Ordering Information
NS-280FX 8 x SFP Slots with 2 Giga Unmanaged Ethernet Switch





NS-280FX is a unmanaged SFP switch, each SFP port especial designed support high power source for feeding high power consumption SFP module as VDSL2-SFP / module, if install them it can be became a unmanaged IP DSLAM, or mixing install VDSL2-SFP / module plus Fiber optical module to extend your networking services and applications to farther places. NS-280FX also supports isolation function on SFP port for security, which can be easily configured by slide switch on front panel. There are lots of Multiple ports SFP switches in the market always power source is not enough to driver VDSL2-SFP / module or encounter overheat issue. Therefore, we put lots of effort for power source and good heat dissipation as NS-280FX's SFP slots are separated to each other, and build in two internal fans as well as special ventilated design for metal housing, to prevent SFP module overheat issue. With high performance and easy installation, NS-280FX can be utilized in ISP network solution for FTTdp(Fiber to the distribution point), FTTC (Fiber to the Curb) and FTTB (Fiber to the Building), also for SOHO application.
