Key Features of Brocade E1MG-CWDM20-1370 Compatible LINK-PP 1.25G SFP
Brocade E1MG-CWDM20-1370 Compatible LINK-PP SFP module combines standardized optical hardware, dedicated wavelength routing, and long-range connectivity into a unified transceiver design. It integrates precision digital diagnostics and fiber-saving multiplexing capabilities to streamline single-mode network operations.
This module features a hot-pluggable SFP footprint that allows seamless installation without powering down host switches. Full compliance with the SFP Multi-Source Agreement (MSA) ensures broad interoperability across standard network equipment ports.
E1MG-CWDM20-1370: 1 Gbps Connectivity for Fiber Expansion & Mux Systems
Data transmission delivers a 1Gbps line rate to satisfy bandwidth demands across enterprise backbones. This throughput level makes it well-suited for interconnecting distribution switches, edge routers, and CWDM multiplexer channels.
E1MG-CWDM20-1370 Module with CWDM Technology for Fiber Efficiency
Coarse Wavelength Division Multiplexing splits individual data channels across shared fiber pairs to maximize existing infrastructure capacity. Network operators can significantly scale overall bandwidth without the high cost of laying new optical cabling.
E1MG-CWDM20-1370 Module with 1370nm Wavelength
A dedicated 1370nm operating channel provides accurate spectral spacing to prevent optical crosstalk in multi-channel configurations. The integrated CWDM DFB laser delivers stable spectral output to maintain clean optical signal pathways.
Long-distance reach spans up to 20km over standard single-mode fiber using an internal PIN photodetector. This extended optical power budget easily bridges wide campus networks and metro access distribution links.
