1.25/2.5/3G Modules

1.25/2.5/3G Modules are standardized optical transceivers designed to support foundational data transmission rates, specifically 1.25 Gigabit (GbE), 2.5 Gigabit (OC-48/STM-16), and 3.0 Gigabit (Fibre Channel) applications. They provide the essential electro-optical conversion for these intermediate speeds, bridging the gap between legacy Gigabit networks and modern 10G+ infrastructures. Widely used in enterprise network upgrades, storage area networks (SAN), and carrier SONET/SDH transport, these modules are fundamental for enabling flexible, reliable, and cost-effective network evolution.
