Test Report For Moduletek QSFP-100G-SR4-C-G11 Optical Module

Moduletek has launched the QSFP-100G-SR4-C-G11 multimode optical module, which supports 100G Ethernet applications. Moduletek Laboratory conducted sample testing on this model to help users fully understand its key parameters and actual operating performance on network devices.

1. Product Description

The key parameters and physical appearance of the QSFP-100G-SR4-C-G11 module are as follows:

Table 1 Module Key Parameters

Physical Layer Interface	Maximum Transmission Distance (m)	Operating Temperature (℃)	Fiber Type	Fiber Interface Type	Wavelength (nm)	Transmit Optical Power @ Per Channel (dBm)	Received Optical Power @ Per Channel (dBm)	Maximum Power Consumption (W)
100GBASE-SR	100@OM4	0 ~ 70	MMF	MPO	850	-8.4 ~ 2.4	-10.3 ~ 2.4	2

2. Module On-Board Identification Test

This module supports a 100G data rate. After inserting the sample module into a Cisco Nexus9000 C93180YC-EX switch, the module established a normal link with the port indicator lit up. Both the module identification information and DOM data displayed normally. Detailed test data are shown in Table 2:

3. Key Parameter Testing of the Module

In Moduletek Laboratory, the key parameters of the sample module were tested at a module case temperature of 70℃. The test results are shown in Table 3:

Table 3 Module Key Parameters

Channel Number	Transmit Optical Power (dBm)	Receive Sensitivity @5E-5 (over 100m@OM4 Fiber) (dBm)	Power Consumption (W)
CH1	-1.86	-12.61	1.74
CH2	-2.36	-12.97
CH3	-2.12	-13.39
CH4	-1.84	-12.10

The optical eye diagram of the sample module was tested at a module case temperature of 70℃. The test results are shown in Table 4:

The parameters of the optical eye diagram are shown in Table 5:

Table 5 Optical Eye Diagram Parameters

Channel Number	Extinction Ratio (dB)	P-P Jitter (ps)	Rise Time (ps)	Fall Time (ps)	Margin value (%)
CH1	5.71	8.17	15.37	20.12	45.8
CH2	5.93	8.75	15.76	19.97	41.6
CH3	5.71	8.17	15.37	20.12	45.8
CH4	5.93	8.75	15.76	19.97	41.6

Actual test data show that the key parameters of Moduletek’s QSFP-100G-SR4-C-G11 optical module are consistent with the definitions in the official datasheet, and its performance is comparable to that of the same-type modules officially advertised by Cisco.
