Abstract: The embodiments described herein are directed to a fiber optic cable and a fiber optic adapter housing. The cable comprises a connector body that houses a plurality of fiber portions. The connector body has a face comprising a plurality of rows of apertures for exposing respective ends of the fiber portions. Each aperture of a particular row are diagonally offset from nearest aperture(s) of an adjacent row. The housing comprises first slots having a first orientation and opposing second slots having a second orientation. The first slots are configured for the insertion of cables having the first orientation, and the second slots are configured for the insertion of cables having the second orientation. Such a configuration enables a shuffle function, where a device coupled to a cable inserted into a first slot is communicatively coupled to other devices each connected to a respective cable inserted into a respective second slot.

Abstract: Embodiments of a telemetry device and methods to convert a binary floating point number to a compressed number is described herein. The binary floating point number may comprise a mantissa and an exponent. The telemetry device may determine a first number based on a product of the exponent and a constant, wherein the constant may be proportional to a logarithm of the number two. The telemetry device may determine a second number using one or more bits of the mantissa as an index into a predetermined lookup table. Values of the lookup table may be proportional to logarithms of candidate mantissa values. The telemetry device may determine the compressed number based on rounding of a sum. The sum may include the first and second numbers. The rounding may be based on a predetermined step size.

Abstract: A computer system and method for transmitting LAN signals over transport systems. LAN signals are generated in any client LAN compliant interface. A transceiver receives the client LAN signal in the LAN format. The client LAN signals are not converted to a SONET transmission format at any time before reaching the transceiver. The transceiver then converts the client LAN signal to an internal electrical LAN signal before re-clocking the internal electrical LAN signal. The re-clocked internal electrical LAN signal is then re-modulated into a second LAN signal. The second LAN signal is then transmitted to a transport system.

Abstract: Embodiments of digital high-speed bi-phase modulator and method for bi-phase modulation are generally described herein. In some embodiments, the digital high-speed bi-phase modulator comprises a high-speed digital divider, a high-speed digital multiplexer, and matched signal paths provided between the divider and the multiplexer. The high-speed digital divider is configured to receive a carrier signal and generate complementary output signals. The high-speed digital multiplexer is configured to switch between the complementary output signals and generate a bi-phase modulated output at a carrier frequency (fc) modulated with a bi-phase code. The bi-phase code may be provided to control inputs of the multiplexer.

Abstract: The invention provides for optical circulators which redirect light from port to port sequentially in one direction used to separate traffic in a bidirectional optical fiber transmission system. The invention provides for using two optical circulators in each span of bidirectional fiber so that the OSC channel can be transmitted in one direction opposite to the WDM channels. The invention also provides for a gigabit Ethernet path between chassis which is utilized for control traffic and customer traffic. The invention is placed in a non-critical region of the optical spectrum and is independent of all other chassis equipment. The invention also provides the advantage in alternate embodiments of providing the option of a second counter propagating WDM channel being transmitted along with the OSC to provide additional system capacity. The invention also provides the advantage in an alternate embodiment of allowing the OSC to be amplified through a raman source without the need of complete system retrofit.

Abstract: A computer system and method for transmitting 10 Gigabit Ethernet (10GE) LAN signals over transport systems. Standard 10GE LAN signals are generated in any client IEEE 802.3 10GE LAN compliant interface. A transceiver receives the client 10GE LAN signal in the LAN format. The client 10GE LAN signals are not converted to a SONET transmission format at any time before reaching the transceiver. The transceiver then converts the client 10GE LAN signal to an internal electrical 10GE LAN signal before re-clocking the internal electrical LAN signal. The re-clocked internal electrical 10GE LAN signal is then re-modulated into a second 10GE LAN signal. The second 10GE LAN signal is then transmitted to a transport system.
