An optical transceiver device has an optical transceiver component, an O/E conversion substrate and a switch control substrate. The optical transceiver component is connected to the first, second optical fiber network equipments for the transmission of optical signal, respectively. The O/E conversion substrate is electrically connected to an in-line equipment at a first location for transmission of electrical signal, and may convert the received optical signal into the electrical signal or convert the received electrical signal into the optical signal. The switch control substrate is electrically connected with an optical switching switch and is connected with the in-line equipment at a second location to receive a control signal for the optical switch from the in-line equipment such that the optical switching switch operates at an normal mode or an bypass mode to guarantee normal network communication of the first, second optical network equipment.

Optical transceiver device

An optical transmitter for converting and coupling an information-containing electrical signal with an optical fiber having an electrical input for coupling with an external electrical cable or information system device having a plurality of parallel data lines, a modulator for converting between an information-containing electrical signal on each data line and a multi-level digital pulse amplitude modulated signal corresponding to the binary electrical signal; and a signal timing circuit coupled to said modulator for aligning the data signal to a predetermined clock signal. The transmitter is preferably wavelength division multiplexed, using an electro-optical subassembly coupled to each respective timer circuit for converting between the information-containing electrical signal and a modulated optical signal corresponding to the electrical signal at a predetermined wavelength. The transceiver is preferably implemented in a pluggable standardized form factor.

Optical transceiver for 100 Gigabit/second transmission

A method is provided of managing traffic in a network. The method comprises applying (S5) an indication to a packet being sent through the network, the indication being selected in dependence upon a level of traffic determined (S3) for a subscriber associated with the packet and representing a per-hop behaviour to be applied subsequently to the packet. The indication is applied so as to manage at least to some extent traffic associated with the subscriber.
