50G SFP56

50G SFP56 BR10/BR40

The demand for optical transceivers that achieve low power consumption, high capacity, and ultra-low latency is increasing as part of the proliferation of next-generation networks.
NEC's 50G SFP56 optical transceiver, compared to optical transceivers that use analog CDR and DSP, offers better power consumption efficiency and enables high real-time communication. It can achieve twice the data transmission capacity of the 25G SFP28 optical transceiver.

Furthermore, it has the same form factor as existing SFP modules and the same electrical interface as SFP+ and SFP28, allowing for flexible configurations according to customer needs.

We offer products that support long-distance transmission of 10km/40km and BiDi (single-core bidirectional) products that enhance fiber utilization efficiency.

NEC contributes to the further expansion of customers' high-capacity networks with the 50G SFP56 series.
