SL-821T is dual-mode(XPON) ONT designed for delivery of telephone services, IP-based data services, Voice(VoIP) services,IPTV video services, and CATV video services to single-family home and small office/home office (SOHO) users. SL-821T supports automatic switching between GPON and EPON modes, offers 4 Gigabit Ethernet ports, 2 FXS ports, Wireless 11n 2.4GHz (2x2) and 11ac 5GHz (4x4) dual band concurrent, 1 CATV port. SL-821T is designed for indoor installation and can be desktop or wall-mounted. A single optical fiber carries upstream and downstream traffic over the PON between the OLT and the ONT. SL-821T is fully provisioned and managed from the OLT using PLOAM/OMCI and TR069.
WiFi signals are Coverage Throughout the house
External 6x 5dBi high gain antenna, through scientific and professional layout, through accurate debugging, set the best isolation interval between antennas, greatly reduce signal overlap, convenient signal transmission, so that the signal coverage is wider, the signal is stronger!
