## Summary description

The BlueOptics JL489A-BL is a 5 m InfiniBand/fibre optic cable featuring SFP28 connectors. It provides reliable data transmission and is designed for high-speed networking applications.

## Long description

The BlueOptics JL489A-BL InfiniBand/fibre optic cable is a 5 m connection cable with SFP28 male-to-male connectors, designed for high-speed networking and short-distance interconnects in racks and adjacent racks. It supports 25GBase-CR class transmission and is suitable for electrical direct-attach twinax applications where SFP28 interfaces are used. The construction follows MSA guidelines and is intended for use with hardware that accepts SFP28 passive DAC-style cabling.
Advantages
This 5 m SFP28 cable provides reliable 25 Gbit/s data transfer over short distances with low latency and low power consumption. The passive twinax design eliminates active components in the cable itself, reducing failure points and production cost while offering compatibility with platforms that support passive SFP28 DACs. Components and assembly are selected for long service life and consistent signal integrity.
Подходит для
Interconnects between switches and routers inside racks and across adjacent racks
Direct-attach connections for storage systems and server NICs with SFP28 ports
High-bandwidth applications using Ethernet, FCoE or InfiniBand up to 25 Gbit/s over 5 m
Key specifications
Connector type: SFP28 male — SFP28 male
Cable length: 5 metres
Nominal data rate: up to 25 Gbit/s
Cable type: passive twinax (direct attach)
Wire gauge: 30 AWG
Compliance: MSA-compatible mechanical and electrical characteristics
Typical power consumption: very low (passive cable, no active electronics)
How to use
Insert each SFP28 connector into the corresponding SFP28 port of the two devices to be linked, ensuring proper seating and latch engagement. Use the cable for short-distance links up to 5 m in data center racks or adjacent cabinets. Verify that both connected devices support passive SFP28 DACs and the intended protocol (25G Ethernet, FCoE, or InfiniBand) before deployment. For multi-vendor environments, confirm compatibility with the target switch or host firmware and port configuration.
Usage recommendations
Route the cable to avoid sharp bends and maintain the minimum bend radius specified by the hardware platform. Avoid placing the twinax cable next to high-power or noisy electrical sources for best signal integrity. For critical links, test the connection after installation and keep spare cables available for rapid replacement if required.
