Cables Direct FB3M-LCST-030D 3m LC ST Aqua InfiniBand/Fibre Cable

Cables Direct FB3M-LCST-030D | 3m OM3 LC to ST Fibre Cable

The Cables Direct FB3M-LCST-030D InfiniBand/fibre optic cable 3 m LC ST Aqua colour is a 3-metre OM3 multi-mode patch lead designed for high-bandwidth network links. It features an LC connector on one end and an ST connector on the other, finished in a distinct aqua jacket. This cable is suited for data centre or office backbone connections where OM3 performance is required. The low smoke zero halogen (LSZH) jacket offers enhanced safety in confined spaces. Because it is full duplex, it supports simultaneous bidirectional data transfer. This makes it a practical choice for connecting switches, servers, or media converters with compatible LC and ST ports.

High-Bandwidth OM3 Performance for Shorter Runs

This OM3 cable supports 850 nm and 1300 nm wavelengths, offering higher bandwidth than older OM2 cables. In practice, this means it can handle 10 Gigabit Ethernet over typical intra-building distances. For example, it is ideal for connecting equipment racks within the same data hall. Because the core is 50 µm, it optimises light transmission for multi-mode applications. However, you should confirm the maximum distance required for your specific network speed.

LC to ST Hybrid Connectivity

The cable combines an LC connector with an ST connector, providing a hybrid link between modern and legacy equipment. LC connectors offer high port density, while ST connectors use a bayonet mount for secure attachment. So, this cable is useful when adapting between different patch panel types. Also, both connectors are male, meaning they plug directly into female ports on your devices. You must verify that your equipment has compatible LC and ST ports before purchasing.

Low Smoke Zero Halogen (LSZH) Safety

The aqua jacket is made from Low Smoke Zero Halogen (LSZH) material. This reduces the amount of toxic smoke released if the cable is exposed to fire, making it safer for use in enclosed spaces. For example, it is suitable for office ceilings or under-floor containment. However, it does not specify flame retardant ratings such as FRLSZH. Therefore, you should confirm compliance with local building regulations for your installation area.

Full Duplex Operation for Efficient Data Transfer

This cable is full duplex, allowing data to be sent and received simultaneously on separate fibre strands. This doubles the effective throughput compared to half-duplex connections. Because it uses two fibres within one jacket, it simplifies cable management. In practice, this supports cleaner installations in patch panels. Also, the 3 mm round cable diameter is flexible for tight routing. You should confirm that your network devices are configured for full duplex operation.

Precision Optical Specifications

The cable has an insertion loss of 0.3 dB and a return loss of 35 dB. These figures indicate minimal signal degradation over the 3-metre length. For example, low insertion loss is critical for maintaining link budget in multi-mode networks. However, these specs assume proper connector seating and cable integrity. You should verify that your testing equipment can measure these parameters if required for certification.

Frequently Asked Questions

Q: Is this cable compatible with InfiniBand networks?

A: Yes, it is listed as an InfiniBand/fibre optic cable, but confirm your InfiniBand switch ports use LC or ST multi-mode connectors.

Q: What is the difference between OM3 and OM2 cables?

A: OM3 offers higher bandwidth and supports longer distances for 10 Gigabit Ethernet compared to OM2, as stated in the product description.

Q: Can I use this cable outdoors?

A: The LSZH jacket is designed for indoor use; confirm outdoor-rated variants if needed, as this is not specified.

Q: Does this cable come with a warranty?

A: Covered by the standard Manufacturer Warranty. Confirm warranty length and region with Hardvance or the manufacturer.

Q: Is the aqua colour standard for OM3 cables?

A: Yes, aqua is the recognised colour code for OM3 multi-mode fibre, aiding quick identification in installations.
