Verkkokaapeli BlueOptics JG329A-BL QSFP 4xSFP+ InfiniBand 1 m musta

The BlueOptics JG329A-BL QSFP 4xSFP+ InfiniBand 1m Black is a 1-metre fibre optic cable designed for connecting QSFP ports to four SFP+ ports in high-density networking and data centre environments. This male-to-male assembly provides a compact solution for splitting a single QSFP interface into four independent 10Gb/s links using InfiniBand or SFP+ compatible devices. The cable features a durable outer jacket in black with nickel-plated connector housings for mechanical resilience and consistent signal transmission.

Advantages

The cable supports high-speed data transmission by enabling QSFP-to-4xSFP+ breakout connectivity, reducing the need for additional transceivers or adapters. Its 1 m length offers a balance between flexibility and signal integrity in short-reach rack-to-rack or intra-rack connections. The robust construction and nickel-plated connectors improve durability and reduce connector wear, while the compact design simplifies cable routing in crowded equipment racks.

Suitable for

• Breaking out a QSFP port into four SFP+ links in data centres
• High-performance computing and InfiniBand clusters
• Rack-to-rack or within-rack short-reach connections up to 1 metre
• Environments requiring reliable 10GbE or InfiniBand links

Key specifications

• Cable length: 1 m
• Connector 1: QSFP (male)
• Connector 2: 4 × SFP+ (male)
• Typical use: QSFP to 4×SFP+ breakout for InfiniBand or 10Gb/s links
• Colour: Black with nickel-plated connector housings
• Weight: approximately 0.25 kg

How to use

Connect the QSFP end of the BlueOptics JG329A-BL to the QSFP port on the switch or host adapter, then insert the required SFP+ connectors into the target devices or ports. Ensure both ends are fully seated and that the equipment is powered down or hot-swap capable according to the device manufacturer’s guidance before insertion or removal. Verify link status LEDs and device configuration to confirm the breakout lanes are recognised and operating at the expected link speeds.

Recommendations

For optimal performance, use this 1 m breakout cable for short-reach connections within racks or between adjacent racks. Avoid tight bends and excessive strain on the cable; maintain recommended bend radii specified by the equipment vendor. Confirm compatibility of QSFP and SFP+ ports for InfiniBand or Ethernet modes on your switches and adapters before deployment.
