Cisco GLC-BX-U Compatible 1000BASE-BX-U BiDi SFP 1310nm-TX/1550nm-RX 3km Transceiver Module

I recently purchased this 1G optical transceiver for my home office and have been very impressed with its performance. The installation process was quick and easy, and the signal quality is excellent.

The price is cheap and the quality is good. I asked colleagues around me to recommend this transceiver. I bought it and tried it~

Very fast delivery, it only took me five days to receive my package, these plug and play SFP BiDi modules can be used directly on my Cisco switch. great quality and service, both Cisco GLC-BX-D Compatible 1000BASE-BX-D have very good quality, and these have been tested and verified by me

IT support gave us a very simple, efficient, and no dramas service, which is what we really wanted. IT support told us how to properly set up the BiDi links and how to use the BX-U and BX-D modules. We ordered 10 1G SFP BiDi modules this time and they are working great without any problems!

During our purchase process, Talia, the customer service person, was able to tell me very quickly which modules would work with my switches, all of which support QSFPTEK's BX-U or BX-D 1G BiDi optical modules. This is amazing and provides more flexibility than the original optical modules, which can continue to be used if we need to replace the equipment in the future!

These are great. I have been using them in mikrotik switches and routers for more than half a year, and they work very well. I will continue to buy them this time.

Great product and cool packaging. It came in a very sturdy tin. Reasonably priced and it works without a problem on my Cisco switch.

I have bought 10G transceivers here in the past and they've always worked great. These are no exceptions. Highly recommended! Performs great between netgear GS716T and GS110TP.

I have been sourcing 1000BASE-BX BiDi SFP from QSFPTEK for resale since last year. Working with QSFPTEK for a long time let me know that the quality and price are really attractive. Also communicating with QSFPTEK for a long time, I learned that they already have high-end test centers from 1G to 100Gbps including Cisco, Juniper, Arista, Brocade. Talia told me that each of their optical modules is well tested before they leave the warehouse, which can guarantee their 100% performance, and, of course, I can guarantee my business and look forward to long-term cooperation with QSFPTEK.
