QSFP+ Active Optical Cable
40 Gb/s Integrated Active Optical Cable (AOC)
Offering a lower cost solution than QSFP+ transceivers with MPO cables, the QSFP-CBL-xMM is a 4-channel pluggable integrated Active Optical Cable assembly for short-range data communication and interconnects applications. The assembly contains four channels in each direction with 40 Gb/s aggregate bandwidth at distances of up to 5 meters (16 ft.). The electrical interfaces use 38-contact edge type connectors, compliant with SFF-8436. The AOC is QSFP+ MSA compliant, with low power consumption and a light weight.

FEATURES
- Four independent transmitters, and four independent receivers, all operate at 10 Gb/s
- Bidirectional operation, 4×10 Gb/s per direction
- Allows optical interoperability up to 5m (16 ft.) using an integrated Active Optical Cable assembly
- Multimode at 850 nm
- Hot pluggable
- Interoperable with other IEEE-compliant 40GBASE interfaces
- RoHS-6 compliance
