Fiber optic patch cable BlueOptics SFP3131BU1MK 1 m G.657.A1 LC–LC 9 µm full duplex yellow

BlueOptics SFP3131BU1MK is a 1 m yellow fiber optic patch cable with laser‑optimized single‑mode G.657.A1 fiber (9/125 µm) and duplex LC/UPC to LC/UPC connectors. The cable is designed for full‑duplex transmission at typical telecom wavelengths (1310 nm / 1550 nm), features a flame‑retardant LSZH jacket and compact LC connectors for use in data centers, telecom racks and network equipment where space and bend performance matter.

Advantages

The patch cord provides low attenuation (specified 0.4 dB/km) and high return loss; connector polish options (UPC or 8° APC) allow further return‑loss optimization. Manufactured with branded fibers (e.g., Corning, Fujikura, YOFC) and high‑quality connectors (Amphenol, Diamond, Nissin Kasei, Reichle & De‑Massari) with zirconia ceramic ferrules, the assembly is rated for up to 1500 mating cycles. Every cable is tested with interferometer and OTDR and shipped with a measurement protocol for insertion loss and return loss. The product complies with Telcordia GR‑326‑Core and common industrial standards, and the LSZH jacket reduces toxic fumes and smoke in case of fire.

Suitable for

• Patch panels and fiber distribution frames in data centers
• Interconnecting optical transceivers and network equipment
• Tight‑bend or space‑constrained installations using G.657.A1 fiber

How to use

Unpack the BlueOptics SFP3131BU1MK cable and route it between the two LC ports to be connected, avoiding sharp kinks. Insert each LC connector until the latch clicks to provide a secure connection. For confined pathways, use the cable’s bend‑insensitive properties to maintain minimum bend radius recommendations and avoid excess tension. Verify link performance using the included insertion loss and return loss measurement protocol or by testing with appropriate optical test equipment.

Usage recommendations

Store and install the cable away from mechanical stress and active heat sources. When connecting to transceivers or patch panels, keep connector end faces clean and inspect or clean them before mating to ensure error‑free transmission. For custom lengths or APC polish requirements, request options from the supplier.
