Abstract:
The present invention discloses a method and system for transferring TDM services in GPON, the method includes the steps of: in the case of performing the GPON ranging process, buffering the uplink TDM service data received by an optical signal transceiver in an Input Buffer, reading out and transferring the uplink TDM service data buffered in an Output Buffer. The present invention eliminates the possible interruption of TDM services during the GPON ranging process by buffering the uplink services at the OLT and ONU/ONT side and relevant processes, and therefore realizes the TDM service transmission without any loss during the GPON system ranging process.

Abstract:
A heat dissipation device is provided in the present disclosure, where the heat dissipation device includes a hollow heat-sink base and a set of fluid tube. The fluid tube is inserted in the heat-sink base, and a cooling medium circulates in the fluid tube. The heat-sink base includes a heat absorption area configured to absorb heat. A cooling fluid, received in the heat-sink base, may be vaporized at the heat absorption area to absorb the heat taken by the heat absorption area, and condensed at a position that is inside the heat-sink base and away from the heat absorption area and on the fluid tube to release the absorbed heat.
Abstract:
Embodiments of the present disclosure disclose an optical cable and an optical cable system, where the optical cable includes an SZ-shaped optical cable skeleton and a plurality of optical fiber units. Skeleton slots is recessed in a periphery of the optical cable skeleton, and the plurality of optical fiber units is grouped and respectively disposed in the corresponding skeleton slots, thereby having the advantages of being easy to strip and draw, high reliability, and long lifetime. Moreover, the optical fiber does not need to be connected when being diverged on floors during installation, thereby reducing the fusion splicing/termination connection time, simplifying the optical cable wiring, greatly reducing deployment cost of an Optical Distribution Network (ODN), and speeding up the scale deployment of the FTTX ODN; in addition, interference among the optical fibers is avoided when the optical fibers are drawn, thereby increasing reliability of the optical fibers after installation.
Abstract:
This invention relates to a method for the reconstruction of a tissue-engineered human corneal endothelium. Human corneal endothelial cells are cultured in vitro to logarithmic growth phase using 20% calf bovine serum-containing DMEM/F12 medium. Trypsin is used to digest epithelial layer of the freeze-dried human amniotic membrane in order to produce denuded human amniotic membrane as scaffold carriers. The scaffold carriers are tiled on the bottom of culture plate wells until they are dried and completely adhered to the bottom of wells. Human corneal endothelial cells at logarithmic growth phase are re-suspended in DMEM/F12 medium containing type-IV collagen and 20% calf bovine serum. Human corneal endothelial cell suspension is subsequently inoculated to amniotic membrane scaffold carriers that are tiled on the bottom of wells in culture plate to launch in vitro culture as well as in vitro reconstruction of tissue-engineered human corneal endothelium. This invention is scientific and rational. The reconstructed tissue-engineered human corneal endothelium can be produced on large scale to satisfy the great demand of tissue-engineered human corneal endothelium in clinical cornea transplantation for primary corneal endotheliopathy therapy. Meanwhile, costs for in vitro reconstruction of tissue-engineered human corneal endothelium and clinical therapy are low.
