Table 10-10. OC-3 Rate OLIU Mixes — Maximum Link Budgets for SM Fiber (dB)
NOTE:
The maximum link budget is not always symmetrical. A transmitter/receiver
pair may have one maximum link budget in one direction and another in the
opposite direction. For example, a 21G/21G-U (low power) OLIU
transmitting to a 22F OLIU has a maximum SM link budget of 18.6 dB. In
the opposite direction, though, a 22F OLIU transmitting to a 21G/21G-U
(low power) OLIU has a maximum SM link budget of 15.0 dB. Be careful of
this asymmetry when planning and engineering a link having mixed OLIUs.
Note also that 21D/21D-U and 22D-U OLIUs will not operate when
transmitting into single-mode fiber.

The LAA10 FT-2000 OC-3 Optical Interface has the same optical loss budget as the
22G-U and therefore should follow the same optical mixing rules.
