Use this 70m (230ft) AOC cable for hosts expecting Generic QSFP-DD to 8x 25G SFP28-200G-AOC-70M230FT and a 200G direct-attached interface. The assembly uses QSFP-DD to 8x 25G SFP28; lane, protocol and breakout considerations are documented alongside the verified table. Every alternative length remains a separate order code with its own technical page.

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.
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include QSFP-DD MSA V5.0,SFP28 MSA,CMIS V4.0,SFF-8472. Confirm that the host firmware and port configuration support the same operating mode.
The QSFP-DD to 8x 25G SFP28 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.
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.
Measure twice before deploying this 70m (230ft) cable: once along the planned route and again after accounting for service access. The objective is adequate reach without a concealed surplus. Support the integrated optical cable and both optical engines, preserve front-panel clearance and check that nearby power cords or sharp hardware cannot damage the jacket. The next shorter verified assembly is QSFP-DD to 8x 25G SFP28-200G-AOC-50M164FT at 50m (164ft), which is the better comparison when the managed route leaves substantial unused cable.
QSFP-DD to 8x 25G SFP28-200G-AOC-70M230FT is the longest of 12 verified length options in this family. Compared with QSFP-DD to 8x 25G SFP28-200G-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.
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 QSFP-DD <4W,SFP28 <1W.
The rated power consumption is QSFP-DD <4W,SFP28 <1W. 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.
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.
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. Keep QSFP-DD to 8x 25G SFP28-200G-AOC-70M230FT associated with 70m (230ft) throughout the order and receiving record.
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. Where supported by the host, receive activity and diagnostic indications are reviewed together with the established link.
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.
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. Volume orders can include customer references on the labels and carton list.
No. It is manufactured by HT under our own manufacturer identity.
Protect both connector ends, keep the cable in a loose bend-safe coil and retain its part-number label so the length and compatibility identity remain traceable.
Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.
No. QSFP-DD to 8x 25G SFP28-200G-AOC-70M230FT refers here to 70m (230ft). Every other verified length has a separate part number and page in the length list.
