400G QSFP-DD SR8 100m

Teosco TEO-QD400G-SR8 8*50Gbps transceiver module is designed for use in 400 Gigabit Ethernet links over 70m on OM3 or 100m on OM4 multi-mode fiber. The module has 8 independent electrical input/output channels operating at 53.125Gbps (PAM4) per channel. This transceiver consists of two transmitter/receiver units, with each operating on 850nm wavelength. The transmitter path of the module incorporates a PAM4 re-timer ASIC with two 4-channel modulator drivers and 8 modulated lasers. On the receiver path, it consists of 8 photodiodes and two 4-channel TIAs, along with the PAM4 re-timer. The electrical interface of the module is compliant with the 400GAUI-8 interface as defined by IEEE 802.3bs. The form factor, optical/electrical connections and digital diagnostics interface are compliant with the QSFP-DD MSA. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP-DD MSA. This type of optical modules is commonly used in data centers, cloud computing, high-performance computing and large-scale networks to achieve high-speed data transmission and communication.
