41. Later, Enitel added a 16x10 Gbit / s wavelength-division multiplexing system. 42. The sharing of physical channels using multiplexing often gives very large reductions in costs. 43. With TCP multiplexing , the situation is different. 44. It is a new technology for multiplexing . 45. PDH created larger numbers of channels by multiplexing the standard Europeans 30 channel TDM frames. 46. The multiplexing of multiple digital signals is much simpler to the multiplexing of analog signals. 47. The multiplexing of multiple digital signals is much simpler to the multiplexing of analog signals. 48. In addition to improvements in these multiplexing systems, improved modulation techniques are being used. 49. One technology, spatial multiplexing , gained importance for its bandwidth conservation and power efficiency. 50. It is used in Frequency division multiplexing .
