Juniper Compatible QDD-400G-ZR4-FL Features


Juniper Compatible QDD-400G-ZR4-FL General Description

This product uses a 76-pin QSFP56-DD MSA QSFP56-DD Hardware Specification connector for all electrical interfaces with the host card, whereas the optical interfaces on the line side are provided through the optical receptacles on the QSFP56-DD. The module can be portioned into three functional parts: TX path, RX path and Control& Power block


The host interface is comprised of a total of 8 high-speed SerDes lanes. This allows module to support one interfaces for 400G application: an independent double 4-Lane mode client interfaces (for 400GbE application).

ESD

This transceiver is specified as ESD threshold 1kV for high speed data pins and 2kV for all other electrical input pins, tested per MIL-STD-883, Method 3015.4 /JESD22- A114-A (HBM). However, normal ESD precautions are still required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from the packaging and handled only in an ESD protected environment.


Laser Safety

This is a Class 1 Laser Product according to EN 60825-1:2014. This product complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice No. 50, dated (June 24, 2007).

Caution: Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
