Extend Your Network's Reach with High-Performance Fiber Connectivity

The TP-Link TL-SM311LM Gigabit SFP Module is a high-performance, multi-mode fiber optic transceiver designed to extend the transfer distance of your network. This MiniGBIC (Small Form-factor Pluggable) module is the ideal solution for expanding your network over longer distances, offering a reliable and cost-effective way to enhance your networking infrastructure. By converting a standard Gigabit Ethernet signal into a fiber optic signal, you can overcome the distance limitations of traditional copper cabling.

Seamless Integration and Broad Compatibility

Designed for maximum compatibility, the TL-SM311LM works flawlessly with a wide range of TP-Link JetStream switches and the MC220L media converter. Its hot-swappable design allows for easy installation and removal without powering down your network equipment, ensuring uninterrupted network availability. This module supports a data rate of 1.25Gbps, providing ample bandwidth for your demanding network applications.

Reliable Long-Distance Data Transmission

The TL-SM311LM is capable of transmitting data up to 550 meters using 50/125µm multi-mode fiber, and up to 275 meters with 62.5/125µm multi-mode fiber. This makes it an excellent choice for connecting buildings, departments, or remote workgroups within a campus or enterprise environment. The module operates at an 850nm wavelength and features an LC/UPC port type for a secure and reliable connection.

Best Cream!!
Love this stuff! I got this because menopause was killing my skin. It was awful! Itchy, red and dry. I couldn't sleep it was so bad. I found this, and it's literally the only thing that actually helped. I went through my first jar quickly, no you don't need much, but my rash was all over my arms, neck and chest. After my second jar and using it a few times a day, my rash is gone! Some people may not like the smell, but I think it's actually nice. It's not greasy, and I don't feel gross after putting it on. I hate greasy creams. On my third jar now! This one is lasting much longer since I don't need it as much.

Good Relief, But a Little Pricey
I don’t usually write reviews, but I felt like this cream deserved one. I’ve tried so many products for dry, itchy eczema patches, and most either felt greasy, burned when applied, or just didn’t do much. Puriya has been such a refreshing change. The texture is smooth, it absorbs quickly without leaving that sticky feeling, and within a couple of days my skin felt calmer and the redness started to fade. What I really like is how versatile it is. I’ve used it on flare-ups, random dry spots, and even my hands when they get irritated in the summer. It feels gentle but still effective, and I don’t need to use a ton for it to work. The only reason I didn’t give it 5 stars is the price. It’s a little on the higher side for the amount you get. I also find myself reapplying a bit more often than I’d like. But overall, it’s one of the better creams I’ve tried, and I’ll definitely keep using it.

Not good for eczema
This cream shouldn't be described as an eczema cream. Eczema is usually colonized by s. aureus bacteria, and you need a powerful anti-bacterial substance in your skin cream in order to combat it. Neem oil or manuka honey both have strong anti-bacterial effects, and I recommend getting a cream with one of those ingredients if you have eczema. This Puriya cream is helpful for moisturizing dry skin to prevent eczema. However, it won't help to stop eczema once you've got it. That said, customer service was very helpful and gave me a refund for the product after I complained.

Very nice and moisturizing on the skin but didn't do much repairing. Overly expensive for nothing.
