How to use
Install the BlueOptics QSFP-100G-ER4-BO into a compatible QSFP28 port on supported network hardware, ensuring the host device supports 100GBASE-ER4 modules and DDM/DOM if monitoring is required. Connect single-mode LC duplex fiber patch cords to the module, observing correct fiber polarity and secure connectors. After insertion, verify the link status on the host device and confirm diagnostic readings through the management interface if available. For best results, use single-mode fiber and appropriate patch panels or direct patching between transceivers.
Usage recommendations
To achieve reliable 40 km links, use approved single-mode fiber, maintain clean LC connector endfaces, and confirm host compatibility with 100GBASE-ER4 QSFP28 modules and digital diagnostics. Store and handle the transceiver to avoid mechanical shock and contamination of optical surfaces.
