This QSFP28-DD to Duplex-LC-200G-AOC-70M230FT compatible cable gives project teams a defined 200G connection in 70m (230ft), with QSFP28-DD to Duplex-LC and Generic host compatibility. Rather than treating all lengths as interchangeable, the page keeps this order code separate and links the other verified lengths for accurate schedules, labels and delivery checks.

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.
Length Selection and Installation Planning
Choose QSFP28-DD to Duplex-LC-200G-AOC-70M230FT when the measured managed path justifies 70m (230ft), 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. 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.
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 ≤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.
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. QSFP28-DD to Duplex-LC-200G-AOC-70M230FT refers here to 70m (230ft). 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 70m (230ft); another length must be quoted under its corresponding part number.
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
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. Volume orders can include customer references on the labels and carton list.
