TRENDnet SFP Multi-Mode LC Module, Up to 550m (1804 Ft), Mini-GBIC, Hot Pluggable, IEEE 802.3z Gigabit Ethernet, Supports Up to 1.25 Gbps, Lifetime Protection, Silver, TEG-MGBSX

Cheap alternative to the Cisco product for their small business switches. Installed 2 connecting 2 SG300-10PP switches with a 100m OM3 LC-LC fiber with no problems. I have yet to see how it performs in terms of longevity.Edit: 1 year later and these modules have been solid. No problems whatsoever.

I can't believe how easy it was to connect fiber optics. I am using these to connect two network switches approximately 500 feet apart. It was plug and play with no programming. Make sure your cabling, SFP module, and hardware specifications are aligned.

I had two media converters that just would not cooperate. I finally figured out one of them was flashing failure codes. I had one of these transmitters laying around and ordered a 2nd hoping the dell switch and the linksys switch would use the same transmitters. Nope. The linksys works with these. Dells do not. I ended up using the remaining working media converter on the dell end and one of these in the linksys end at the remote office. So I have a spare for now. I have one more linksys switch that I can use the spare in. I also found a spare transmitter for dell so I have just what I need for another temp building being brought in just a few months.

At 120 meters it rock with the companion TRENDnet 5-Port Gigabit Compact Metal Desktop Switch with SFP Slot, TEG-S51SFP. Price point per foot is quite reasonable and length pre made make the fiber within reach.Besites anything over 100 metes in cat6 is a crap shoot.Also bring your network into 2025 speeds of fiber provider with 1GB up/down.

Works perfectly. Chosen by recommendation and it came through. Used in a corporate network to link-convert a connection for two buildings and 48 port system. I attached it in a few minutes and it was up and running from the very second it got turned on. It has now been in use for a while and is easily recommended for business use. Great job. (Used with TRENDnet SPF Media converter)

I ordered these for Cisco Meraki switches for fiber connections. Haven't had any issues whatsoever with these modules. They say you may have issues calling in for tech support with Meraki since this is a non Cisco part but will worry about that when the time comes. The price difference between this and Meraki is worth the headache I may or may not have. Installed close to 60 Cisco Meraki APs and no problems with fiber connections between building using these GBICs.

This product worked great. I purchased it to use with the TrendNet TFC-1000MGB and it works like a champ. No setup, just plug and play. It has been in service well over a year now, and not a single glitch. I will buy them again for sure.

Plugged right into Netgear GS728TP switch without any issues. Used the TRENDnet PCIe adapter with this as well to provide a true fiber connection between our server and network switch. No issues so far and can see an obvious improvement with network speeds.
