ZTE f800 light cat is quite good. The fever is low and the internet speed is quite fast.

ZTE zxhn-f603 is a gigabit optical cat. ZTE ZXHNF60 1 supports GPON network protocol, which is a passive optical network with gigabit function. Great advantages of GPON: 1, longer transmission distance, using optical fiber transmission, and the coverage radius of access layer can reach 20 kilometers; 2. It can provide higher bandwidth for each user, 2.5G/ downlink/uplink 1.25G (physical layer); 3. It has strong spectral characteristics, and can separate multiple home optical fibers from a single optical fiber at the local end, saving optical fiber resources.
