400G QSFP-DD AOC

The TSQS-854HG-XXXC is an Eight-Channel, Pluggable, Parallel, Fiber-Optic QSFP Double Density for 2x200 Gigabit Ethernet Applications. This AOC is a high performance module for short-range multi-lane data communication and interconnect applications. It integrates eight data lanes in each direction with 8x26.5625GBd. Each lane can operate at 53.125Gbps up to 70 m using OM3 fiber or 100 m using OM4 fiber with FEC. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 76 contact edge type connector.

  • Hot-pluggable QSFP-DD form factor

  • 8 channels full-duplex transceiver modules

  • Transmission data rate up to 53Gbps per channel

  • 8x53Gbps PAM4 transmitter and PAM4 receiver

  • 8 channels 850nm VCSEL array

  • 8 channels PIN photo detector array

  • Internal CDR circuits on both receiver and transmitter channels

  • Power consumption < 10W per end

  • Built-in digital diagnostic functions

  • Operating case temperature 0°C to 70°C

  • RoHS compliant



Applications of 400G QSFP-DD AOC

  • 400G 100m Ethernet Applications
