Key Features of Cisco DWDM-SFP10G-31.12 Compatible LINK-PP 10G SFP+
Cisco DWDM-SFP10G-31.12 Compatible LINK-PP module is a 10G SFP+ module that supports DWDM technology on a 1531.12nm channel for links up to 40km. It helps businesses expand network bandwidth over single-mode fiber while offering real-time monitoring and easy plug-and-play setup.
The transceiver features a hot-pluggable SFP+ footprint that allows seamless installation or replacement without taking host switches offline. Full compliance with the SFP+ MSA standard ensures direct interoperability across a broad range of multi-vendor networking equipment.
DWDM-SFP10G-31.12: 10 Gbps Connectivity for Enterprise Optical Rings
Dedicated 10Gbps transmission delivers stable throughput to handle data-intensive traffic across modern enterprise ring topologies. This bandwidth capability ensures uninterrupted data exchange between aggregation switches and corporate core nodes.
DWDM-SFP10G-31.12 Module with DWDM Technology for Fiber Efficiency
Dense Wavelength Division Multiplexing enables multiple independent channels to transmit over a single fiber pair simultaneously. This channel multiplexing drastically cuts cabling overhead and maximizes the carrying capacity of existing dark fiber runs.
DWDM-SFP10G-31.12 Module with 1531.12nm Wavelength
Operation at 1531.12nm aligns precisely with ITU-T Channel 58 on the standard 100GHz C-band frequency grid. A stable cooled EML transmitter locks the light source to prevent spectral drift and eliminate adjacent-channel crosstalk.
Single-mode fiber links can span distances up to 40km through a balanced optical power budget. This coverage makes it suitable for bridging distant metro facilities and multi-building campus networks without intermediate signal regeneration.
DWDM-SFP10G-31.12 Module with Duplex LC Interface
An industry-standard duplex LC receptacle provides a secure, low-loss mechanical connection for standard single-mode patch cords. Its push-pull latching mechanism simplifies cable routing and maintains tight alignment in high-density patch panels.
DWDM-SFP10G-31.12 Module with DDM for Real-Time Monitoring
Digital Diagnostic Monitoring (DDM) continuously tracks operational metrics including operating temperature, laser bias current, supply voltage, and optical power. These live telemetry values help technicians pinpoint emerging optical faults early and reduce costly network downtime.
Cisco DWDM-SFP10G-31.12 Compatible LINK-PP DWDM 10G SFP+ module meets strict international safety and environmental standards, holding certifications including ISO 9001, CE, RoHS, and FCC.
