400G ER1 QSFP-DD 45km Unamplified Point-to-Point

Product Overview

45km Unamplified

Connect sites up to 45km apart with 400G coherent wavelengths over dark fiber without optical amplifiers.

Point-to-Point Simplicity

Direct fiber connections with no DWDM line system required, reducing complexity and cost for campus and metro links.

400G Capacity

Full 400 Gbps throughput per wavelength for high-bandwidth campus extensions and inter-building connections.

QSFP-DD Pluggable

Standard pluggable form factor for deployment in Cisco routers and switches with QSFP-DD ports.

Cost-Effective

No amplifiers, no DWDM mux/demux, no line system management. Simple and affordable 400G connectivity.

Coherent Technology

Coherent detection enables reliable transmission over longer distances than direct-detect alternatives.

Features and Benefits

Simple 400G connectivity without amplification.

The 400G ER1 delivers point-to-point coherent connectivity up to 45km with no line system required.

45km Reach

Unamplified coherent links up to 45km over standard single-mode fiber.

No Amplifiers Needed
