BlueOptics SFP3232BU20MK InfiniBand Fibre Optic Cable 20 m SC Yellow

The BlueOptics SFP3232BU20MK InfiniBand Fibre Optic Cable 20 m SC Yellow is a 20‑metre duplex SC–SC fibre patch cord designed for high‑speed data transmission. It uses G.657.A1 singlemode fibre (E9/125 µm) with a 9 µm core diameter and supports full duplex communication at common wavelengths (1310 nm / 1550 nm). The cable is supplied in yellow with SC/UPC connectors on both ends and is jacketed with a flame‑retardant LSZH material for reduced smoke and no halogen release in the event of fire. Products are tested by interferometer and OTDR and include measured insertion loss and return loss values with each shipment.

Advantages

The SFP3232BU20MK offers low attenuation and low insertion loss suitable for long‑reach links, with typical attenuation performance around 0.4 dB/km for the specified fibre type. Polished SC/UPC connectors with zirconia ceramic ferrules provide stable optical alignment and reliability over repeated mating cycles. Use of industry‑grade singlemode fibres from established manufacturers and branded connector components ensures consistent optical performance. Compliance with common industry norms and the LSZH jacket improves safety and suitability for professional installations.

Key specifications

How to use

Connect each SC/UPC connector into the corresponding SC receptacle on the transceivers, patch panels or devices, ensuring correct polarity for transmit and receive channels. Route the cable to avoid sharp bends and mechanical strain; maintain the manufacturer’s recommended minimum bend radius for G.657.A1 fibre. If required, verify link performance with an optical power meter or OTDR after installation using the supplied measurement protocol.

Recommendations

Store and install the cable in a dry, dust‑free environment. Avoid excessive pulling force and repeated tight bends; secure the cable with gentle, non‑crimping cable management accessories. For critical links, use the provided test report to confirm insertion and return loss meet system requirements and choose the appropriate connector polish (UPC or APC) if higher return loss performance is needed.
