A good news for all.

About QSFP, we have test the performance of it for many times, and it proves that the product performance of our QSFP is very successful and stable. 

This transceiver is a high performance module for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with 40Gbps bandwidth. Each lane can operate at 10.3125 Gbps up to 100 m using OM3 fiber or 150 m using OM4 fiber.These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector. The optical interface uses an 12 fiber MTP (MPO)connector. This module incorporates DONGWE Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.

About QSFP, we use famous American Gnum chip, so warranty is 3 years because of the good quality. Now we can have mass prodction. Welcome to contact us.
