Cisco ONS 15216 EDFA2/EDFA2-A Operations Guide, R2.4
July 2004
Chapter 5 SNMP MIB Configuration
5.4.16 RtcDateAndTime
5.4.16 RtcDateAndTime
The cerent15216EdfaRtcDateAndTime table allows the user to set the date and time. When setting the
local time of day, set the time zone first, set the DST offset second, and set the local time last. Entries
must follow this format: “yyyy-m-d,h:m:s.s +h:m”. Following the space, the time zone is set as +/- hours
from Greenwich Mean Time (GMT) (also designated as universal coordinated time (UTC)) followed by
a colon and minutes ahead for daylight savings. For example, Pacific Daylight Time would be -8:60 and
Greenwich Mean Time would be +0:0.
cerent15216EdfaPumpStatus
InPowerdBm
Integer
(–999999 to
999999)
Read-only Optical input power to the pump, in
units of 0.01 dBm. For example, a
value of -753 is actually -7.53 dBm.
cerent15216EdfaPumpStatus
OutPowermW
Integer
(0 to 999999)
Read-only Optical output power of the pump, in
units of 0.01 mW. For example, a value
of 3497 is actually 34.97 mW.
cerent15216EdfaPumpStatus
OutPowerdBm
Integer
(–99999 to
99999)
Read-only Optical output power of the pump, in
units of 0.01 dBm. For example, a
value of 1542 is actually 15.42 dBm.
cerent15216EdfaPumpStatus
Gain
1
Integer
(–9999 to 9999)
Read-only The gain across the pump, in units of
0.1 dBm. For example, a value of 229
is actually 22.9 dBm.
cerent15216EdfaPumpStatus
ControlMode
constGainTemp
Comp(2),
constOutputPow
er(3),
constCurrent(4),
constPower(5),
idle(6)
Read-only Laser pump control mode.
cerent15216EdfaPumpStatus
ControlValue
Integer
(0 to 3000)
Read-only Laser pump control value. The units
depend on control mode:
constGainTempComp: 0.1 dB
ConstOutPower: 0.1 mW
constCurrent: 0.1 mA
constPower: 0.1 mW
For example, if the pump control mode
is constGainTempComp, then a value
of 229 is actually 22.9 dB.
1. In Constant Gain Temperature Compensated mode, the value of the cerent15216EdfaPumpStatusGain variable should always
be around 23 dB. This variable is the internal amplifier module gain. The cerent15216EdfaPumpStatusGain variable should
not be confused with the cerent15216EdfaConstGainOverallGain variable that is used to set the gain of the ONS 15216
EDFA2. The cerent15216EdfaPumpStatusGain is the value of the gain of the amplification module only, it does not take into
account the VOA (variable optical attenuator) attenuation. If you try to calculate the gain using the values of the
PumpStatusOutPowerdBm – PumpStatusInPowerdBm you will not get the exact PumpStatusGain value. A more complex
calculation is required to get the gain value. It needs to take ASE (amplified spontaneous emission) into account. This variable
will be more dominant when the input power to the amplifier is low.
