Abstract: An optical interconnection assembly for a Spine-and-Leaf network is disclosed. The optical interconnection assembly has Spine multi-fiber optical connectors and Leaf multi-fiber optical connectors. The Spine optical connectors of the interconnection assembly are optically connected to multi-fiber connectors of Spine switches via Spine patch cords. The leaf multi-fiber connectors are optically connected to Leaf multi-fiber connectors of Leaf switches via Leaf patch cords. An array of simplex fiber optic cables in said interconnection assembly serve to optically connect every Spine multi-fiber connector to every Leaf multi-fiber connector so that every Spine switch is optically connected to every Leaf switch. The optical interconnection assembly facilitates network Spine-and-Leaf interconnections and the ability to scale-out the network by installing additional assemblies, Leaf switches, and Spine switches.

Abstract: An apparatus having a plurality of multifiber connector interfaces, where some of these multifiber connector interfaces can connect to network equipment in a network using multifiber cables, has an internal mesh implemented in two tiers. The first is configured to rearrange and the second is configured to recombine individual fiber of the different fiber groups. The light path of each transmitter and receiver is matched in order to provide proper optical connections from transmitting to receiving fibers and complex arbitrary network topologies can be implemented with at least 1/N less point to point interconnections, where N=number of channels per multifiber connector interface.

Abstract: A multiport passive photonic light circuit chip has multiple waveguides written in at least two layers on a glass substrate. Some waveguides connect transmitting and receiving ports of an optical channel, some waveguides redirect a fraction of optical signals to some other receiving ports, and waveguides have circular cross-sectional shapes wherein a refractive index contrast is in the range of 0.2% to 2%.

Abstract: A patch cord for transmitting between a single mode fiber (SMF) and a multi-mode fiber (MMFs) has a MMF, SMF, and a photonic crystal fiber (PCF) with a hollow core placed between the SMF and MMF. A mode field diameter (MFD) of the PCF hollow core section is in the range of 16 to 19 microns, the length of the PCF is between 1 cm to 10 cm, the MMF has 50±2 microns core diameter, the SMF has a 6-9 microns core diameter, and the coupling between the PCF mode to the MMF fundamental mode is maximized.

Abstract: A low latency free-space optical data communication channel has at least one optical collimator for transmitting an optical communication signal in the form of a parallel beam across a free-space channel. The input of the collimator includes a connectorized optical fiber pigtail for connecting said collimator to a glass optical fiber carrying the signal to be transmitted across the free-space channel. The optical beam propagates in free space along the longitudinal axis of a raceway, which is at least partially enclosed. The second optical collimator located at the distant end of said raceway, is positioned to receive the free-space optical communication signal. The received signal is focused into a second optical fiber pigtail at the output side of the collimator, thereby resulting in a pigtailed free-space low latency optical channel link.

Abstract: Embodiments of the present invention provide an improved method of determining splice losses of mechanically terminated optical connectors in the field, without the need of terminating both sides of the fiber link. Embodiments of the present invention also provide means for improving the quality of mechanical splices as utilized in pre-polished fiber optic connectors for terminating single-mode and multimode optical fibers in the field.

Abstract: Methods for estimating the Effective Modal Bandwidth (EMB) of laser optimized Multimode Fiber (MMF) at a specified wavelength, λS, based on the measured EMB at a first reference measurement wavelength, λM. In these methods the Differential Mode Delay (DMD) of a MMF is measured and the Effective Modal Bandwidth (EMB) is computed at a first measurement wavelength. By extracting signal features such as centroids, peak power, pulse widths, and skews, as described in this disclosure, the EMB can be estimated at a second specified wavelength with different degrees of accuracy. The first method estimates the EMB at the second specified wavelength based on measurements at the reference wavelength. The second method predicts if the EMB at the second specified wavelength is equal or greater than a specified bandwidth limit.

Abstract: An expanded beam connector has a MOST ferrule; a fiber to be retained within the MOST ferrule; and, a collimating lens abutting the fiber for expanding the optical beam of the fiber wherein the lens and fiber are in alignment to a common optic axis. In one embodiment, the collimating lens can have a conical cutout configured to aid in aligning the fiber to the common optic axis. In another embodiment, the collimating lens can have a semi-cylindrical tab protruding from the rear with a V-groove configured to interact with a flexible feature on the interior of the ferrule to align the fiber to the common optic axis.
