 Product description OLT-1840's Optical Line Terminal (OLT) adopts GiGA Ethernet Passive Optical Network (EPON) technology. It is a compact chassis with L2/L3 GiGA switching and routing function. All the functional components are modularized design and it supports hot-plugging with plugging and playing. 1~8 pieces of GiGA optical port or electrical port are optional in the uplink port, which provides a direct optical interface for the Ethernet/IP network core. 40 pieces of EPON optical port are optional in the down link port. Through a passive optical Network (PON), an optical Network unit link (ONU),it can provide final transmission with bandwidth up to 1Gbps for the user.
OLT-1840, with the telecommunication-grade safe reliability and network management, also combines with the flexibility, high speed and economical efficiency of the EPON network-building. Besides, based on the high quality and high P/P ratio of Huatai products, it is an optimal transport platform for triple-play service in FTTx fiber access network.
