NADDOD QDD-400G-LR8 optical transceiver module features duplex LC connectors and supports transmission distances of up to 10 km over single-mode fiber. It is fully compliant with IEEE 802. 3bs and 400GAUI-8 / CEI-56G-VSR-PAM4 standards. This transceiver adopts PAM4 modulation, a QSFP-DD form factor. The QSFP-DD OLS is a pluggable open line system solution that can be directly hosted on a Cisco router. The Cisco ® QSFP-DD Open Line System (QSFP-DD OLS) is a pluggable optical amplifier module that, together with the channel breakout options (described later), provides a simple yet powerful open. Amphenol's QSFP-DD Linear Pluggable Optical (LPO) Transceiver delivers low-latency, high-bandwidth PCIe ® Gen 5. 0 over optical link, enabling scalable server disaggregation and efficient rack-to-rack interconnects ideal for AI/ML and rack-scale data center expansion.
