4. Inter-channel Skew is dened for the condition of equal amplitude, zero ps skew input signals. Input power at –10 dBm.
5. Rise and Fall Times are measured between the 20% and 80% levels using a 500 MHz square wave signal.
6. The Signal Detect output will change from logic “0” (Low) to “1” (High) within the specied assert time for a step transition in optical input
power from the de-asserted condition to the specied asserted optical power level on all 12 channels.
7. The Signal Detect output will change from logic “1” (High) to “0” (Low) within the specied de-assert time for a step transition in optical input
power from the specied asserted optical power level to the de-asserted condition on any 1 channel.

Notes:
1. The specied optical output power, measured at the output of a short test cable, will be compliant with IEC 60825-1 Amendment 2, Class
1 Accessible Emission Limits, AEL, and the output power of the module without an attached cable will be compliant with the IEC 60825-1
Amendment 2, Class 1M AEL. See discussion in the Regulatory Compliance section.
2. These are unltered 20-80% value measured with optical-electrical converter with 12 GHz bandwidth. To increase accuracy of measurement
owning to laser overshoot and ringing, a ltered rise/fall time measurement is adopted with a 2.5Gbps (1.875 GHz bandwidth) 4th Bessel
Thompson lter. A max spec of 150 ps for unltered waveform is equivalent to a max spec 242 ps for ltered waveform.
3. Inter-channel Skew is dened for the condition of equal amplitude, zero ps skew input signals.
4. Deterministic Jitter (DJ) is dened as the combination of Duty Cycle Distortion (Pulse-Width Distortion) and Data Dependent Jitter. Determin-
istic Jitter is measured at the 50% signal threshold level using a 2.5 GBd K28.5, or equivalent, test pattern with zero skew between the dier-
ential data input signals.
5. Total Jitter (TJ) includes Deterministic Jitter and Random Jitter (RJ). Total Jitter is specied at a BER of 10
-12
for the same 2.5 GBd test pattern
as for DJ.

Notes:
1. Sensitivity is dened as the OMA necessary to produce a BER of 10

Bit Sequence of length 2
7
– 1 (PRBS), or equivalent, test pattern. For this parameter, input power is equivalent to that provided by an ideal
source, i.e., a source with RIN and switching attributes that do not degrade the sensitivity measurement. All channels not under test are oper-
ating receiving data with an average input power up to 6 dB above P
IN MIN
.
2. Saturation is dened as the OMA that produces at the center of the output swing a receiver output eye width less than 120 ps where BER <
10
-12

7
–1 (PRBS), or equivalent, test pattern.
3. Stressed receiver sensitivity is dened as the average input power necessary to produce a BER < 10
-12
at the center of the Baud interval using
a 2.5 GBd Pseudo Random Bit Sequence of length 2
7
– 1 (PRBS), or equivalent, test pattern. For this parameter, input power is conditioned
with 2.5 dB Inter-Symbol Interference, ISI, (min), 120 ps Total Jitter, TJ (min). All channels not under test are operating receiving data with an
average input power up to 6 dB above P
IN MIN
.
4. Stressed receiver eye opening is dened as the receiver output eye width where BER < 10
-12
at the center of the output swing using a 2.5 GBd
Pseudo Random Bit Sequence of length 2
7
– 1 (PRBS), or equivalent, test pattern. For this parameter, input power is an average input optical
power of –10.4 dBm and conditioned with 1.2 dB ISI (min), 120 ps TJ (min), All channels not under test are operating receiving data with an
average input power up to 6 dB above P
IN MIN
.
5. Return loss is dened as the ratio, in dB, of the received optical power to the optical power reected back down the ber.
6. Signal Detect assertion requires all optical inputs to exhibit a minimum -15 dBm OMA. All channels not under test are operating with PRBS 7
serial encoded patterns, asynchronous with the channel under test, and an average input power up to 6 dB higher than P
IN MIN.
