OSFP 800G DR8 PAM4 1310nm 500m
Walsun’s OSFP-800G-DR8D-FLT is fully compatible with NVIDIA’s MMS4X00-NM-FLT. The OSFP transceiver module is designed for use in 800 Gigabit Ethernet links over 500m single-mode fiber. The module has 8 independent electrical input/output channels operating up to 106.25Gbps per channel. This transceiver consists of two transmitter/receiver units, with each operating on a set of wavelengths on the ITU G.694.2 CWDM at 1310nm. The transmitter path of the module incorporates a bi-directional PAM4 re-timer ASIC integrated with an EML laser and an 8-channel internal driver. On the receiver path, used 8 photodiodes and two 4-channel TIA arrays, along with the PAM4 re-timer.
Warranty : 30-Day Free Return, 3-Year Free Replacement, 5-Year Warranty, Lifetime After-sales Technical Support.

Q:Can this module be connected to 400G modules?
A:Yes, this OSFP-800G-2xSR4 optical module can be connected to two 400G SR4 optical modules via two 12-core multimode fiber patch cords.
Q:Can 400G OSFP modules be used for 800G OSFP ports?
A:Yes, 800G OSFP ports are backward compatible with 400G OSFP as long as the physical form factor is compatible.
Q:Can I use 800G OSFP optical modules for 800G QSFP-DD ports?
A:No, OSFP and QSFP-DD are different size packages, the physical size is not the same, so they are not compatible.
Q:Can different packages be interconnected at the same rate, such as OSFP and QSFP-DD?
A:OSFP and QSFP-DD are just physical form factors of the modules, as long as the modules are of the same type (e.g., SR4 or DR4), they can be interconnected.
Q:What is the difference between 8×100 (e.g. SR8) and 2×400 (e.g. 2xSR4) for 800G OSFP optical modules?
A:8×100G refers to the transmission of 8 channels of signals with 100G per channel on both the optical and electrical sides, while 2×400G is the transmission of 2 sets of 4-channel signals with 100G per channel.
