GLC-BX80-U-I= Use Case
Enterprise Campus Backbone Extension Over Single-Fiber Link
In a multi-building corporate campus, IT teams deploy GLC-BX80-U-I 1000BASE-BX80 SFP 1490nm modules to connect disparate switches over up to 10 km using a single strand of fiber. This bi-directional SFP halves fiber cabling costs, simplifies rack-to-rack connectivity and delivers full-duplex 1 Gbps throughput—ensuring seamless VoIP, video conferencing and cloud access with minimal infrastructure investment.
Metro Ethernet Service Provisioning for Telecom Operators
Telecom providers integrate GLC-BX80-U-I 1000BASE-BX80 SFP 1490nm transceivers into OLT/ONT platforms to deliver symmetrical gigabit Ethernet to business customers across metropolitan areas. The 1490 nm single-fiber design supports up to 10 km reach, reduces fiber-route complexity and boosts network reliability—enabling rapid service activation, lower CAPEX and SLA-grade performance for enterprise subscribers.
Data Center Disaster-Recovery Link with Single-Strand Fiber
A financial services firm establishes a disaster-recovery link between primary and secondary data centers by deploying GLC-BX80-U-I 1000BASE-BX80 SFP 1490nm modules on their core switches. Leveraging bi-di 1 Gbps connectivity over a single fiber strand, the solution delivers low-latency replication, simplifies failover testing and reduces operational cost—ensuring continuous data integrity and compliance with zero-downtime recovery objectives.
