I finally decide to give LINK-PP Ethernet port a try, since they are not as expensive as an original module. The result makes me very satisfied. They work well with very low insertion loss on our equipment, and the connection is also very firm.

We had a large volume for 10/25/40G Transceiver Modules each month.always had good performance. This time our Account Manager told me that it had a big price reduction, so we purchased some more which can be used for six months. Surprisingly, we received the goods quickly. That's great.
