Key Features of Dell CWDM-SFP-1610-20 Compatible LINK-PP 1.25G SFP
Dell CWDM-SFP-1610-20 Compatible LINK-PP module is a 1G CWDM SFP module designed for reliable single-mode fiber links. Operating at a 1610nm wavelength, it supports 1Gbps data rates over distances up to 20km through a standard duplex LC interface. The transceiver combines efficient wavelength multiplexing with real-time digital optical monitoring to streamline enterprise connectivity.
This transceiver features a hot-pluggable SFP footprint that enables seamless installation without interrupting active network operations. Full compliance with the SFP Multi-Source Agreement (MSA) guarantees broad interoperability across standard networking equipment.
CWDM-SFP-1610-20: 1 Gbps Connectivity for Distributed Network Nodes
Delivering line-rate Gigabit Ethernet throughput, this module provides stable 1Gbps data transmission for bandwidth-demanding systems. It is ideal for interconnecting edge switches, enterprise routers, and remote access terminals across distributed node architectures. The consistent speed helps prevent data bottlenecks in core-to-edge network links.
CWDM-SFP-1610-20 Module with CWDM Technology for Fiber Efficiency
Coarse Wavelength Division Multiplexing (CWDM) technology allows multiple optical signals to share a single optical fiber pair by using distinct channel wavelengths. By maximizing existing cabling infrastructure, it significantly lowers total fiber deployment costs. This approach enables operators to expand network capacity without running expensive new fiber lines.
CWDM-SFP-1610-20 Module with 1610nm Wavelength
Operating on a standardized 1610nm optical channel, the module fits precisely into 18-channel CWDM grid configurations. Its DFB laser ensures stable channel spacing and minimal spectral drift across commercial temperature ranges. This specific wavelength facilitates clean signal integration when multiplexed with other optical channels.
Engineered for medium-reach optical connections, the transceiver drives single-mode fiber links up to 20km without requiring signal amplification. A high-sensitivity PIN photodetector maintains low bit error rates across the entire optical span. This reach makes it well-suited for connecting campus buildings and regional distribution points.
CWDM-SFP-1610-20 Module with Duplex LC Interface
The industry-standard duplex LC connector ensures a secure, low-loss physical connection with standard single-mode patch cables. Its compact latching mechanism prevents accidental disconnections while maximizing port density on switch panels.
CWDM-SFP-1610-20 Module with DOM for Real-Time Monitoring
Digital Optical Monitoring (DOM) provides continuous telemetry for critical operating metrics in full compliance with the SFF-8472 diagnostic standard. System administrators can track laser bias current, Rx/Tx optical power, supply voltage, and operating temperature in real time. These diagnostic metrics help engineers detect link degradation early and prevent unpredicted network downtime.
