Cable Construction and Routing
This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 37.5mm. 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 40G InfiniBand 8x DDR, 4x QDR, 10G/40Gigabit Ethernet, Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.
Length Selection and Installation Planning
The 7m (23ft) reach of LSWM1QSTK7A 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 complete copper assembly and both connector housings from tight bends and unsupported spans. The next verified reach is LSWM1QSTK10A at 10m (33ft), but selecting it before measuring the route would introduce additional slack to support.
Position Within the Length Range
LSWM1QSTK7A is the shortest of 2 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is LSWM1QSTK10A at 10m (33ft), adding 3m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.
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 listed conductor specification is 26AWG; the minimum bend radius is 37.5mm; the jacket material is PVC (OFNR).
H3C 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. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.
Frequently Asked Questions
Is this an original H3C cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies H3C LSWM1QSTK7A.
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.
Will any matching connector operate at the same speed?
Not necessarily. Both hosts must support the stated rate, identification, lane mapping and any required breakout configuration; mechanical compatibility alone is insufficient.
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. Quantity and any labeling instructions should be attached specifically to LSWM1QSTK7A.
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.
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. Standard protective packing is used by default, with project documentation arranged when requested.
