H3C LSWM1QSTK2 Compatible 40G QSFP+ Passive Copper Cable, 5m (16ft)

For short, high-density connections, this DAC cable combines 40G performance with a fixed 5m (16ft) cable run. It corresponds to H3C LSWM1QSTK2 and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: LSWM1QSTK2HT Part Number: LSWM1QSTK2

Product Highlights

• Compatible alternative to H3C LSWM1QSTK2
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to QSFP+
• Fixed length and part number: 5m (16ft), LSWM1QSTK2
• Conductor specification: 26AWG
• Minimum bend radius: 40mm

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 40mm. 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.

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

The 5m (16ft) length gives LSWM1QSTK2 more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the DAC specification and host support must still match the intended link.

LSWM1QSTK2 is the longest of 3 verified length options in this family. Compared with LSWM1QSTK1 at 3m (10ft), it provides 2m 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.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include SFF-8436, QSFP+ MSA and IEEE 802.3ba. Confirm that the host firmware and port configuration support the same operating mode.

Compatibility is more than matching the QSFP+ to QSFP+ shape. This assembly is prepared for hosts expecting LSWM1QSTK2 and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

Quote HT part number LSWM1QSTK2 with the required quantity. The 5m (16ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
