Note 1:
Operating conditions are as per Recommended Operating Conditions. Test pattern PRBS-23 at 2.5Gbps with
50/125
µ
m fiber, unless otherwise specified.
Sensitivity for a channel (as defined in IEEE 802.3z Gigabit Ethernet) is specified at a BER of 10
-12
using a fast rise/
fall time source with low RIN and Extinction Ratio not less than 6 dB. All channels not under test are receiving signals
with an average input power of 6 dB, or higher, above worst case sensitivity.
The stressed receiver sensitivity is measured using 2.4 dB Inter-Symbol Interference, ISI, (min), 33 ps Duty Cycle
Dependent Deterministic Jitter, DCD DJ (min) and 6 dB ER (ER Penalty = 2.2 dB). All channels not under test are
receiving signals with an average input power of 6 dB, or higher, above worst case sensitivity.
The stressed receiver eye opening represents the eye at TP4 as defined in IEEE 802.3z Gigabit Ethernet
Specification 38.5. The stressed receiver eye opening is measured using 2.4 dB ISI (min), 33 ps DCD DJ (min), 6 dB
ER (ER Penalty = 2.2 dB) and an average input optical power of –9.6 dBm (0.5 dB above Minimum Stressed
Receiver Sensitivity as defined in IEEE 802.3z Gigabit Ethernet Specification Section 38.5). All channels not under
test are receiving signals with an average input power of 6 dB, or higher, above worst case sensitivity.
Total Jitter, TJ, equals TP3 to TP4 as defined in IEEE 802.3z Gigabit Ethernet Specification 38.5. Total jitter is
specified at a BER of 10
-12
(TJ=DJ+RJ
rms
x 2Q, where Q=7 for BER 10
-12
and RJ=Random Jitter).

Note 7:
Deterministic jitter includes duty cycle distortion.
Electrical channel skew is measured with the input signals having equal amplitude and no input optical
channel skew.
All channels not under test are receiving signals with an average input power of 6 dB, or higher, above the channel
under test.
Return loss is the ratio between received optical power and optical power reflected back into the fiber.
