Cisco SFP-25G-ER40-S互換 25GBASE-ER SFP28モジュール(1310nm 40km DOM LC SMF)

Easy purchase and fast delivery. Cisco switches identify these FS modules quickly and perform well. I’ll continue to buy them next time.

FS is new to us. We finally bought these modules for impressed by their professional support and quality assurance. We used them in our new program and all go well. For such a long transmission link over 30km, the signals are still so satisfying. They fit well with our future network building needs.

We have been purchasing from FS since the establishment of the office. Now we upgraded to 25Gbps and couldn't be happier. Their customer support is fantastic and their maintenance guys always get the job done.
