

Good quality never had an issue with them

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 packagingCons:- SFP modules don't report their temperature

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

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

It bought these together with an MikroTik CRS305-1G-4S+IN switch with SFP+ ports, and it worked flawlessly after changing a setting in the switch! I am new to this and wanted to connect parts of my old 1Gb home network to my new 10Gb, and the customer service told me to turn of auto negotiation and manually set the speed to 1Gb and it started to work right away! The product works just as advertised and was very affordable.

Great product. Works as expected on my home Ubiquiti Unifi switches

Picture is misleading. Hence the low rating. It came in a plastic bag. Tin not mentioned, but as it is showing in the picture. The advert is misleading.Not tested gbics yet.
