## Summary description

This CBO BlueOptics QSFP to 4xSFP+ breakout cable (model 49Y7887-BL) is a 3 m, male-to-male passive copper assembly supporting 40 Gbit/s aggregated bandwidth. Designed for connecting QSFP ports to four SFP+ ports in switches, routers or servers, it simplifies port aggregation and migration to 40G infrastructure while maintaining compact rack cabling and low latency.

## Long description

This CBO QSFP to 4xSFP+ breakout cable by BlueOptics is a 3 m passive copper assembly designed to deliver an aggregated 40 Gbit/s connection between a QSFP port and four SFP+ ports. The cable provides a compact, low-latency physical connection for data center and enterprise network equipment, enabling direct port aggregation or migration to 40G infrastructure without additional transceivers.
Advantages
The passive copper construction offers predictable electrical performance and minimal latency for short-reach connections. With a 3 m length and male-to-male QSFP-to-4xSFP+ pinout, the cable reduces the need for multiple separate cables and conserves rack space. Its direct-attach design removes the complexity and cost of separate optical transceivers and simplifies deployment when connecting compatible switches, routers or servers.
Suitable for
 Connecting a QSFP port to four SFP+ ports for link aggregation
 Short-reach 40 Gbit/s server-to-switch or switch-to-switch connections within racks or between adjacent racks
 Migrating existing SFP+ deployments toward consolidated 40G uplinks
 Low-latency applications where passive copper direct attach is acceptable
Key specifications
 Aggregate data rate: 40 Gbit/s (split into four 10 Gbit/s lanes)
 Connector type: QSFP (one end) to 4× SFP+ (other end), male-to-male
 Cable medium: passive copper direct-attach assembly
 Length: 3 m
 Typical use: short-reach interconnect within racks or between adjacent racks
How to use
Insert the QSFP end into the host device QSFP port and plug the four SFP+ connectors into the target SFP+ ports on the receiving device. Ensure both devices support passive QSFP-to-4xSFP+ breakout connections and check port numbering and lane mapping in the device documentation to match link aggregation or port mapping settings. No separate power or transceiver modules are required; handle the cable by the connector housings and avoid sharp bends during installation.
Usage recommendations
Use this passive breakout cable for reliable short-distance connections in racks and adjacent racks. Verify compatibility with your equipment vendor's QSFP breakout support and configure link aggregation or port mapping on both ends. Avoid extended outdoor exposure and maintain bend radius limits to preserve signal integrity.
