Description
QSFP+ Active Optical Cable
F-tone QSFP Active Optical Cable (AOC) FTCQ-8540G-PCT-XX and FTCQ-8540G-PCT-XX*-1 is a high performance integrated cable for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with 40 Gbps aggregate bandwidth. Each lane can operate at 10 Gbps with lengths ranging from one to 100 m. These Active Optical Cables utilize multimode fiber using a nominal wavelength of 850nm. The electrical interface uses a 38-contact edge type connector. F-tone is producing QSFP+ to QSFP+ AOC and QSFP+ to FOUR SFP+ AOC.
Application:
- InfiniBand QDR (4 x 10G), DDR (4 x 5G) and SDR (4 x 2.5G) interconnects
- High Performance and High Productivity computer interconnects
- Data Aggregation, Backplane and Proprietary Density Applications
- PCI-Express, SAS/SATA, Fibre Channel compatible interconnect
- Datacom and Telecom switch and router backplane connections

QSFP AOC Wiki
Active Optical Cable (AOCs) extremely low power consumption, improves overall data center power consumption and thermal efficiency. AOC’s use single mode silicon photonics (SiPh) to enable long transmitting on single mode ribbon fiber. AOC pigtails (QSFP+ to MPO) allow for easy plug in to installed SM structured cabling, thus eliminating the need to pull the AOC through long distances.
AOCs reduced cable bulk compared to larger diameter copper cabling enable deployment of additional ports for increased number of AOCs per system, resulting in more connectivity options and total system cost savings. Optical pluggable QSFP+ MTP† cable assemblies are available in 12-fiber 3.00mm round cable and a robust 4.50mm round cable.
Advantages of Active Optical Cables (AOC) Compare to Copper Twinax Cables
- Longer reach
- Bit Error Rate (BER) 1000 times better than copper cables
- Lower weight and tighter bend radius enable simpler cable management
- Thinner cable allows better airflow for cooling
- Lower power consumption
- No need for power-hungry conditioning ICs on the host board
Advantages of Active Optical Cables (AOC) Compare to Optical Transceivers
- Datacenter/Consumer friendly:
- No cleanliness issues in optical connector
- Cost-optimized:
- Not constrained by optical interface specifications driven by longer reach applications
Disadvantage: Cannot be routed through optical patch panels
