Fiber optic patch cable CBO SFP3333BU3MK 3 m, 2× ST connectors, G.657.A1, yellow, single-mode

Fiber optic patch cable CBO SFP3333BU3MK is a 3 m single-mode jumper with two ST connectors and a yellow outer jacket. The cable uses G.657.A1 bend-insensitive fibre designed for indoor networking, telecommunications and data centre link applications where routing flexibility and low loss around bends are required. The compact ST terminations and single-mode performance make this patch lead suitable for standard optical links and interconnects in tight spaces.

Advantages

This single-mode patch cable provides bend-insensitive G.657.A1 fibre to reduce attenuation in tight routing situations, helping to maintain signal integrity in confined installations. ST connectors ensure straightforward push-and-twist mating and are widely supported in legacy and current networking equipment. The 3 m length covers typical rack-to-rack and equipment-to-patch-panel connections while the yellow jacket offers standardised colour coding for single-mode links and easy visual identification.

Key specifications

How to use

Ensure both ports to be connected are clean and compatible with ST terminations. Remove protective caps from the connectors, align the ST bayonet-style ferrule with the equipment socket, insert and twist to lock. Route the cable to avoid sharp bends beyond the recommended minimum bend radius for G.657.A1 fibre; secure with non-compressive cable ties or organisers to prevent kinks. If disconnecting, twist to unlock and pull straight out without bending the fibre sharply.

Recommendations

Regularly inspect and, if necessary, clean connector endfaces with approved fibre cleaning tools before mating. Avoid crushing or applying excessive tensile force to the cable; adhere to recommended bend radius guidelines for G.657.A1 fibre to preserve low-loss performance.
