ZX Mini-GBIC Specifications
Table 8 describes the specifications for the ZX mini-GBIC.
Long Range GBIC System Budgets
Measure cable plant losses with a 1550 nm light source and verify this to be within budget. When
calculating the maximum distance attainable using optical cable with a specified loss per kilometer (for
example 0.25 dB/km), Extreme Networks recommends that 3 dB of the total budget be reserved for
losses induced by cable splices, connectors, and operating margin. Figure 5 shows the total optical
system budget between long range GBICs in various end-to-end combinations (ZX, ZX Rev 03, LX70,
and LX100).
NOTE
The ZX mini-GBIC is equivalent to the ZX Rev 03 GBIC.
