how to install Finisar 40GBASE-SR4/10GBASE-SR 300m Gen3 QSFP+ Optical Transceiver

  • Prepare the system: Confirm that your chassis, switch, or server has a compatible QSFP+ slot and supports 40GBASE-SR4 and/or 10GBASE-SR optics. Power down the device if required by your maintenance policy, and ground yourself to prevent electrostatic discharge.
  • Handle with care: Keep the transceiver in its protective package until you’re ready to install. Avoid touching the optical interface and connector ferrules to prevent contamination and maintain optimal signal integrity.
  • Insert the transceiver: Align the QSFP+ module with the slot and slide it straight into the port until it clicks securely into place. Do not apply excessive force; if resistance is felt, remove and reinsert gently to ensure proper seating.
  • Connect the fiber cabling: Attach the MMF cable to the MPO connector as specified by your network design. Ensure correct fiber orientation and lane mapping to match the target interfaces, and verify that the connectors are clean and free of dust or debris.
  • Power up and validate: Restore power to the device and check the link status indicators or management software to confirm that the transceiver is recognized and that link negotiation is successful. Test traffic flow and monitor error counters to verify stability across both 40G and 10G lanes as needed.

Thank you VIVO
Color: Black, Size: Standard, Color: Black, Size: Standard
Between these cable management trays and the VIVO under desk UPS mount, I have completely tamed the cables at my desk. No more tangling my feet in cables when I stretch. No more messy, unkept appearance. Even with zip ties, I was never able to get anything close to this. It's truly amazing what the right hardware and a little bit of work can do. Everything you need is in the box. I do recommend drilling pilot holes, even in particle board or softer wood to make it easier to screw in, but the installation is dead simple and done right, no one will even know these trays are there. I should have done this years ago.

Perfect Solution for Desk Cable Clutter!
Color: White, Size: Standard
I’m super happy with the VIVO 2-pack under-desk cable management trays. They’re exactly what I needed to keep my workspace clean and organized. The 17-inch size is perfect for holding power strips, chargers, and all those messy cords that usually clutter up my desk area. Installation was a breeze — the trays come with all the screws and clear instructions. I mounted them under my desk in just a few minutes, and they feel really sturdy and well-built. The metal construction looks sleek and durable, and it holds everything without any sagging or bending. Now my cables are off the floor and totally hidden, which not only looks great but also makes cleaning so much easier. If you’re tired of tangled cords and want a neat setup, these trays are a must-have! Highly recommend!

Perfect cable management
Color: Black, Size: Standard
I set these up on my sit/stand office/gaming desk and trust me when I say I have a lot of cords, power blocks and what not going on. 2 27" monitors (both have DP and HDMI hooked up), two laptops, PS5, gaming speakers, iPad, docking station, phone charging station...and this thing holds all of the cables, blocks AND the Anker multi-plug with 12 outlets. No cords hanging, everything clean. Super easy to install, I totally recommend this product. I like it so much I bought another one for my girlfriend for her home office to get her all set up. You won't regret it

Use Velcro or Command strips and save yourself money
Color: Black, Size: Standard
These are high quality and are nice additions for the VIVO standing desks. However, they only fit slim power strips. My power strips were too wide to fit these. I ended up just using Velcro and Command strips to attach the power strip under my desk and purchasing cable management wires. In the end, I think it turned out much better than using these cable management trays and also saved me a significant amount of money.

Works for hiding cables
Color: Black, Size: Standard
Worked great to manage my cables to my pc setup. My double wide surge protector fit in there just right. Easy to mount with the holes and the bottom to fit a screw driver or power drill. Not too flimsy.
