Key Features
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 ear lier.
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 craft sperson.
