Parameter Specifications
Maximum transmitter and dispersion
penalty 3.9 dB at 300 m
Transmitter characteristics
Root-mean-square spectral width 0.05 to 0.40 nm
Launch power – 7.3 to – 1.0 deciBels referenced to 1 milliwatt
(dBm)
Maximum average launch power of
OFF transmitter – 30 dBm
Minimum extinction ratio 3.0 dB
Maximum relative intensity noise
12
OMA
– 128 dB per Hertz (dB/Hz)
Maximum optical return loss tolerance – 12 dB
Receiver characteristics
Average receive power for BER 10
-12
– 9.9 to – 1.0 dBm
Maximum average receive power for
damage 0 dBm
Maximum receiver sensitivity in OMA – 11.1 dBm
Maximum receiver reflectance – 12 dB
Stressed receiver sensitivity in OMA – 7.5 dBm
Receiver electrical 3 dB upper cutoff
frequency 12.3 gigaHertz (GHz)
The stressed sensitivity values are for system level BER measurements, which include the
effects of clock and data recovery (CDR) circuits. Avaya recommends that you allocate at least
0.4 dB additional margin if you make component level measurements without the effect of CDR
circuits.
10GBASE-LRM SFP+ specifications
The 10GBASE-LRM SFP+ provides 10 GbE service at a wavelength of 1310 nm. This SFP+
can attain a reach of up to 220 m on 62.5
μ
m multimode fiber. This SFP+ provides built-in
electronic dispersion compensation.
The following table lists the transmitter and receiver specifications for the 10GBASE-LRM SFP
+. These parameters meet the IEEE 802.3aq-2006 standard. The part number of this SFP+ is
AA1403017-E6.
In this table, the OMA, average launch power, and peak power specifications apply at TP2,
after accounting for patch cord loss.
