200G QSFP DD LR4 10km

The ACT QDD-200-LR4-LP10 is a high-performance 200 Gb/s QSFP-DD optical transceiver designed for next-generation data center and service provider networks requiring high bandwidth and extended reach. Supporting 200GBASE-LR4 with four LAN-WDM wavelengths over single-mode fiber, the module enables reliable transmission distances of up to 10 km, making it well suited for data center interconnect (DCI), metro aggregation, and high-capacity enterprise applications. Built on PAM4 modulation with a lane data rate of 53.125 Gb/s, the transceiver complies fully with IEEE 802.3cn 200GBASE-LR4, QSFP-DD MSA, and CMIS standards, ensuring broad interoperability with leading network platforms. The module integrates LAN-WDM lasers and PIN receivers in a compact QSFP-DD form factor with LC duplex connector, while maintaining a maximum power consumption of 10 W for efficient thermal performance in high-density environments. Designed for operational reliability, the ACT QDD-200-LR4-LP10 supports comprehensive Digital Diagnostic Monitoring (DDM), allowing real-time access to critical parameters such as temperature, voltage, bias current, and optical power. With the compliance with EU Directive 2015/863/EU (RoHS), this transceiver provides a robust, standards-based solution for scalable 200G optical deployments.

Note:

1.       Average launch power, each lane (min) is informative and not the principal indicator of signal strength. A

          transmitter with launch power below this value cannot be compliant; however, a value above this does not

          ensure compliance.

2.       Even if the TDECQ < 1.4 dB for an extinction ratio of ≥ 4.5 dB or TDECQ < 1.3 dB for an extinction ratio of < 4.5 dB,

          the OMAouter (min) must exceed this value.

3.       The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level.

4.       Average receive power, each lane (min) is informative and not the principal indicator of signal strength. A received power below this value cannot be compliant; however, a value above this                does not ensure compliance.

5.       Measured with conformance test signal at TP3 for the BER 2.4E-4.
