The QSFP-DD 400G DR4 / 4x100GBASE-DR transceiver is a high-speed optical module supporting 400 Gbps aggregate data rate over single-mode fiber with four 100 Gbps lanes at 1310 nm up to 500 m.
Yes. The QDD-400G-DR4-JNP-C is fully tested and guaranteed compatible with Juniper routers and switches running supported Junos OS releases.
This transceiver operates over single-mode fiber (SMF) and supports link distances up to 500 meters at 400 Gbps using standard LC duplex connectors.
It uses four independent 100 Gbps channels at 1310 nm with transmit power between –1.5 and +5 dBm and receiver sensitivity down to –8.4 dBm, ensuring reliable 500 m SMF reach.
Simply slide the module into a compatible QSFP-DD port until it clicks. Verify link status via your Juniper device CLI or management interface to confirm successful handshake.
Yes. The module supports hot-plug capability, allowing insertion or removal without powering down the host device, as long as your Juniper platform supports QSFP-DD hot-swap.
Typical power consumption is 10 W per module. Actual power draw may vary slightly depending on operating temperature and channel activity.
The QSFP-DD 400G DR4 module uses four separate 100 Gbps lanes; no external MUX/DEMUX is required. Each lane operates independently over SMF.
Yes. It includes a digital diagnostics monitoring interface that reports real-time data on optical power, temperature, voltage and bias current via I2C/MDIO.
The module operates from 0 °C to +70 °C and 5% to 85% non-condensing humidity, making it suitable for standard data center environments.
No additional licenses are needed. Once inserted into a supported QSFP-DD port on a Juniper device, the module is automatically recognized and available.
Use the Juniper CLI command 'show interfaces diagnostics optics' to confirm firmware version and operational status. Ensure Junos OS supports QSFP-DD 400G DR4.
The module includes a one-year limited warranty covering defects and compatibility assurance. Technical support is available via our dedicated helpdesk.
No. The QSFP-DD 400G DR4 is designed for native 400 Gbps links. For breakout, use a QSFP-DD to four SFP-DD breakout cable assembly.
Use lint-free wipes and isopropyl alcohol to clean the fiber end-faces. Always cap unused ports to prevent dust and maintain optimal optical performance.
Standard stock items ship within 2–3 business days. For bulk or custom orders, lead times may extend up to two weeks depending on inventory levels.
