Known transceivers and transmitters for Dense Wavelength Division Multiplexing (DWDM) systems are typically formed from separately sourced components by a Network Equipment Manufacturer (NEM). Alternatively, transceivers or transmitters are formed as separate modules from separately sourced components by the NEM. Consequently, the NEM has to build the transmitters or transceivers. This construction is difficult, because known optical packages for housing optoelectronic components, such as laser diodes, comprise a fibre “pigtail” through which electromagnetic radiation leaves the optical package. The present invention overcomes this problem by providing a DWDM module apparatus (2) that comprises an optical package (10) for housing optoelectronic components, the optical package (10) comprising a first part of a coupling (12) attached thereto. The coupling is arranged to receive a ferrule connector, thereby facilitating connection of optical fibres to the transmitter or transceiver by means of a patch cord.
A module apparatus for a Dense Wavelength Division Multiplexing (DWDM) communications system, the apparatus comprising:
An apparatus as claimed in any one of the preceding claims, wherein the optical connector maintains a fixed spatial relationship with respect to the housing.
An apparatus as claimed in any one of the preceding claims, further comprising an electrical connector.
An apparatus as claimed in any one of the preceding claims, wherein the housing is formed so as to dissipate heat.
A DWDM optical package for housing optoelectronic components, the package comprising:
A use of a package in a DWDM system, the package comprising a housing for containing a source of electromagnetic radiation and having an optical connector coupled to the exterior of the housing.
A use of a module apparatus in a DWDM system, the module apparatus comprising an optical package for housing optoelectronic components, the optical package being disposed within a housing and including a source of electromagnetic radiation;
