Claim 12:
13. A pluggable network interface module, comprising:
a split-shell housing running a first length from a first end to a second end, wherein the second end comprises an open electrical interconnection end for the pluggable network interface module, the split-shell housing comprising:
a first shell portion extending the first length and comprising a first cavity running along a portion of the first length; and
a second shell portion extending the first length and comprising a second cavity running along a portion of the first length, wherein the first shell portion is joined to the second shell portion, and wherein the first cavity and the second cavity together form a receiving cavity for the split-shell housing;

a circuit substrate disposed at least partially within the receiving cavity, wherein the circuit substrate extends outside of the receiving cavity a second length from the second end of the split-shell housing to an end of the circuit substrate, wherein the circuit substrate comprises a first notch disposed in a first side of the circuit substrate along the second length and a second notch disposed in a second side of the circuit substrate along the second length;
a first shield portion disposed on a first width side of the split-shell housing and extending a shield length from the second end of the split-shell housing along a portion of the second length, wherein the shield length is less than the second length, the first shield portion comprising a first protrusion that extends into the first notch of the circuit substrate in a direction from the first width side toward a center of the circuit substrate; and
a second shield portion disposed on a second width side of the split-shell housing and extending the shield length from the second end of the split-shell housing, the second shield portion comprising a second protrusion that extends into the second notch of the circuit substrate in a direction from the second width side toward the center of the circuit substrate;
wherein a plurality of electrical contacts are disposed on an end portion of the circuit substrate that extends beyond the first shield portion and the second shield portion along the second length, wherein a portion of the first side of the circuit substrate extending along the second length past the shield length is exposed and uncovered by the first shield portion, wherein the first protrusion follows a shape of the first notch, wherein the second protrusion follows a shape of the second notch, wherein the first protrusion is offset from the circuit substrate providing a first airflow gap between the first shield portion and the first notch, and wherein the second protrusion is offset from the circuit substrate providing a second airflow gap between the second shield portion and the second notch.
