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.

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.

Interoperability and Configuration Checks

Check three layers before deployment: the host must accept the cable identification, the port must support the stated aggregate rate, and the lane configuration must match the attached interfaces. On breakout hardware, also confirm channelization and the mapping of every branch. These checks are particularly important when similar-looking ports operate at different speeds or under different firmware settings. 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.

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.

Ordering Information

Specify the OEM part number and fixed length, then provide the intended host configuration if the link uses channelized or breakout ports. Separate part numbers should be used for separate lengths. This gives the compatibility review enough information to check both the physical assembly and the intended operating mode. This page’s fixed configuration is 50m (164ft); another length must be quoted under its corresponding part number.

Generic Compatibility and Factory Testing

The verification process combines digital identification with a live link test and diagnostic observation. Host model, hardware revision and software release are useful inputs because qualification behavior can change between platform generations; those details allow platform-specific requirements to be reviewed before the cable is packed. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.

Quality Assurance and Packaging

Functional inspection covers identification, link establishment and the condition of both connector assemblies. The cable is then protected against dust and connector damage and packed without sharp bends. Labels can include the customer reference and host-platform note when requested for a controlled deployment. Neutral packaging and customer-specific packing documentation are available on request.
