QK737A Hpe Premier Flex Lc Lc Om4 2 Fiber 50m Cable Multi Mode

The QK737A HPE Premier Flex LC/LC Multi-mode OM4 2 Fiber 50m Cable is a specialized, ultra-long optical interconnect designed for large-scale data center architectures. Spanning 50 meters (approximately 164 feet), this cable is engineered for "End-of-Row" to "Core" switching or for connecting high-speed storage arrays across expansive data halls.

As part of the HPE Premier Flex series, it features bend-insensitive fiber (BIF) technology, which is essential for maintaining signal integrity over long distances where cables must navigate multiple turns, tight conduits, and congested overhead trays.

At 50 meters, standard multi-mode fibers often suffer from "macro-bending" losses that can lead to intermittent link drops or high bit-error rates. The QK737A mitigates these risks by utilizing a unique internal structure that keeps light tightly confined to the core, even under physical stress. This makes it a critical component for organizations deploying 10Gb, 40Gb, or 100Gb Ethernet over significant physical spans.

• OM4 Laser-Optimized Performance: Rated for 850nm VCSEL transmissions, this cable supports 10GbE up to 400m and 40Gb/100GbE up to 100m, ensuring it can handle the most demanding bandwidth requirements.
• Premier Flex Bend-Insensitivity: Features a specialized refractive index profile that prevents light leakage during sharp bends. This allows for up to 10 times less signal attenuation compared to standard OM4 cables, which is vital for the reliability of a 50-meter run.
• High-Precision LC Connectors: Equipped with industry-standard duplex LC-to-LC connectors and high-grade ceramic ferrules, the QK737A ensures ultra-low insertion loss and stable optical alignment.
• LSZH Safety Jacket: The signature blue jacket is composed of Low Smoke Zero Halogen (LSZH) materials, complying with international fire safety standards for data center plenums and high-occupancy buildings.

Yes. Under the OM4 standard, 100Gb Ethernet (SR4) is officially supported up to 100 meters. The QK737A provides a high-quality 50m path that is well within the operational limits for 100G speeds.

Absolutely. It is fully backward compatible with OM3 transceivers and patch panels. While the distance limits will revert to OM3 standards if mixed with older fiber, you will still benefit from the superior "Premier Flex" physical durability.

While the Premier Flex technology makes this cable much tougher than standard fiber, you should still avoid exceeding the minimum bend radius (typically 30mm for Premier Flex). Use Velcro ties rather than plastic zip ties to prevent crushing the jacket.

• Quality Assurance: Every QK737A cable is 100% optically tested for insertion loss and return loss before shipment. A test report is included to guarantee enterprise-level reliability over the full 50-meter span.
• Protective Packaging: Due to its length, the cable is carefully coiled and secured in high-impact, anti-static packaging. All LC connectors are fitted with protective dust caps to keep the polished ceramic ferrules clean.
• Worldwide Delivery: We provide global shipping with expedited options available for urgent data center expansions. All components are fully compliant with RoHS, REACH, and WEEE environmental standards.
