Key Features of Brocade E1MG-CWDM20-1310 Compatible LINK-PP 1G SFP
Brocade E1MG-CWDM20-1310 Compatible LINK-PP module is a commercial-grade 1G SFP optical transceiver utilizing a 1310nm CWDM wavelength to transmit data over single-mode fiber up to 20km. It combines a duplex LC interface, built-in digital optical monitoring, and full MSA compliance to deliver reliable point-to-point network links.
This optical transceiver is engineered with a standard hot-pluggable SFP footprint to ensure easy installation without powering down host systems. It fully complies with the SFP MSA to guarantee broad physical and electrical interoperability across standard networking equipment.
E1MG-CWDM20-1310: 1 Gbps Connectivity for CWDM Site-to-Site Links
Operating at line rates up to 1.25Gbps, this module delivers full-duplex Gigabit Ethernet connectivity across interconnected local and remote network locations. The sustained 1Gbps channel bandwidth ensures stable point-to-point data transmission between facilities without packet loss or signal degradation.
E1MG-CWDM20-1310 Module with CWDM Technology for Fiber Efficiency
Coarse Wavelength Division Multiplexing allows multiple data channels to operate over shared optical cabling by multiplexing distinct wavelengths. This deployment strategy helps network operators expand carrying capacity without the high capital expense of leasing extra dark fiber.
E1MG-CWDM20-1310 Module with 1310nm Wavelength
Operating on a standardized 1310nm optical channel, the internal CWDM DFB laser provides precise wavelength stability within the ITU-T spectral grid. This clean optical output minimizes channel crosstalk when passing through passive optical multiplexers and demultiplexers.
A high-sensitivity PIN receiver pairs with single-mode fiber to sustain clean optical power budgets over long spans reaching 20km. This 20-kilometer optical reach covers the physical span requirements typical of campus backbones and intermediate-reach metro distributions.
E1MG-CWDM20-1310 Module with Duplex LC Interface
The industry-standard duplex LC optical connector provides a secure mechanical latching mechanism to prevent accidental disconnects in dense switch racks. Its small form-factor footprint optimizes port density on patch panels while facilitating direct connections with standard optical patch cords.
E1MG-CWDM20-1310 Module with DOM for Real-Time Monitoring
Built-in Digital Optical Monitoring (DOM) compliant with SFF-8472 allows network operators to easily monitor vital metrics like real-time temperature, optical power, and laser bias current. This continuous tracking helps spot and resolve potential link issues early, ensuring steady performance and preventing unexpected downtime.

A:
While 14km is well inside the nominal 20km distance, multiple patch panels and splices introduce extra insertion loss. It is usually best to check that the total calculated attenuation on your fiber path remains comfortably within the optical budget between the transmitter output and the -24dBm receiver sensitivity.
