Optical Loss Budget (Example 2)

1000BASE-ZX GBIC Pt max = 5 dBm Pt min = 0 dBm Pr max = -3 dBm Pr min = -23 dBm. Questions: Can you connect one GBIC to another with only a patchcord? How can you ensure that the fiber system does not exceed the maximum loss?. Optical Loss Budget (Example 2). Pt max 5 dBm.
