Specifications

Signal and Lane Configuration

The listed modulation format is 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.

Breakout Port Mapping

The QSFP28-DD to Duplex-LC 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.

Integrated Optical Assembly

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.

Length Selection and Installation Planning

Choose QSFP28-DD to Duplex-LC-200G-AOC-50M164FT when the measured managed path justifies 50m (164ft), not simply to leave a large spare coil. Additional reach can simplify adjacent-rack routing, yet unused cable still needs bend-safe storage and ventilation clearance. Keep identification visible so this extended version is not confused with shorter spares. Within this family, QSFP28-DD to Duplex-LC-200G-AOC-30M98FT is shorter at 30m (98ft), while QSFP28-DD to Duplex-LC-200G-AOC-70M230FT is the next longer choice at 70m (230ft); comparing those two boundaries helps avoid both tension and unnecessary slack.

Position Within the Length Range

QSFP28-DD to Duplex-LC-200G-AOC-50M164FT occupies the middle of this family between QSFP28-DD to Duplex-LC-200G-AOC-30M98FT at 30m (98ft) and QSFP28-DD to Duplex-LC-200G-AOC-70M230FT at 70m (230ft). It adds 20m over the shorter option for extra routing clearance, while the next longer version adds another 20m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Rack Layout and Service Access

Plan the managed route before removing the connector protection. The cable should reach both ports without tension while leaving enough space to release the latches and service adjacent interfaces. Support the run through the intended managers, keep the connector boots clear of sharp edges and avoid storing excess length in a tight coil behind warm exhaust air. For this assembly, the minimum bend radius is 30mm; the stated power consumption is ≤3.47W.

Power and Thermal Planning

The rated power consumption is ≤3.47W. 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.

Cable Construction and Routing

This assembly uses 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.

Network and Protocol Considerations

The intended application is Ethernet, 5G Front Haul. Listed interface and protocol references include QSFP-DD MSA CMIS 4.0, IEEE 802.3bs 200G-SR8, IEEE 802.3by 25G-SR. Confirm that the host firmware and port configuration support the same operating mode.

Quality Assurance and Packaging

The completed cable is inspected at both ends, functionally tested and coiled with bend-safe slack. Protective packaging keeps the latches and boots from taking impact, while optional project labels can identify the two endpoint locations for easier field service. Standard protective packing is used by default, with project documentation arranged when requested.

Generic Compatibility and Factory Testing

Compatibility is verified as part of a complete installation check: connector inspection, host identification and an operating link. The physical cable is evaluated together with the expected OEM identity, because a connector that fits is not sufficient evidence that the host will accept and operate the assembly correctly. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.

Frequently Asked Questions

Ordering Information

When requesting this assembly, include the exact part number and length together with the destination port types. For a rack installation, a simple port-to-port list helps us keep different lengths separate and allows any requested labels to correspond with the actual installation sequence. This page’s fixed configuration is 50m (164ft); another length must be quoted under its corresponding part number.

Shipping and Lead Time

Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. International express, air cargo and sea freight can be selected according to destination and carton volume; customer courier accounts and nominated forwarders are also accepted.
