Key Technical Details

• Form Factor: QSFP28

• Data Rate: $100$ Gbps (4×25 Gbps)

• Standard: 100GBASE-CWDM4

• Media & Wavelength: Single-Mode Fiber (SMF) at $1310$ nm band

• Technology: CWDM4 (LAN WDM)

• Connector: Duplex LC

• Max Reach: $2$ kilometers (2KM)

• Application: Designed for cost-effective DCI and links within large campus data centers where $10$ km reach is unnecessary. The $2$ km distance is a key differentiator for this standard, offering lower power than the $10$ km LR4 module.

• Model: 100GBASE-LR4 QSFP28 Receive-Only

• Speed & Reach: $100$ Gbps over Single-Mode Fiber (SMF) up to 10 kilometers ($10$ km).

• Function: It is installed in a network device port that only needs to listen for incoming $100$ Gbps traffic and does not need to send any return data.

• Primary Purpose: Optical Monitoring, Troubleshooting, and Traffic Capture. It is used for passive, non-intrusive monitoring of a live fiber link, often in conjunction with fiber tapping or splitting devices.
