Operating at 1531.89nm over the 100GHz ITU grid, this duplex LC optical module combines exceptional spectral efficiency with real-time digital optical monitoring for seamless network management.
This 10G DWDM module features a hot-pluggable SFP+ footprint that allows rapid installation and field replacement without interrupting host system operations. Fully compliant with the Multi-Source Agreement, it guarantees broad physical and electrical compatibility with diverse networking hardware.
DWDM-SFP10G-31.90: 10 Gbps Connectivity for Metro Core and Aggregation
A continuous throughput of 10Gbps empowers metropolitan core switches and aggregation routers to handle bandwidth-intensive service traffic smoothly. Such consistent high-speed capability prevents bottlenecking during peak data demands across enterprise backbones and regional transport links.
DWDM-SFP10G-31.90 Module with DWDM Technology for Fiber Efficiency
Dense wavelength division multiplexing (DWDM) enables multiple discrete optical channels to run concurrently across a shared physical single-mode strand. By maximizing usable fiber capacity, network operators can dramatically scale their transport infrastructure without installing costly new dark fiber runs.
DWDM-SFP10G-31.90 Module with 1531.89nm Wavelength
Channel C57 operation at 1531.89nm aligns precisely with the standard 100GHz ITU-T C-band grid, preventing crosstalk interference with adjacent optical paths. Its cooled EML emitter delivers stable central wavelength lock even under varying ambient thermal conditions.
Extended reach up to 40km is achieved via an optimized optical power budget paired with single-mode fiber media. This point-to-point distance capability bridges distant campus buildings and distributed metro hubs without requiring intermediate inline optical amplifiers.

We used these SFP+ DWDM transceivers to bridge two campus distribution rooms through leased dark fiber lines. Optical loss was measured at -11 dBm on the far-end receiver, leaving comfortable headroom over the sensitivity threshold. Link renegotiation is instant after reboot cycles, making maintenance completely painless.
