H3C LSWM1QSTK0 Compatible 40G QSFP+ Passive Copper Cable, 1m (3ft)

The HT-manufactured LSWM1QSTK0 compatible cable provides 40G connectivity for H3C equipment. This 1m (3ft) version is a factory-terminated passive copper link without separate optical modules or patch cords, with an exact part number and length that can be matched directly to the equipment requirement.

OEM Part Number: LSWM1QSTK0HT Part Number: LSWM1QSTK0

Product Highlights

• Compatible alternative to H3C LSWM1QSTK0
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to QSFP+
• Fixed length and part number: 1m (3ft), LSWM1QSTK0
• Conductor specification: 30AWG
• Minimum bend radius: 35mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 35mm. 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.

At 1m (3ft), LSWM1QSTK0 is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

LSWM1QSTK0 is the shortest of 3 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 LSWM1QSTK1 at 3m (10ft), adding 2m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

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.

The assembly is configured for equipment that recognizes LSWM1QSTK0. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

Quote HT part number LSWM1QSTK0 with the required quantity. The 1m (3ft) 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.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, LSWM1QSTK0 and the 1m (3ft) length for easier inventory control.

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.
