Transceivers type QSFP-100G-4WDM-S
Use a pair of these transceivers to directly connect my small studio to the office across the street via dark fiber. Although I only purchased two, the customer service was very professional and confirmed the wavelength and distance matching. The device (Cisco switch) recognized it perfectly and has been running smoothly for a month without any issues, saving me a significant amount of money.

This is not the first time I have purchased here. Their product page has a very detailed introduction, especially the connectivity application. I can buy accessories together, which is very convenient and affordable. The quality is also great. I have not encountered any quality problems in the previous module use.
