StarTech.com Cisco GLC-SX-MMD Compatible SFP Module - 1000BASE-SX - 1GbE Multimode Fiber MMF Optic Transceiver - 1GbE SFP - LC 550m - 850nm - DDM Cisco Firepower, ASR920, IE2000 , TAA (GLCSXMMDSTT)

Worked as expected. Great price and our Cisco 2960S accepted without issue. In general, I do believe quality comes at a price. However, someone has to explain to me why a Cisco-branded GBIC sells for over $300 when this is a tenth of the price and works just fine. The same for HDMI cables, but that's for another review and post.

Considerably cheaper than the Dell certified adapters and still work with the Force10's without any issue. If you run into problems, Dell won't support, of course; but I've yet to have a connectivity issue on s4810p's.

For the price and what the name brand ones cost you cannot pass these up. Work great and price is amazing.

Installed on an EnGenius Technologies 48-Port Gigabit PoE+ L2 Managed Switch with 4 Dual-Speed SFP (EGS7252FP) and works like a charm for the backbone connectivity between two of these network switches.

We have used these in many of our Cisco switches and had very good results.

Bardzo polecam ...

great

Did not work in my GS724Tv4 Netgear Switch

Inexpsensive and works trouble free - so more have been bought!

Hi, ich habe diesen SFP für meinen Cisco Meraki 220 2x erworben, um zwei Merakis zu kaskadieren. Dies ergibt eine galvanische Trennung zum Router und eine Klangsteigerung beim streamen. Super schwarzer Hintergund und Musikalität. Wers nicht glaubt, einfach mein Video auf YT schauen, dort wird der Klangvergleich gezeigt. Headquarter Audio Cheers Mike

Funziona anche con switch Netgear.Su questa porta non vengono abilitate le funzionalità Green e PoE, ma ciò era come da aspettative.

Funktioniert tadellos. Super schelle Lieferung. Ich bestelle wieder.

It works in a Cisco Switch
