This product is a 200Gb/s transceiver module designed for 10km optical communication applications. The design is compliant to IEEE802.3bs 200GBASE-LR4 standard. For 200GAUI-8 Electrical interface, the module converts 8 input channels(ch) of 25Gb/s electrical data to 4 channels of LWDM optical signals, and multiplexes them into a single channel for 200Gb/s (PAM4) optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 200Gb/s(PAM4) input into 4 LWDM channels of signals, and converts them to 8 channels output electrical data. For 200GAUI-4 Electrical interface, the module converts 4 input channels(ch) of 50Gb/s electrical data to 4 channels of LWDM optical signals, and multiplexes them into a single channel for 200Gb/s (PAM4) optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 200Gb/s(PAM4) input into 4 LWDM channels of signals, and converts them to 4 channels output electrical data. The central wavelengths of the 4 LWDM channels. It contains a duplex LC connector for the optical interface and a 76-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module. Host FEC is required to support up to 10km fiber transmission. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP-DD Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.

Notes:

1. GND is the symbol for signal and supply (power) common for QSFP-DD modules. All are common within the QSFP-DD module and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the host board signal common ground plane.

2. VccRx, Vcc1 and VccTx are the receiving and transmission power suppliers and shall be applied concurrently. Recommended host board power supply filtering is shown in Figure 3 below. Vcc Rx, Vcc1 and Vcc Tx may be internally connected within the QSFP-DD transceiver module in any combination. The connector pins are each rated for a maximum current of 1000mA.

*Notes:* 1. 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. 2. Even if the TDECQ < 1.4 dB for an extinction ratio of ≥ 4.5 dB or TDECQ < 1.3 dB for an extinction ratio of < 4.5 dB, the OMAouter (min) must exceed the minimum value specified here. The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level. 3. 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. 4. Measured with conformance test signal for BER = 2.4x10-4. 5. These test conditions are for measuring stressed receiver sensitivity. They are not acteristics of the receiver.
