      Have been using this 100GBASE-ZR4 module for a few weeks now and it is running well with stable rates. However, in addition to the hardware, the documentation support and configuration manual could still be optimized, in my opinion. All in all, this is a very reliable module and the overall performance is good for its price.

      I had a great time shopping here for the first time on the recommendation of a friend. I must say Talia saved me some extra time and money. The most important thing is the fast shipping by DHL. They even guarantee when my shipment will arrive. The quality of the product meets expectations, and we hope to reach a long-term cooperation.

      This item extended my network 100Gb link to 100km reach, which fits well in the long-haul point-to-point applications. Now two buildings 100g and 25g speed are stable. I will update my comments if any issues happens.

      We have already received this transceiver and performance well in our long-haul distance transmission. Before I decide to purchase it, I communicated with my Account Manager for a long time. From product introduction to stock situation, also the after sales service. She is very patient and helped me to better know about QSFPTEK. It's a good shopping experience, will be back again.
