Cudy's CD-SFP-SMB is your answer for efficient and cost-effective single-mode fibre deployments! These bi-directional modules redefine connectivity standards with a powerful design optimised for 1.25 Gbps transmission over distances of up to 20km.

The CD-SFP-SMB modules are sold as a pair and feature a smart SFP package with LC connectors, ensuring cross-vendor compatibility. What distinguishes them is their novel application of bi-directional technology, which enables duplex transmission on a single fibre by utilising two distinct wavelengths for TX and RX on the same optical strand. This not only improves performance but also significantly lowers installation costs.

Choose between the SM100GSB-20A with a 1310nm FP laser and a 1550nm PIN photodetector or the SM100GSB-20B with a 1550nm DFB laser and a 1310nm PIN photodetector to meet your specific requirements.

These modules provide dependable performance because they are powered by a single +3.3V power supply and have an LVPECL-compatible data input/output interface. The CD-SFP-SMB provides a strong and secure connection thanks to its low EMI and excellent ESD protection. These modules prioritise environmental sustainability while adhering to RoHS and SFF8472 standards.

Nice Glow Just Sticky
Color: 03 Glistening Bronze
I was really excited to try this body glow oil, especially since it has SPF 45, getting sun protection and a bronzed shimmer all in one sounded perfect. The color is beautiful and gives a nice glow without looking too glittery, which I appreciate. However, it does feel a bit sticky right after application. I ended up lightly dusting some setting powder over it, which helped a lot to take down the tackiness and make it feel more comfortable throughout the day. Just a heads-up: you don’t need a lot of product, start with a small amount and build up if needed. It absorbs fairly quickly but still leaves that dewy finish, so it might not be ideal if you’re not into that slightly glossy feel. Overall, though, I really like the effect, especially for photos or a night out. Just takes a little trial and error to get it to work how you want!

Pretty sheer sparkle for your skin
Color: 02 Diamond Platinum
I really enjoyed this product. Normally I am not a glitter person but this is not like normal glitter products. You dont end up with glitter everywhere forever. The sun protection is not great, though I did not purchase for that reason. Definitely use regular sunscreen and then apply this. It is great for festivals, concerts, renfaire etc.

Gives a glow
Color: 03 AMBER
Doesn’t give as much of a shimmer but more so a glow and evens out skin tone.
