Abstract: An optical transmitter of a subscriber optical interface and an optical receiver of a laser transceiver node can be designed to a frequency of data that is formatted according to a predetermined network protocol, that is encoded with a predetermined coding scheme, and that is transmitted according to a predetermined data transmit timing scheme. The frequency of data is an occupied frequency of a protocol when the data comprises a maximum number of like bits permitted by the protocol. An optical transmitter and optical receiver can be designed to a lowest occupied frequency of data that is encoded with 8B/10B encoding, and that is propagated upstream according to time division multiple access (TDMA). In this way, upstream optical communications can be maximized for speed.

Abstract: An enclosure for facilitating and protecting splices or connections between communication transmission mediums can include a housing having a first port and a drop port. The first port can allow a distribution cable containing a transmission medium to enter the housing. The drop port can allow another transmission medium to enter the housing, and it can allow a transmission medium to be added or removed without disturbing existing transmission mediums or connections in the housing. A drop plug can be provided to seal the drop port. The enclosure can also include a cover plate having a gasket coupled to its perimeter and being removable with the cover plate. Strain relief for the transmission mediums entering the enclosure can also be provided. Two-stage strain relief and single-stage strain relief can be provided for the transmission mediums entering through the first port and the drop port, respectively.

Abstract: An optical fiber network can include an outdoor bandwidth transforming node that can be positioned in close proximity to the subscribers of an optical fiber network. The outdoor bandwidth transforming node does not require active cooling and heating devices that control the temperature surrounding the bandwidth transforming node. The bandwidth transforming node can adjust a subscriber's bandwidth on a subscription basis or on an as-needed basis. The bandwidth transforming node can also offer data bandwidth to the subscriber in preassigned increments. Additionally, the bandwidth transforming node lends itself to efficient upgrading that can be performed entirely on the network side. The bandwidth transforming node can also provide high speed symmetrical data transmission. Further, the bandwidth transforming node can increase upstream and downstream bandwidth and transmission speed by propagating data signals at different wavelengths.

The laser transceiver node can also provide high speed symmetrical data transmission. Further, the laser transceiver node can utilize off the shelf hardware to generate optical signals such as Fabry-Perot (F-P) laser transmitters, distributed feed back lasers (DFB), or vertical cavity surface emitting lasers (VCSELs).
