Abstract: A boundary router is presented for exchanging packets between a first data communication network and a second data communication network via a long-haul optical fiber communication network. Each optical fiber employed in the optical fiber communication network has, for a given transmission distance and modulation rate, a maximum available bandwidth or transmission capacity. The router includes a first interface for transmitting and receiving, at a first line rate, packets to and from the first data communication network, and a second interface for transmitting and receiving, at a second line rate different from the first line rate, packets to and from the long haul optical fiber communication network. Advantageously, the second line rate is selected such that a greater amount of the maximum available bandwith of each optical fiber in the long haul optical fiber communication network is utilized than at the first line rate. The most efficent line rate for the optical links of a given long haul network may be lower or higher than the first line rate. Hence, to arrive at the second line rate, the router may be configured to either aggregate the packets received via the first interface with packets received via one or more additional interfaces or, alternatively, to separate a single stream of packets received via the first interface into plural streams, while maintaining the integrity of individual flows. These aggregating and separating operations are transparent to the network layer.

Abstract: A submarine fiber-optic cable joint is provided with a load-bearing casing (12) for use with unarmored fiber-optic cables (1, 2). The device includes first and second terminating socket assemblies (11) for terminating the strength members (6) of a first and second fiber-optic cable respectively (1, 2). The optical fibers (19) of the two cables are spliced together and are stored in a fiber storage tray (23) that slidably engages the terminating socket assemblies (11). A cylindrical steel casing (12) encloses the fiber storage tray (23) and is attached to the first and second terminating socket assemblies (11) by fasteners. By slidably engaging the terminating socket assemblies (11) while the terminating socket assemblies remain fixed with respect to the casing (12), the fiber storage tray (23) is non-load-bearing. Thus, when a load is placed on one of the cables connected to the cable joint, the load is transferred to the other cable through the steel casing (12). As a result, little or no load passes through the fiber storage tray (23).

Abstract: A method and apparatus (Fig. 3) is provided for transmitting an optical signal. The method includes the step of generating an optical signal that includes a plurality of optical channels, which are sequentially numbered from 1 to N from lowest to highest wavelength. A state-of-polarization of predetermined odd-numbered channels (TRANS. #1,#3,#N-1) is oriented to be substantially orthogonal to a state of polarization of predetermined even-numbered channels (TRANS. #2,#4,#N) by directing the predetermined odd-numbered channels and the predetermined even-numbered channels through orthogonally polarizing inputs of a polarization coupler (315). The odd-numbered channels and the even-numbered channels may be directed through first and second wavelength combiners (307-308), respectively, prior to orienting their states of polarization. The orthogonal relationship between the states of polarization of odd and even-numbered channels advantageously limits the four-wave mixing products that can be generated in the optical transmitter and the optical transmission path to which it is typically coupled.

Abstract: Disclosed is a redundant TTE optical transmission system architecture which eliminates system signal power loss due to protection elements and thus provides a system power budget comparable to non-redundant TTE systems. Further disclosed is a virtually non-failing optical amplifier (3a), for redundant and non-redundant optical systems, which allows for the simultaneous exploitation of the pump power from both sets of laser pumps (50) in a dual-pump configuration, thereby increasing the available system power margin.

Abstract: An apparatus for retaining and protecting spliced optical fibers that are part of cables that have ultra-high strength steel wires, in which the optical fibers are free to move within a sleeve inside of the wires. The apparatus includes a joint box having opposing longitudinal cable termination ends. The high-strength steel wires of each cable are attached to a respective cable termination end. At least one optical fiber from each cable extends through its respective cable termination end and is spliced together to form a continuous optical fiber. The fiber or fibers are splinted and potted at locations longitudinally spaced from the splice to form ferrules. A central portion or shelf of the joint box includes fiber retaining devices which take the form of ferrule retainer assemblies. The ferrule retainer assemblies have a trough that contains and restrains a respective ferrule. Tension forces applied to the fibers are transferred to joint box via the splint and the relationship between the ferrules and the ferrule retaining assemblies.

Abstract: An architecture for a database process that can process many large queries simultaneously without creating bottlenecks uses a separate database server process to act as the interface with the processes generating the database queries, and a database engine process to process the queries. The database server receives the query notifications and queues the query structure it then passes the query to the database engine when it becomes available. The present invention allows the database server to service small queries it receives, such as requests for configuration data which are critical, and allows a configuration of multiple database engines to service several large queries simultaneously. The database engine process does not actively receive requests from the database server. Rather, it requests work from the database as it becomes available employing a time-out mechanism when the database engine is idle. According to another aspect of the present invention, the database processes perform their own load balancing.

Abstract: A method for designing an optical system is disclosed. The optical system launches optical signals modulated with data into a fiber link having a property of inducing nonlinear distortion of the optical signals as a function of signal power of the optical signals and distance traversed in the fiber link. A Q-factor curve for the fiber link is determined as a function of the signal power. A signal power is preselected based on the Q-factor curve. The preselected signal power is associated with a set of channels. A coding gain is preselected based on the preselected signal power and a desired channel spacing for the set of channels.

Abstract: A high-powered optical pump (15) includes at least two sub-pumps (36, 37). Each sub-pump (36, 37) generates a light at different wavelengths. The outputs of the sub-pumps (36, 37) are coupled to a remote pump fiber (15). The resulting light transmitted on the remote pump fiber (15) results in a lower raman gain and raman noise spectral peak than that generated by existing single wavelength high-powered optical pumps at the same power level. Therefore, increased power can be transmitted on the remote pump fiber (15) in contrast to a single wavelength pump.

Abstract: A passive branching joint assembly includes a housing (20) for a fiber storage device (30). The housing (20) is attached at one end to an endplate (80, 120) which accommodates at least one terminal socket (100), and is attached at the other end to an endplate (80, 120) which accommodates at least two terminal sockets (100). Fiber optic cables (190) are attached at the terminating sockets (100) so that loads placed on the terminating sockets (100) are transferred through the endplates and housing (20), rather than to the fiber storage device.
