An entry module assembly comprising: an entry module plate (68, 74) defining a plurality of apertures, each aperture configured to receive a cable there through; and a plurality of seals coupled to the entry module plate (68, 74), each seal extending through an aperture of the entry module plate (68, 74), each seal configured to provide a substantially fluid-resistant seal between a cable extending through the seal and the seal, and between the seal and the aperture in the entry module plate (68, 74), each seal comprising: a first seal section defining a first internal cylindrical surface defining a first internal diameter configured to provide a substantially fluid-resistant seal between the first internal cylindrical surface and an external surface of a cable; and a second seal section coupled to the first seal section and defining a second internal cylindrical surface defining a second internal diameter configured to provide a substantially fluid-resistant seal between the second internal cylindrical surface and an external surface of a cable, wherein the first internal diameter and the second internal diameter differ from one another; wherein each seal further comprises a flange section coupled to the first seal section opposite the second seal section, the flange section defining an internal flange opening and an external flange portion projecting outwardly, wherein the external flange portion defines a cross-section comprising a first flange seal surface and a second flange seal surface opposite the first flange seal surface, characterised in that the first flange seal surface and the second flange seal surface are configured such that a first flange seal surface of a first seal and a second flange seal surface of a second seal abut one another at a seal interface providing a substantially fluid-resistant seal between the first flange seal surface of the first seal and the second flange seal surface of the second seal. an entry module plate (68, 74) defining a plurality of apertures, each aperture configured to receive a cable there through; and a plurality of seals coupled to the entry module plate (68, 74), each seal extending through an aperture of the entry module plate (68, 74), each seal configured to provide a substantially fluid-resistant seal between a cable extending through the seal and the seal, and between the seal and the aperture in the entry module plate (68, 74), each seal comprising: a first seal section defining a first internal cylindrical surface defining a first internal diameter configured to provide a substantially fluid-resistant seal between the first internal cylindrical surface and an external surface of a cable; and a second seal section coupled to the first seal section and defining a second internal cylindrical surface defining a second internal diameter configured to provide a substantially fluid-resistant seal between the second internal cylindrical surface and an external surface of a cable, wherein the first internal diameter and the second internal diameter differ from one another; a first seal section defining a first internal cylindrical surface defining a first internal diameter configured to provide a substantially fluid-resistant seal between the first internal cylindrical surface and an external surface of a cable; and a second seal section coupled to the first seal section and defining a second internal cylindrical surface defining a second internal diameter configured to provide a substantially fluid-resistant seal between the second internal cylindrical surface and an external surface of a cable, wherein the first internal diameter and the second internal diameter differ from one another; wherein each seal further comprises a flange section coupled to the first seal section opposite the second seal section, the flange section defining an internal flange opening and an external flange portion projecting outwardly, wherein the external flange portion defines a cross-section comprising a first flange seal surface and a second flange seal surface opposite the first flange seal surface, characterised in that the first flange seal surface and the second flange seal surface are configured such that a first flange seal surface of a first seal and a second flange seal surface of a second seal abut one another at a seal interface providing a substantially fluid-resistant seal between the first flange seal surface of the first seal and the second flange seal surface of the second seal.
