Test Report For Moduletek SFP-OC48-LR2-DWDM-52.52-C-D12 Optical Module

Time: 2024-12-11
        Moduletek offers the SFP-OC48-LR2-DWDM-52.52-C-D12 optical module, which supports GE Ethernet transmission over single-mode fiber (SMF) up to 120km. Moduletek Laboratory conducted tests on the product prototype to help users fully understand its performance indicators and actual in-device operation.
1. Product Description
        The Moduletek SFP-OC48-LR2-DWDM-52.52-C-D12 optical module supports a 120km link length over G.652 standard SMF and operates within the commercial temperature range (0~70℃). Its official ordering information and physical appearance are shown below:

2. Module On-Board Identification Test
        Connect the SFP-OC48-LR2-DWDM-52.52-C-D12 module to a Cisco N9K-C93180YC-EX switch and connect the fiber patch cord. The switch can normally recognize the module, including key information such as vendor name, transmission rate, wavelength, and transmission distance. DOM data can be read normally, and all data are within the threshold range without alarms.

3. Key Parameter Testing
    a. Multi-Temperature Performance Test
        The performance indicators of the SFP-OC48-LR2-DWDM-52.52-C-D12 sample module were tested on a test board under laboratory conditions with module case temperatures of 0℃, 35℃, and 70℃. The sensitivity test required no error codes for 5 minutes, and optical power and power consumption were recorded when the module was in stable operation. Test results are shown below:
