BlueOptics JNP-100G-2X50G-2M-BL InfiniBand fibre optic cable QSFP28 2m Male/Male

The BlueOptics JNP-100G-2X50G-2M-BL InfiniBand fibre optic cable QSFP28 2m Male/Male is a 2‑metre high-speed connection designed for short-range links in data centers and rack environments. It provides a QSFP28-to-QSFP28 interface for 100G data paths and supports InfiniBand and Ethernet-based protocols where QSFP28 connectivity is required. The cable is intended for direct rack-to-rack or within-rack connections and offers a compact, vendor-compatible solution for networks that require reliable 100G links over a 2 m distance.

Advantages

This QSFP28 cable delivers a standardized electrical interface compatible with 100GBase-CR4 and InfiniBand applications, enabling high throughput with low latency for short connections. The 2 m length and male-to-male QSFP28 termination simplify integration into existing switch, router and storage hardware that accept QSFP28 direct attach solutions. The product is manufactured to industry MSA guidelines and uses quality components to provide long service life and consistent performance in dense rack deployments.

Suitable for

• Short-range 100G links between switches, routers and network appliances
• Top-of-rack and adjacent-rack connections in data centers
• InfiniBand fabrics and high-performance computing interconnects
• Storage area network uplinks and server interconnects requiring QSFP28

Key specifications

• Connector type: QSFP28 to QSFP28 (male/male)
• Cable length: 2 metres
• Supported link speeds: up to 100 Gbit/s (100GBase-CR4 / equivalent)
• Application: InfiniBand, Ethernet, FCoE and Fibre Channel over supported hardware
• Cable type: direct attach twinax / passive connection for short distances
• Wire gauge example: 30 AWG (design for low attenuation on short runs)
• Form factor: compact QSFP28 suitable for dense rack installations

How to use

Install the cable by inserting each QSFP28 plug into the corresponding QSFP28 port on compatible switches, routers or storage devices. Ensure both devices support passive QSFP28 direct‑attach connections and the targeted transmission protocol (Ethernet/InfiniBand/FCoE) at 100 Gbit/s. Route the 2 m cable to avoid sharp bends and mechanical strain; secure it within the rack to prevent port stress. After insertion, verify link status on the connected devices and confirm negotiated speed and protocol parameters in the hardware management interface.

Recommendations

For best results, use the cable for short, high-bandwidth connections within racks or between adjacent racks. Confirm device compatibility with QSFP28 passive direct attach cables and test the link in your environment before deploying in critical paths. Avoid tight bends and excessive pulling force; store unused cables coiled with a gentle radius.
