Ciena NTTA12BAE6 C 40GBASE-LR4 QSFP Transceiver

The Ciena NTTA12BAE6 C is a 40GBASE-LR4 QSFP+ optical transceiver module that enables high-density, long-distance 40 Gb/s Ethernet links in data centers and carrier networks. In QSFP+ form factor, this pluggable transceiver uses 1310 nm optical wavelengths and supports link distances up to 10 km over single‑mode fiber, with duplex LC connectors and digital optical monitoring (DOM) for real-time health and diagnostics. It is designed for 40GBASE-LR4 operation over SMF, delivering the performance expected from Ciena’s LR4 family and providing visibility into link health through DOM. The NTTA12BAE6 C designation identifies the Ciena variant of the LR4 transceiver, ensuring compatibility with equipment that accepts LR4 QSFP+ modules. Typical deployment scenarios include uplinks between switches and interconnects over SMF with LC duplex interfaces where 1310 nm transmission and 10 km reach are required.
