CHAPTER 3: HARDWARE
3.5 Transceiver optical power budget vs. link length
Optical Power Budget (OPB) is the available optical power for a fiber optic link to accommodate fiber cable losses plus
losses due to in-line connectors, splices, and optical switches. OPB also provides a margin for link aging and unplanned
losses due to cable plant reconfiguration and repair.
