DWDM-SFP-5655= Use Case
Metro Core Network Upgrade with DWDM-SFP-5655 (1556.55 nm, 100 GHz ITU Grid)
A national ISP integrates DWDM-SFP-5655 (1556.55 nm, 100 GHz ITU Grid) modules into its existing C-band line system to migrate metro core links from 10 Gbps to 100 Gbps per wavelength over 80 km of dark fiber. The precise ITU spacing enables seamless channel multiplexing and backward compatibility with 10G infrastructure. Outcome: network capacity doubles, OPEX per bit drops by 60 %, and new revenue-generating services launch 3× faster with zero fiber re-route.
Data Center Interconnect (DCI) Using DWDM-SFP-5655 1556.55 nm, 100 GHz Module
A cloud service provider deploys DWDM-SFP-5655 (1556.55 nm, 100 GHz ITU Grid) modules to establish a 60 km, low-latency 100 Gbps link between two data centers. The transceivers plug into existing DWDM mux/demux and EDFA amplification units, ensuring high OSNR and minimal channel crosstalk. Outcome: scalable bandwidth growth on demand, sub-1 ms round-trip latency, and simplified capacity expansion without additional fiber installation.
High-Frequency Trading Link with DWDM-SFP-5655 (1556.55 nm, 100 GHz ITU Grid)
A financial institution deploys DWDM-SFP-5655 (1556.55 nm, 100 GHz ITU Grid) SFPs for a 40 km direct optical path between its trading hub and the exchange. The narrow 100 GHz channel spacing and precise wavelength control minimize dispersion, delivering deterministic 100 Gbps throughput with latency under 500 µs. Outcome: ultra-low latency trading, full compliance with regulatory monitoring, and enhanced system resilience through coherent channel isolation.
