Juniper Networks QDD-4X100G-AOC-2M Compatible 400G QSFP-DD 8 x 50G PAM4 to 4 x 100G QSFP28 4 x 25G NRZ Active Optical Breakout Cable, 2m (7ft)

The HT-manufactured QDD-4X100G-AOC-2M compatible cable provides 400G connectivity for Juniper Networks equipment. This 2m (7ft) version is a factory-terminated active optical link with the optical engines and fiber integrated into the assembly, with an exact part number and length that can be matched directly to the equipment requirement.

Juniper platform documentation distinguishes straight QSFP28 DAC or AOC connections from DACBO and AOCBO breakout operation. On channelized systems, the host port must be configured for the required breakout mode. Match this HT compatible cable to the exact Juniper part number and the intended platform configuration.

The listed modulation format is QSFP-DD-8x 50G-PAM4QSFP28-4x 25G-NRZ. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.

The rated power consumption is 10W (QSFP-DD End)5.5W (QSFP28 Per End). Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

This assembly uses OFNP jacket, minimum bend radius 30mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include QSFP-DD MSA, SFF-8661, IEEE802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, CMIS 4.0, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP-DD to 4x QSFP28 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.

QDD-4X100G-AOC-2M provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

QDD-4X100G-AOC-2M occupies the middle of this family between QDD-4X100G-AOC-1M at 1m (3ft) and QDD-4X100G-AOC-3M at 3m (10ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The HT cable carries the compatibility configuration associated with QDD-4X100G-AOC-2M, while its mechanical assembly remains the fixed 2m (7ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Juniper Networks software can request a pre-order check.

Quote HT part number QDD-4X100G-AOC-2M with the required quantity. The 2m (7ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, QDD-4X100G-AOC-2M and the 2m (7ft) length for easier inventory control.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
