2x GE to 1x 2.5G Muxponder

Lightem 2-port Gigabit Ethernet Multiplexer aggregates 2x Gigabit Ethernet services into 1x 2.5G uplink, reducing the conversion CAPEX and increasing the fiber utilization effectively.
The multiplexer can be used either in point-to-point topology functioning as a media converter for transporting 2 Gigabit Ethernet services over one fiber or in CWDM system working as a wavelength converter for extending the system’s transmission capacity. It is equipped with 3x SFP based ports: 2x Gigabit Ethernet service ports and 1x 2.5G uplink port, enabling a flexible application as required and realizing a cost-effective remote management. Additionally its advanced features such as downlink and uplink loop back, auto laser shutdown and remote network management provide carriers a flexible, reliable and cost-effective two Gigabit Ethernet over one wavelength conversion solution.
