Looks and feels sturdy. Doesn't seem to cause any loss of data transmission, although I didn't do any rigorous quantitative assessment. Just didn't feel any data transmission issues were occurring.

I am totally amazed by the so competitive price for the Transceiver Module. I bought 4pcs for test in advance, which work well on my switches. The price is much cheaper than original. What's more, the quality is pretty well, which has life warranty for it. Great product.

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.
