MCQ-4NSCCC-2K is a QSFP 100G CWDM4 transceiver module designed for100Gb/s optical communication applications. In the transmitter side, the module converts 4 input channels of25Gb/s electrical data to 4 channels of optical signals and then multiplexes them into a single channel. In the receiver side, the module demultiplexes a 100Gb/s optical input into 4 channels optical signals and then converts them to 4 output channels of electrical data. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the IEEE802.3bm,QSFP28 MSA and CWDM4 MSA.Host FEC is required to support up to 2km fiber transmission. The device is Class I laser safety compliant and meets the EU Directive 2002/95/EC for RoHS compliance.
Q: Does the QSFP-100G-CWDM4 module support hot-plugging?
A: Yes, it features a hot-pluggable electrical interface compliant with QSFP28 MSA standards. However, adhere to these conditions:
- Device Status: Perform during low-traffic periods or system standby to prevent electrical surge damage.
- Port Management: Disable the port via CLI (e.g., shutdown command) before insertion/removal.
1. DDM Monitoring
Use Digital Diagnostic Monitoring (DDM) to verify real-time parameters:
- Ensure values stay within the module's specified range.
2. Alarm Indicators
- Abnormal status triggers warning lights for immediate visual identification.
