Brocade 100G-Q28-Q28-C-01501 Compatible 100G QSFP28 4 x 25G NRZ Passive Copper Twinax Cable, 1.5m (5ft)

Use the 100G-Q28-Q28-C-01501 compatible assembly where a 100G connection is required between compatible ports. This page covers the 1.5m (5ft) version only, with its own HT part number, specifications and compatibility verification.

The listed modulation format is 4x 25G-NRZ to 4x 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.

The additional half metre beyond a one-metre assembly gives 100G-Q28-Q28-C-01501 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.

100G-Q28-Q28-C-01501 occupies the middle of this family between 100G-Q28-Q28-C-0101 at 1m (3ft) and 100G-Q28-Q28-C-0201 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.

The rated power consumption is ≤0.5W. 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.

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.

The intended application is 100G Ethernet. Listed interface and protocol references include QSFP28 MSA, SFF-8662, IEEE 802.3. Confirm that the host firmware and port configuration support the same operating mode.

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.

Each 100G-Q28-Q28-C-01501 compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Brocade platform should be included with the order.

When ordering, specify 100G-Q28-Q28-C-01501, cable length 1.5m (5ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
