BlueOptics SP-CABLE-FS-QSFP+3-BL InfiniBand Fibre Optic Cable 3m Male/Male

The BlueOptics SP-CABLE-FS-QSFP+3-BL InfiniBand Fibre Optic Cable 3m Male/Male is a 3‑meter high‑speed connectivity cable with QSFP+ style connectors designed for short‑range links in data centers and high‑performance computing environments. It provides a reliable physical layer for 40G-class applications and low-latency data transfer when used with compatible InfiniBand or Ethernet hardware. The cable is intended for direct rack-to-rack or intra-rack connections where a compact QSFP+ interface and a fixed 3 m length are required.

Advantages

This fibre optic cable offers stable high-bandwidth transmission and low latency suitable for dense networking environments. Male-to-male QSFP+ connectors ensure straightforward mating with QSFP ports on switches, routers and storage systems. The 3 m length balances flexibility and signal integrity for short-range connections while minimizing excess cable management. The design follows industry connector conventions to maximize interoperability with devices that support QSFP+ style interfaces.

Suitable for

• Interconnecting switches and top-of-rack hardware in data centers
• High-performance computing clusters requiring low-latency links
• Storage area networks and server-to-switch links
• Short-range InfiniBand and 40G Ethernet connections within racks

Key specifications

• Cable type: multimode/mode determined by manufacturer deployment (fibre optic)
• Connector: QSFP+ style male to QSFP+ style male
• Length: 3 metres
• Intended data rates: up to 40 Gbps class applications (per supported protocol)
• Typical use: short-range rack and adjacent-rack connections

How to use

Identify compatible QSFP ports on your networking equipment and ensure devices support the intended InfiniBand or 40G Ethernet protocol. Align the QSFP+ connectors with the port guides and insert the connector until it seats securely; follow the host equipment vendor instructions for handling and port locking mechanisms. Route the cable to avoid sharp bends and mechanical stress, keeping bend radius within the manufacturer's recommendations. For removal, release any retention latch and pull straight out to avoid damaging the connector.

Recommendations

Use this 3 m QSFP+ fibre optic cable for short, high-throughput links inside racks or between adjacent racks. Store and handle the cable in clean conditions to avoid contamination of fibre endfaces, and inspect/clean connectors before insertion. Confirm compatibility with your hardware vendor's supported cable and protocol lists to ensure correct operation.
