A transparent window for a multiple socket includes a housing and a transparent plate. The support structure has an arcuate face with a length several times that of a tubular member of the superstructure so that the arcuate face provides support over a portion of the tubular member and so that the face mates with the tubular member. The invention also provides an elastomeric article having a first layer, the first layer comprising a natural or synthetic polymer; and a second layer bonded to the first layer, the second layer comprising a polymer composite fibrous coating. In the WDM passive optical network of the present invention, the ONUs each comprises a separate wavelength for communication in the upstream and the downstream directions.
