Signal and Lane Configuration
The listed modulation format is 4x 25G-NRZ to 2x 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.
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
At 100m (328ft), QSFP28 to 2x QSFP28-100G-AOC-100M328FT should be planned as an extended equipment-room connection rather than a short in-rack jumper. Mark the complete vertical and horizontal route before installation, including every manager the cable will actually pass through. Support the integrated optical cable and both optical engines along that path and keep both ends free from pull loads. The next shorter verified assembly is QSFP28 to 2x QSFP28-100G-AOC-70M230FT at 70m (230ft), which is the better comparison when the managed route leaves substantial unused cable.
Position Within the Length Range
QSFP28 to 2x QSFP28-100G-AOC-100M328FT is the longest of 10 verified length options in this family. Compared with QSFP28 to 2x QSFP28-100G-AOC-70M230FT at 70m (230ft), it provides 30m 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.
Field Installation and Maintenance
Inspect the route and both connectors before installation, then support the cable without pulling on either connector housing. During maintenance, release the latch properly rather than using the cable as a handle. Keep protection on unused ends, and if the assembly is removed for later use, coil it loosely and record its part number so the same length can be returned to service. For this assembly, the minimum bend radius is 30mm; the stated power consumption is 2.2W (100G Per End)1.5W (50G Per End); the jacket material is OFNP.
Power and Thermal Planning
The rated power consumption is 2.2W (100G Per End)1.5W (50G 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 QSFP28 Electrical MSA, SFF-8636, SFF-8665. Confirm that the host firmware and port configuration support the same operating mode.
Breakout Port Mapping
The QSFP28 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.
Quality Assurance and Packaging
The cable and both connectors are inspected before a functional link test. Connector protection and bend-safe packing reduce handling damage during transport and storage. Customer or site labels can be added for field inventories, with different lengths separated to simplify issue and return of spare assemblies. Volume orders can include customer references on the labels and carton list.
Generic Compatibility and Factory Testing
A field-ready cable needs both correct identification and a stable operating link. Our pre-packing check therefore includes the connectors, host recognition and link behavior. For equipment with uncertain revision history, providing the host model and software release helps identify compatibility requirements before the assembly reaches the installation site. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.
Frequently Asked Questions
Is this an original equipment manufacturer cable?
No. It is manufactured by HT under our own manufacturer identity.
Does this order code cover multiple lengths?
No. QSFP28 to 2x QSFP28-100G-AOC-100M328FT refers here to 100m (328ft). 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.
Can excess cable be folded into a compact bundle?
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
Ordering Information
Request the cable by its exact part number and length, and state the equipment model if compatibility confirmation is needed. Site orders can list quantities by rack or installation team. Any requested label should retain the part number so a removed or spare cable can still be identified accurately. Keep QSFP28 to 2x QSFP28-100G-AOC-100M328FT associated with 100m (328ft) throughout the order and receiving record.
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. 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.
