An electronic-component connector forms a secure detachable connection and is packaged in a small space even when the electronic component is a module that is linked to an optical waveguide, and transmits and receives a signal such as an optical signal via the transfer member. The invention thus relates to the plants, seeds and tissue cultures of the variety 980003, and to methods for producing a corn plant produced by crossing a corn plant of variety 980003 with itself or with another corn plant, such as a plant of another variety. The cracking of an underlying layer may also be prevented by providing a slit in a direction parallel to the space between two adjacent metal line patterns at a sufficient distance from the space between the two adjacent metal line patterns. A sealing arrangement between the valve and body is also described. The chromatic dispersion-compensating optical fibre in the S-band has a wavelength corresponding to the global chromatic dispersion minimum, which is situated outside the spectral band in use, that is to say outside the S-band. In a second embodiment, the needle has a cryogen supply tube and cryogen supply.
