Abstract: Optical amplifiers are provided that have dispersion-compensating fiber that is pumped with an optical source to produce Raman gain. Removable modules of dispersion-compensating fiber, which may be separate from the Raman-pumped dispersion-compensating fiber, may be used to adjust the amount of dispersion compensation provided by a given amplifier. The Raman pump may be formed using fiber-Bragg-grating-stabilized diode lasers or other suitable pump sources. Two cross-polarized diode lasers may be used for the Raman pump to reduce the dependence of the Raman gain on the polarization of the pump. If desired, the dispersion-compensating fiber may be Raman pumped using a two-pass configuration in which pump light reflects off of a reflector to produce additional gain. The reflector may be a Faraday rotator to minimize polarization-dependent pump effects.

Abstract: An improved structure of a socket switch is provided which includes a body housing (11), a contact point housing (12), and a rear clamping member (13). The contact point housing (12) has an internal chamber (15) on a bottom end and a substantially triangularly shaped switch member (14) having a shaft member (21) extending from opposing sides is insertable within a groove (19) of the contact point housing (12). The triangularly contoured switch member (14) has a first apex which is located in the path of an insertable plug for rotation of a second apex member from a first position to a second position to allow switching from a second contact member and first contact members (17, 18) to a second position where a third contact member (16) is contacted by the second contact member (17). The contact point housing (12) has a pair of pintle hooks (20) which secure the rear clamping member within the internal chamber (15).
