Suitable for
High-density switch-to-switch links in data centers
Server uplinks requiring 40 Gbit/s fiber connections
Aggregation and spine-leaf network architectures
Upgrading or expanding optical ports in network equipment that accept QSFP modules
Key specifications
Interface type: QSFP form factor for hot-pluggable optical transceivers
Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s) aggregate throughput
Physical form factor: QSFP-compatible pluggable module
Application: fiber optic data transmission for networking equipment
How to use
Install the BlueOptics JG661A by inserting the QSFP module into the compatible transceiver slot of a switch, router or server while the host device is powered according to the vendor’s hot-plug guidelines. After seating the module, connect appropriate fiber optic patch cables to the module’s ports, ensuring correct fiber type and connector alignment. Verify link status and configure the host port as required for speed, duplex and any relevant optical settings in the device management interface.
