OnAccess7724D is a dual fiber version "triple play" Optical Line Terminal (OLT). It is a 24+ 4G high-performance managed Layer 2 "triple play" Optical Ethernet switch with CATV optical signal splitting function. OnAccess7724D provides an ideal low cost solution to deliver "triple play" services (data, voice and CATV) over dual single-mode fiber for fiber-to-the-home (FTTH) or fiber-to-the-building (FTTB) applications. OnAccess7724D offers up to 24 100Base-BX10-D ports and 24 CATV optical signal output ports to be connected to FirstMile's OnAccess4xxD or OnAccess7702D series optical network unit (ONU) at the user's premise. It also offers two optional SFP based 1000Base-X fiber optic ports and two 10/100/1000Base-TX RJ45 copper ports for fast connection to the core data network, as well as one CATV optical signal input port.

OnAccess7724D is targeted at the emerging market of Ethernet based “triple play” FTTx. It has a rich feature set to meet the requirements of a wide range of applications, especially those of the access network and the small-and-medium-scale customized network. Its optional dual power supply provides power redundancy for high-reliability applications. OnAccess7724D is low-profile with a standard rack-mount size. It achieves the highest fiber port density within a single rack, providing users with the best performance/price ratio

The network management function on OnAccess7724D allows administrators to easily configure features, monitor performance and troubleshoot the switches using a standard RS-232 port, Web browser, Command Line Interface (CLI) or a Simple Network Management Protocol (SNMP)-based network management platform
