This letter introduces the design and preparation of a novel non-photonic crystal structured and bend-insensitive singlemode optical fiber.It numerically analyzes the trench waveguide structure of the fiber and obtains by using the PCVD process its sample with a MFD of 4.3μm at 1 310 nm and 5.4μm at 1 550 nm

and a splicing loss with G.652 Dfiber as low as0.15dB/2joints

satisfying the splicing requirements of common jumpers.When this sample is wound 10 turns with a bend radius of 2.5mm

its bending loss is optimized to 0.01 dB at 1 550 nm

satisfying any harsh FTTx application environment.Furthermore

it has the potential to replace copper cables as an ideal transmission medium in consumer electronics and to be applied in various photoelectronic devices.
