  2. Actual Power Optical Power Level Minimum optical power required by the receiver 0.1µW -40 dBm Source output optical power 1 mW 0 dBm Total operating budget (optical power) 40 SNR voltage ratio required in the receiver is 36 dB. The equivalent optical power ratio is* 18 dB Remaining optical power for link 22 dB Link optical power losses: Cable 15 dB Connectors 3 dB Couplings 2 dB Total 20 dB Excess Budget 2 dB Typical Optical Link Power Budget:

  4. Specifications For Fiber Optic Networks Here is a listing of many fiber optic LANs and links available in the last 20 years, with basic operational specs. NA = Not Applicable NS = Not Specified Most LANs and links not specified to run on SM fiber have media converters available to allow them to run on SM fiber.
