Extreme Networks 40GB-C015-QSFP Compatible 40G QSFP+ Passive Copper Cable, 1.5m (5ft)
For buyers working from an equipment parts list, 40GB-C015-QSFP identifies more than a connector style. It refers here to a 1.5m (5ft) DAC cable for Extreme Networks hosts, supporting 40G operation with QSFP+ to QSFP+. The sections below separate the OEM cross-reference, physical specification and HT factory checks for straightforward purchasing review.

Cable Construction and Routing
This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 33.5mm. 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 SFF-8436, QSFP+ MSA and IEEE 802.3ba. Confirm that the host firmware and port configuration support the same operating mode.
Passive Copper Operation
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.
Length Selection and Installation Planning
The additional half metre beyond a one-metre assembly gives 40GB-C015-QSFP useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.
Position Within the Length Range
40GB-C015-QSFP occupies the middle of this family between 10312 at 1m (3ft) and 40GB-C02-QSFP at 2m (7ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.
Procurement and Port-Mapping Review
A useful purchase order should identify the host platform, the expected OEM code and the exact cable length as separate pieces of information. This prevents a physically similar assembly from being substituted when the port identification or reach is different. For mixed-length installations, prepare one order line per part number and reconcile each delivered cable with its intended pair of ports. For this assembly, the listed conductor specification is 30AWG; the minimum bend radius is 33.5mm; the jacket material is PVC (OFNR).
Extreme Networks Compatibility and Factory Testing
Our procurement-oriented compatibility check begins with the OEM reference and ends with a live host link. We record the physical length separately from the identification configuration, so the cable supplied for this page remains the stated version rather than a generic length substitute. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.
Ordering Information
For a clear bill of materials, quote the OEM reference, HT part number, length and quantity on the same line. Add the switch or server model and software release when a pre-order review is required; project labels can repeat those details for receiving and installation teams. This page’s fixed configuration is 1.5m (5ft); another length must be quoted under its corresponding part number.
Quality Assurance and Packaging
Before packing, the assembly is checked for connector condition, identification and link operation. Cables for multi-line orders can be labelled and grouped by part number, making it easier to match each length to the procurement record without opening every protective bag. Standard protective packing is used by default, with project documentation arranged when requested.
Frequently Asked Questions
Is this an original Extreme Networks cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies Extreme Networks 40GB-C015-QSFP.
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.
Shipping and Lead Time
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.
