Cisco GLC-SX-MMD Compatible 1000BASE SX SFP transceiver module is equipped with an LC duplex connector, which is high-performance, cost-effective, supporting 1.25Gbps data rate and 550m transmission distance over multimode fiber (MMF). It is verified to interoperate with original Cisco switches, including the Nexus 9200/9300 and the Catalys 9200/9200L/9200CX/9300/9300X/9300L/9300LM/9400/9500/9600 series, etc. QSFPTEK 1000BASE SX transceiver is compatible with the IEEE 802.3z 1000BASE-SX standard.
This Compatible 1000BASE-SX SFP fiber optic transceiver module consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA), and an MCU control unit. All QSFPTEK manufactured 1G SFP optical transceivers satisfy class I laser safety requirements.

The installation was smooth, and the module was recognised quickly. The connections were stable. We didn't lose any data or get disconnected. The performance of the optical power is consistent, and it works well with other equipment. This module is perfect for sending data at up to 1 gigabit per second over short distances and is very reliable.

The product description said there was a lot of stock, but after placing the order, I found out there wasn’t as much available, and some items needed to be restocked. It caused me some inconvenience. The customer service said the website isn't able to show real-time inventory for delays, which seems like something they could improve.

What I can make sure is this module is accepted by Cisco 9300. If you have the same switch as me, you can go with confidence.

These modules arrived on the forth day I placed the order with a decent package. It has already been tested on the Cisco devices, no issue so far.

I noticed it while searching on Google Shopping. Compared to similar products, its price and quality seemed quite good. I've already tested it on my Cisco switch for 1G access, and it worked without any issues.

Purchased a large quantity of 1G SFP modules, apart from the impressive quality of the product itself, the quality of QSFPTEK's customer service is also worth mentioning, Rachel has always been very helpful and patient in responding to the questions I've asked.
