Modular transceiver and accessory system for use in an optical network

A device, the device being suitable for use as a part of a network, the network including at least one transmission fiber, the device comprising:

• a body, the body including a first connector means;
• a first module, the first module being decoupleable from the body, the first module including a receiver means for receiving optical data and a transmitter means for transmitting optical data, the first module further including a second connector means and a first connection means, the first connection means being arranged to be coupled with the transmission fiber, the second connector means being arranged to be coupled with the first connector means, wherein when the first module is coupled to the body through the first connector means and the second connector means, the first module is arranged to communicate with the body, wherein the first module is arranged to support a first transmissions range;
• and
• a second module that is arranged to substantially improve on the first transmissions range, the second module being arranged to interface with the first module through the body, wherein the second module is decoupleable from the body.

A device, the device being suitable for use on a network, the device comprising:

• a body;
• a transceiver module, the transceiver module being arranged to be removably coupled to the body, the transceiver module further being arranged to transmit and to receive data through the network, the transceiver module still further being arranged to transmit and to receive data through the body, wherein the transceiver module supports relatively short range transmissions;
• and
• an accessory module, the accessory module being arranged to be removably coupled to the body, the accessory module further being arranged to transmit and to receive data through both the network and the transceiver module, wherein the accessory module cooperates with the transceiver module to support at least intermediate range transmissions.
