Abstract: A fiber optic transmission cable fiber protector includes a splice tube positioned over the ends of a pair of fiber optic cables having an outer capillary tube containing at least one optical fiber within an inner capillary tube. The optical fiber protector includes a pair of optical fiber strain relief mechanism positioned near the ends of the optical fibers; the strain relief mechanisms are captured within a heat sink tube that is inserted into each end of the outer capillary tubes. The splice tube is welded to the outer capillary tubes. Heat generated by the welding process dissipated by the heat sink and gases generated during the welding process are vented through a hole in the outer capillary tube into the optical fiber splice area. In an alternate embodiment a weld coupling is welded to each end of the splice tube and is further welded to the outer capillary tubes. A sealing mechanism is positioned on the inner capillary tubes within the outer capillary tubes forming a seal therebetween. A splice protection sleeve is positioned over the optical fiber splice area to protect the splice during assembly of the protector. In an alternative embodiment an optical fiber protector assembly includes a carrier tube disposed onto the inner capillary tube and an optical fiber strain relief mechanism positioned within the carrier tube near the end of the optical fiber capturing the fiber therein in a strain relieved condition.

Abstract: An optical channel monitor is provided that sequentially or selectively filters an optical channel(s) 11 of light from a (WDM) optical input signal 12 and senses predetermined parameters of the each filtered optical signal (e.g., channel power, channel presence, signal-noise-ratio). The OCM 10 is a free-space optical device that includes a collimator assembly 15, a diffraction grating 20 and a mirror 22. A launch pigtail emits into free space the input signal through the collimator assembly 15 and onto the diffraction grating 20, which separates spatially each of the optical channels 11 of the collimated light, and reflects the separated channels of light onto the mirror 22. A λ/4 plate 26 is disposed between the mirror 22 and the diffraction grating 20. The mirror reflects the separated light back through the λ/4 plate 26 to the diffraction grating 20, which reflects the channels of light back through the collimating lens 18. The lens 18 focuses each separated channel of light (λ1-λN) at a different focal point in space. One of the optical channels 11 is focused onto a receive pigtail 28, which then propagates to a photodetector 30. A pivoting mechanism 34 pivots the diffraction grating 20 or mirror 22 about a pivot point 36 to sequentially or selectively focus each optical channel 11 to the receive pigtail 28. A position sensor 42 detects the displacement of the diffraction grating 24 or mirror.
