## Summary description

The Helos 7.5m OM3 fibre optic cable features LC and ST connectors, a core diameter of 50 µm, and supports full duplex communication. Ideal for high-speed data transmission, this cable ensures reliable performance in networking applications. Its OM3 rating allows for efficient bandwidth usage, making it suitable for data centers and enterprise networks.

## Long description

The Helos 7.5m OM3 fibre optic cable with LC and ST connectors is designed for high-speed full duplex data transmission over multimode fibre. With a 50 µm core diameter and OM3 grading, the cable supports short- to medium-range connections where increased bandwidth and modal performance are required. The combination of LC and ST connectors provides interoperability between equipment using small-form-factor duplex ports and legacy or field-termination ST ports, making the cable useful in mixed-equipment environments.
Advantages
The OM3 multimode rating enables improved bandwidth and modal performance compared with lower-grade multimode fibres, supporting higher data rates at typical multimode distances. The 50 µm core diameter is compatible with common multimode transceivers, while the LC connector offers compact duplex interfacing and the ST connector provides a durable bayonet-style connection. The 7.5 m length gives flexibility for rack-to-rack or equipment-to-equipment cabling without excessive slack.
Suitable for
 Data centre interconnects between switches, servers and patch panels
 Enterprise LAN links requiring multimode OM3 performance
 Upgrading mixed-connector installations where LC and ST interfaces coexist
 Short- to medium-reach optical links supporting full duplex communication
Key specifications
 Fiber type: OM3 multimode fibre
 Core diameter: 50 µm
 Length: 7.5 m
 Connector A: LC (duplex)
 Connector B: ST
 Transmission mode: full duplex
 Typical application: high-speed multimode links
How to use
Identify the LC and ST ports on the devices to be connected. Ensure both link endpoints are powered down or follow hot-plugging guidelines of the equipment. Insert the LC duplex plug into the corresponding LC receptacle, taking care to align and engage the latch. Insert the ST connector into the ST port and rotate the bayonet sleeve to secure the connection. Route the cable to avoid tight bends and mechanical strain; maintain the manufacturer’s minimum bend radius for multimode fibre during installation. After connection, verify link status and run diagnostics or link tests as required by the network equipment.
Usage recommendations
Use this OM3 50 µm cable for intra-rack or adjacent rack connections where multimode transceivers are specified. Avoid kinking or exceeding the bend radius, protect connectors with dust caps when not in use, and keep connector end-faces clean to maintain signal integrity. Confirm transceiver compatibility with OM3 multimode fibre and full duplex operation before deployment.
