Complete TWDM-PON ONU functionality in a compact SFP package





ZARAM TWDM-PON ONU STICK is a 10-Gigabit-capable Symmetric Passive Optical Network Stick type ONT in a compact SFP package with TWDM-Wavelength. The TWDM-PON ONU Stick provides a pluggable and multiple 10G interface for FTTx and wireless backhaul applications with a compact size and lower power consumptions.


By being plugged into the L2/L3 switch or CPE with standard SFP uplink port directly, the TWDM-PON ONUStick provides different wavelength data link over a single fiber.  Combining  Passive MUX with TWDM-PON ONU stick, can be connected up to 80Gbps bandwidth. Any standard Ethernet SFP+ switch port can simply convert to a TWDM-PON ONU port and interconnect to an existing TWDM-PON network with the insertion of the module. It is built in compliance with ITU-T G.989.x specifications, an industry standard witch defines TWDM-PON access networks.
