TIA TSB-172-A PDF

This TSB reviews some techniques and technologies that can be applied to address high-rate transmission for multimode fiber systems. These techniques include serial and multiplexed transmission, dispersion compensation, and forward error correction technologies. Multi-level coding is examined as an alternative to the commonly used binary code.

Possible key specifications appear in Annex B for a laser-optimized 50/125-μm multimode fiber that provides wider wavelength spectrum relative to the specifications in TIA-492AAAC. This is an example of what can be achieved to enhance the performance of systems using wavelength division multiplexing.
