Signal and Lane Configuration
The listed modulation format is QSFP56-4x 50G-PAM4 QSFP28-4x 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.
Breakout Port Mapping
The QSFP56 to 2x 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.
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
The 20m (66ft) reach of QSFP56 to 2x QSFP28-200G-AOC-20M66FT is useful only when the managed pathway requires it; straight-line distance between ports is not a sufficient measurement. Check the route around rack rails, cable managers and maintenance clearances, then protect the integrated optical cable and both optical engines from tight bends and unsupported spans. Within this family, QSFP56 to 2x QSFP28-200G-AOC-15M49FT is shorter at 15m (49ft), while QSFP56 to 2x QSFP28-200G-AOC-25M82FT is the next longer choice at 25m (82ft); comparing those two boundaries helps avoid both tension and unnecessary slack.
Position Within the Length Range
QSFP56 to 2x QSFP28-200G-AOC-20M66FT occupies the middle of this family between QSFP56 to 2x QSFP28-200G-AOC-15M49FT at 15m (49ft) and QSFP56 to 2x QSFP28-200G-AOC-25M82FT at 25m (82ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.
Project Documentation and Cable Identification
Large deployments are easier to audit when the order code, physical length and endpoint record agree. Keep the OEM reference in the compatibility document and use the HT part number on the packing list. Where several lengths arrive together, labels and carton groups can be arranged by rack or port plan so installers do not have to identify cables by appearance alone. For this assembly, the minimum bend radius is 30mm; the stated power consumption is 5.5W（QSFP56 End）5.5W（QSFP28 Per End）; the jacket material is OFNP.
Power and Thermal Planning
The rated power consumption is 5.5W（QSFP56 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.
Cable Construction and Routing
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.
Network and Protocol Considerations
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include IEEE 802.3cd-100GAUI-2, IEEE802.3bm-CAUI-4, IEEE 802.3cd, SFF-8661, SFP-8636, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.
Generic Compatibility and Factory Testing
Factory verification links the compatibility identity to the exact physical assembly described on this page. Identification, connector condition and live link behavior are checked before packing. Customers can submit equipment and firmware details with the project documentation for a more specific pre-order compatibility review. The check includes receive activity and diagnostic indications, followed by a final inspection of both ends.
Frequently Asked Questions
Is this an original equipment manufacturer cable?
No. It is manufactured by HT under our own manufacturer identity.
Can different brands be connected with the same assembly?
Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.
Does this order code cover multiple lengths?
No. QSFP56 to 2x QSFP28-200G-AOC-20M66FT refers here to 20m (66ft). Every other verified length has a separate part number and page in the length list.
Are separate transceivers or patch leads required?
No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.
Ordering Information
Use the listed HT part number for ordering and retain the OEM reference as the host-compatibility cross-reference. Send quantities by length, along with any rack-based packing or label instructions. If the project has mixed equipment, include the host model for each group rather than relying only on the aggregate cable rate. This page’s fixed configuration is 20m (66ft); 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.
Quality Assurance and Packaging
Inspection and link testing are completed before the cable enters its protective packaging. Project orders can be packed and labelled by length, rack or customer reference, with packing documentation that makes received quantities straightforward to reconcile against the installation schedule. Neutral packaging and customer-specific packing documentation are available on request.
