Key Features of Cisco DWDM-SFP10G-38.19 Compatible LINK-PP 10G SFP+
Cisco DWDM-SFP10G-38.19 Compatible LINK-PP provides 10Gbps data transmission for long-distance links up to 80km on a 1538.19nm wavelength. Equipped with a standard duplex LC interface, it supports hot-swapping and live digital diagnostics to ensure stable daily operation.
This transceiver features a compact, hot-pluggable SFP+ footprint that allows seamless installation and maintenance without powering down the host equipment. Fully compliant with standard SFP+ MSA specifications, it ensures broad mechanical and electrical compatibility across various networking platforms.
DWDM-SFP10G-38.19: 10 Gbps Connectivity for High-Capacity Fiber Expansions
Delivering consistent 10Gbps data rates, the module effectively addresses growing bandwidth demands across enterprise backbones and service provider aggregation links. It provides a stable and scalable throughput solution that supports heavy traffic loads in continuous point-to-point applications.
DWDM-SFP10G-38.19 Module with DWDM Technology for Fiber Efficiency
Dense Wavelength Division Multiplexing (DWDM) technology allows operators to combine multiple data channels over an existing fiber infrastructure. By operating on tight channel spacing, the module maximizes overall fiber capacity and significantly reduces total optical cabling requirements.
DWDM-SFP10G-38.19 Module with 1538.19nm Wavelength
The 1538.19nm center wavelength (Channel 49) corresponds precisely to the 100GHz ITU C-Band optical grid. A stabilized, cooled transmitter architecture guarantees precise wavelength locking and minimizes frequency drift during long-term operation.
Extended reach capability enables point-to-point optical communication spanning distances of up to 80km over standard single-mode fiber. An integrated cooled EML laser and high-sensitivity APD receiver work together to overcome substantial optical path attenuation across long-haul paths.

We deployed this LS-DW4910-80C 10G SFP+ module on a 70km inter-building link through a passive DWDM MUX. The -1 to +5dBm TX output with the high-sensitivity APD receiver gave us plenty of margin above the -23dBm sensitivity limit. Real-time DDM readings make span loss monitoring very easy. Highly recommended for long-range networking.
