1.3.3 Transient Suppression

Transients in the performance of optical amplifiers are inevitable whenever the number of signals, or the relative power of signals, changes. The ONS 15216 EDFA2 uses transient suppression to reduce the amount of time required by an amplifier to recover from a change. This indicates the suitability of the amplifier for add/drop applications like those described earlier.

1.3.4 Low Noise

Whenever there is gain in an optical system, noise also occurs. The predominant source of noise in EDFAs is amplified spontaneous emission (ASE). The ONS 15216 EDFA2 has a low noise figure of less than 7 dB at –5 dBm input.

1.3.5 SNMP MIBs

The ONS 15216 EDFA2 SNMP MIBs contain definitions of management information that allows network systems to be remotely monitored, configured, and controlled.

1.3.6 TL1

The ONS 15216 EDFA2 has a TL1 interface available to the network operator and craftsperson.
