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.

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.

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

Longer assemblies require disciplined cable dressing. For QSFP28-DD to Duplex-LC-200G-AOC-70M230FT at 70m (230ft), use the intended managers rather than a diagonal route across the rack, and leave enough space to release each connector. Any service allowance should be loose and supported, with the integrated optical cable and both optical engines protected throughout the path. The next shorter verified assembly is QSFP28-DD to Duplex-LC-200G-AOC-50M164FT at 50m (164ft), which is the better comparison when the managed route leaves substantial unused cable.

Position Within the Length Range

QSFP28-DD to Duplex-LC-200G-AOC-70M230FT is the longest of 11 verified length options in this family. Compared with QSFP28-DD to Duplex-LC-200G-AOC-50M164FT at 50m (164ft), it provides 20m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

Data-Center Design and Airflow

Select the assembly by both reach and rack layout. A direct connection removes separate module-and-patch-cord interfaces, but it still needs a bend-safe pathway and clear connector access. Keep cable bundles from blocking front-panel airflow, account for the listed interface power where applicable and choose a length that supports maintenance without leaving an unmanaged coil. 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.

Quality Assurance and Packaging

Each cable receives connector inspection and a functional link check before it is coiled with bend-safe slack and packed. Protective materials shield the connector housings during transport. Rack or project labels are available to keep length, part number and installation destination aligned. Standard protective packing is used by default, with project documentation arranged when requested.

Ordering Information

Provide the OEM reference, HT part number, fixed length and quantity, together with the intended host interfaces. Rack-based quantities and packaging instructions can be included for larger deployments. Other lengths are separate products and should be entered on their own order lines. Keep QSFP28-DD to Duplex-LC-200G-AOC-70M230FT associated with 70m (230ft) throughout the order and receiving record.

Generic Compatibility and Factory Testing

Compatibility confirmation combines host identification with actual link establishment and diagnostic checks. The assembly is prepared for the stated OEM reference rather than selected only by connector shape. For a new data-center deployment, the equipment model, port mode and software release provide the most useful basis for a pre-order review. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.
