GPON interfaces are used to connect the passive optical network (PON). Up to 128 subscriber optical terminals can be connected to each interface via a single fiber. The access to the operator transport network is provided via 10 Gigabit or combined Gigabit uplink interfaces.
OLT LTP allows operators building scalable, last mile fault tolerant networks to ensure the highest safety standards. OLT manages subscriber devices, traffic switching and connection to the transport network.
Broadband subscriber access using FTTH technology is the highest quality version of the Triple Play service delivery, as it provides high data rates over long distances.
The main advantage of PON technology is the lack of electrically powered active nodes within the section from OLT to ONT, which greatly reduces the network operating cost. Furthermore, PON technology saves on cabling infrastructure by reducing the total length of the optical fiber, as only one fiber for a group of up to 128 subscribers is used within the section from the central node to the splitter.
OLT LTP rev.C/rev.D support two hot-swappable power modules with the ability of automatic transfer to a redundant module.
