The Cudy SM220 SFP-T 10/100/1000Mbps RJ45 Ethernet Module delivers dependable and high-speed wired network connections for enterprise, SMB, and advanced home networking environments. Fully compliant with the SFP Multi-Source Agreement (MSA), this copper transceiver supports Gigabit Ethernet and 10/100/1000BASE-T standards as defined in IEEE 802.3, ensuring seamless compatibility with a wide range of switches, routers, and network interface cards. Whether upgrading infrastructure or expanding connectivity, the SM220 offers a cost-effective and flexible networking solution.

Engineered for efficiency, the hot-pluggable SFP footprint allows quick installation or replacement without service interruptions. Consuming just 1.05W typical power, the SM220 helps reduce energy costs while maintaining optimal performance. Its compact RJ45 connector assembly and fully metal enclosure not only enhance durability but also reduce electromagnetic interference (EMI) for stable and interference-free connections.

The SM220 supports bi-directional data rates up to 1.25Gbps over Cat 5 or better cabling, with 10/100/1000BASE-T operation in host systems equipped with a 1000BASE-X interface. Using the SFP's RX_LOS pin for link indication, it provides reliable connectivity feedback to network administrators. The robust electrical design ensures minimal latency and consistent throughput, making it ideal for bandwidth-intensive tasks like VoIP, video conferencing, and large-scale file transfers.

With an operating temperature range of 0°C to +70°C, the Cudy SM220 is suited for diverse networking environments, from climate-controlled server rooms to active office floors. Its RoHS-compliant, lead-free construction ensures eco-friendly operation, while the single +3.3V power supply simplifies integration into existing setups. Perfect for upgrading to gigabit speeds or enhancing network flexibility, this module offers a dependable and scalable solution for modern networking needs.

Excellent monitor!!! Be aware that it does not have internal speakers.
Size: 24 inch 100Hz
Beautiful image. This monitor is excellent and I am very happy with it. However, you should be aware that it does not have any internal speakers and it does not have any audio input. It does have audio output for external speakers or headphones. For me, this was not a problem since I use a USB external speaker for better clarity. The lack of internal speakers was a surprise to me, but I suppose since the lack of speakers mentioned in the product description should have tipped me off.

Great Buy
Size: 24 inch 100Hz
I needed an monitor for my work office and I am glad I got it. It suits the job. The screen is nice and bright, clear, and runs smooth. It is easy to set up but I wish it could swivel around and had some height too it. Overall, It was a good buy for the 24 inch screen. I would definitely buy it again. The sound quality is great,no issues so far with the monitor at all.

Works as it should
Size: 24 inch 100Hz
I started a new job a few months ago and I get to work from home one day a week. They do not pay for you to set up a home office however, so I was looking for a cheap monitor for part of my set up. I came across this one and decided to try it out. I work in client service for a finance company so a lot of what I use it for is email, other conversational programs, and then our custodian software. I’m not doing anything crazy. I have it connected to a name brand laptop and it was very easy to set up with no issues. It turned right on. The picture quality is nice. Again, I’m not doing editing or anything on this so it works for what I need. It does NOT have speakers, so I do need to use the speakers on my laptop( which can be annoying), but again it’s not a deal breaker. I have been using it now for 5 months and it’s been working really well for my set up. I am thinking of getting a second monitor and I would get another of these but also I do want a speaker so I don’t know that I would get this exact version. For the price, if you are looking for something basic for normal work from home needs, this does the trick!
