Functional Block Diagram

800G OSFP DR8

General Description

The 800G OSFP DR8 are high-performance, cost-effective transceivers designed for utilization in 800 Gigabit Ethernet links over 500 meters. On transmitter side, the module converts eight channels of 53.125 GBaud (PAM4) electrical data to eight channels of parallel optical signals with data rate of 53.125 GBaud (PAM4). At receiver side, the module converts eight channels of parallel optical signals with data rate of 53.125 GBaud (PAM4) into eight channels of 53.125 GBaud(PAM4) electrical output data.

The product is designed according to the OSFP MSA. It is designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.

Note:

a. Average launch power, each lane (min) is informative and not the principal indicator of signal strength. A transmitter with launch power below this value cannot be compliant; however, a value above this does not ensure compliance.

b. Even if the TDECQ < 1.4 dB, the OMAouter (min) must exceed these values.

c. Transmitter reflectance is defined looking into the transmitter.

Notes:

a. The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level. The receiver does not have to operate correctly at this input power.

b. Average receive power, each lane (min) is informative and not the principal indicator of signal strength. A received power below this value cannot be compliant; however, a value above this does not ensure compliance.

c. Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with SECQ of 0.9 dB.

d. Measured with conformance test signal at TP3 for the BER = 2.4E-4.

e. These test conditions are for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
