Product Overview

HYTOPTODEVICE 1M QSFP+ DAC Breakout Cable acts as a direct drop-in replacement for Brocade part 40G-QSFP-4SFP-C-0101. This passive fan-out twinax cable complies with SFF-8436 and SFF-8431 MSA standards, converting a single 40G QSFP+ port into four separate 10G SFP+ Ethernet channels. It consumes zero power and supports hot swap for live storage chassis maintenance.
We maintain stable inventory of this QSFP+ DAC Breakout Cable for buyers, wholesalers and IT integrators deploying Brocade storage and Ethernet switches. Every cable is preloaded with Brocade-matched EEPROM signatures to eliminate unsupported transceiver warnings on Fabric OS switches. Bulk procurement, sampling and custom OEM private labeling are available for distributors, SAN system builders and enterprise storage contractors.

Usage Guidelines & Best Practices

  • Mandatory Port Breakout Configuration: Ensure the host QSFP+ port supports channelization. Enable breakout mode (4x10G) via the switch CLI before connecting the cable.

  • Cabling Requirements: Do not exceed the minimum 21mm bend radius, avoid sharp folding, heavy extrusion or long-term tension on the cable assembly.

  • Port Installation Standard: Do not mix this breakout DAC with straight QSFP+ to QSFP+ DAC configuration.

  • Hot‑swap rule:Never pull or tug directly on the individual breakout legs. Always use the integrated pull-tab or bale latch when inserting or removing connectors.

  • Testing & Storage: Run sample validation on target hardware before large bulk deployment; store spare cables in dry, dust‑free and anti‑static packaging.
  • Operating Environment: 0‑70℃, indoor cabinet deployment only.

For detailed operation instructions, please refer to the User Guide.

The Core Feature

1. Near-Zero Power Draw, Cooler Dense Racks

This passive 40G QSFP+ DAC breakout cable draws only around 0.5 W — a tiny fraction of active copper and AOC alternatives — minimizing heat output and fan load in dense racks, while splitting one 40G QSFP+ port into four independent 10G SFP+ links with minimal latency for short-reach connections within a rack or between adjacent racks.

FAQ

Q1: Which Fabric OS firmware versions support port breakout for this Brocade compatible QSFP+ DAC Breakout Cable? A: It runs reliably on Fabric OS v7.4, v8.x and newer stable releases. HYTOPTODEVICE validates each batch for Brocade SAN hardware to reduce deployment risk for Brocade SAN partners placing stock orders.

Q2: Can this QSFP+ DAC Breakout Cable work for native Fibre Channel breakout on Brocade SAN directors? A: This copper breakout DAC is built for 40G Ethernet / FCoE, it does not support pure Fibre Channel breakout. Confirm port mode as Ethernet before purchase for Brocade storage deployments.

Q3: Can Fabric OS DPort diagnostic test run normally on this stocked QSFP+ DAC Breakout Cable? A: Yes, the pre-coded EEPROM allows DPort testing for link quality verification. This built-in diagnostic function helps storage contractors quickly validate links during SAN commissioning.

Q4: Can I get customized serial number marking on this QSFP+ DAC Breakout Cable for Brocade SAN tender traceability? A: Yes, HYTOPTODEVICE supports custom serial marking for bulk orders. Unique serial labels simplify asset tracking for system integrators handling large Brocade storage projects.

Q5: Will Fabric OS raise persistent error logs if mixed with Brocade original SFP+ optics on the same chassis? A: No, DAC and optical transceivers operate independently per logical port. Once breakout mode is committed correctly, mixed media will not trigger continuous fault alarms on Brocade switches.

Q6: Is this QSFP+ DAC Breakout Cable suitable for Brocade FCoE gateway links connecting to virtualized storage servers? A: Yes, passive copper media reliably transports FCoE lossless traffic. Many storage resellers purchase this breakout cable to expand low-cost 10G FCoE access ports in Brocade fabrics.

Q7: Will breakout port settings stay intact after Fabric OS firmware upgrade on Brocade 6520 switches? A: Breakout configurations are saved persistently in the switch database. Major firmware migration may require re-verification for stocked QSFP+ DAC Breakout Cable units after upgrade.

Q8: What lead time applies to bulk orders of this QSFP+ DAC Breakout Cable for overseas Brocade SAN distributors? A: Ready stock orders normally ship within 3–5 working days. HYTOPTODEVICE maintains local inventory and offers expedited shipping for urgent Brocade storage project procurement.

Q9: Does this QSFP+ DAC Breakout Cable support Brocade Virtual Fabric logical SAN partitioning? A: Yes, passive copper does not interfere with VSAN and Virtual Fabric partitioning rules. Each 10G breakout lane can be assigned independently to different logical storage networks.

Q10: What should I check first if one breakout SFP+ link drops during Brocade FCoE traffic transmission? A: First validate Fabric OS breakout enable command and reseat the SFP+ connector. Lane outages are usually caused by incomplete port configuration or loose insertion on newly purchased cables.

Q11: Are there special humidity limits when wholesalers keep this QSFP+ DAC Breakout Cable in warehouse inventory? A: Keep inventory under 10–60% RH indoor dry conditions. High-purity copper used by HYTOPTODEVICE prevents oxidation and preserves electrical performance for multi-year resale stock.

Q12: Do Brocade 6510 switches require an extra license key to activate 40G-to-4x10G breakout mode? A: Breakout capability is a base hardware function on Brocade 6510 Ethernet ports and does not require premium licensing. Buyers should cross-check hardware port specs before ordering.

Q13: Can the four SFP+ branches of this QSFP+ DAC Breakout Cable plug into 10G SFP+ NICs on VMware ESXi hosts? A: Yes, the SFP+ legs interoperate with standard 10G SFP+ server adapters. It is a cost-effective cabling choice for Brocade FCoE fabrics connected to hypervisor servers.

Q14: What quality documents can HYTOPTODEVICE supply for enterprise SAN bidding projects? A: We can provide batch TDR test reports, RoHS and REACH compliance certificates. These documents help wholesalers qualify for government and enterprise Brocade storage tender projects.

Q15: Can I reflash the EEPROM of this QSFP+ DAC Breakout Cable for reuse on other vendor switches after Brocade SAN decommissioning? A: Yes, HYTOPTODEVICE provides EEPROM reprogramming service. This helps resellers repurpose stocked breakout cables for multi-vendor data center fabrics and improve inventory ROI.
