Supporting transmission distances of up to 120 km, this module is ideal for data center interconnect (DCI) and metro network deployments requiring high-capacity, long-haul optical links without the need for external transponders. Cisco QSFP-DD and OSFP 800G ZR/ZR+ digital coherent optics modules enable 800G traffic over amplified Dense Wavelength-Division Multiplexing (DWDM) links up to 120 km for 800ZR and over 1000 km for 800G ZR+. Built on IP-over-DWDM (IPoDWDM) principles, it directly integrates the IP packet layer with the DWDM optical layer using standardized, pluggable coherent optics. This. 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. On the host side, the module can accommodate a variety of signal types including 100GE, 200GE, 400GE, OTU4. A QSFP-DD form-factor OIF 400ZR and OpenZR+ MSA transceiver for 100 - 400Gbps Ethernet applications with a transmit power of 0dBm The TQD013-TUNC-SO is a high-performance QSFP-DD form-factor transceiver designed for long-reach 400G Ethernet applications.
