Optical Line Terminal (OLT) is designed to provide broadband access over Passive Optical Network (PON).

GPON interfaces are used to connect the optical distribution network (PON). You can connect up to 128 subscriber optical terminals via a single fiber for each interface. Access to the operator’s transport network is provided through 10 Gigabit or combined Gigabit uplink interfaces.

OLT LTP allow operators to build scalable, fault tolerant “last mile” networks to ensure the highest safety standards. OLT manages subscriber devices, traffic switching and connection to the transport network.

Key features:

8хPON ports, 1U case
Hot-swappable redundant power units
Remote management via CLI, SNMP
Compliance with G.988, G.984.x and TR-156 standards
Ability to provide cable TV together with data transmission
Optimal solution for a small village or an apartment building
