      Been using this 100G SR4 QSFP28 module in my Juniper QFX5130 for a couple weeks now. Works like a charm – plugged it in and it just worked. Solid performance, no hiccups. Really happy with the purchase, eh!

      Urgently needed a batch of 100G SR4 modules for our company project. When we inquired about them on the official website, we received full assistance from Wendy, our customer service representative. She not only quickly confirmed compatibility with my Juniper MX304, but also provided detailed MPO patch cord selection recommendations. The modules passed all tests immediately upon arrival, resolving our urgent need. They are a truly professional and reliable partner!

      J'ai acheté une paire de SR4 et ils fonctionnent très bien sur mon EX4400-48T. J'ai aussi acheté leur carte de codage, car j'ai plusieurs types d'interrupteurs, ce qui est pratique pour les réutilisations ultérieures. C'est génial!
