The HL7301 system is an OLT System for B2B/B2C ultra-wideband and supports various services such as Internet access, voice, and video. The existing xDSL or cable-modem equipment had a disadvantage as the transmission distance increases, the bandwidth decreases. HL7301 is equipment that solves the problems of existing devices, and it is possible to configure a network in the form of FTTB  or FTTH as well.

 The HL7301 system is an optical subscriber equipment using XGS-PON(10-Gigabit-capable Symmetric PON) and G-PON (Gigabit-capable PON) optical transmission technologies that support multi-drop, enabling economical and efficient use of optical lines. In addition, it provides stable high-speed Internet services by using only passive optical devices in the optical distribution network connecting the Central office and each ONU or ONT.

 The HL7301 system supports 8 ports ANY-PON (*note1) or Combo-PON(*note2) interfaces on the same PON port. It also offers up to four 10/25 GbE uplink network interfaces. The HL7301 system can be installed in a standard 19-inch rack and is 1RU (44 mm) in height to efficiently utilize the front panel space of the rack.

 It supports Layer 2 switching, Layer 3 routing, and supports multicast functions for IPTV service. It supports QoS(Quality of Service) functions to provide traffic quality according to the subscriber's application. Through time synchronization of IEEE1588v2 and Sync-E (Synchronous Ethernet) functions, it provides a specialized application for mobile fronthaul and backhaul.
