Q:
What's the difference between QSFP28-BLR4-100G and QSFP28-LR4-100G?Is it worth paying extra more for BLR4?
by V***e on 05/11/2021
A:
The main differences between BLR4 and LR4 are power consumption, packaging technology, and application environment. The QSFP28-BLR4-100G with ≤3.5W power consumption, Adopt BOX packaging, the laser chip is sealed in a metal shell filled with inert gas, and will not easy to be affected by the changing of temperature and water vapor. If you plan to use the optics to 100G telecom and other areas with high requirements for temperature, airtightness, and reliability, etc, you can choose this BLR4 type; The QSFP28-LR4-100G with ≤4W power consumption, adopts COB packaging, the chip is attached to the board, and protected by epoxy resin glue, which reduces a lot of auxiliary components and saves costs, a cost-effective choice for the data center with constant temperature and humidity. hope it helps you to make a choice.

Not sure which model is better for me, one is $100 expensive than the other, I called and let them know my application, the customer service recommended the $599 one, and claim that this one is ideal for my telecom field. Very helpful, I've been able to test it out and it works perfectly! You've definitely earned a customer for life.
