The 800GBASE 2 x SR4/SR8 OSFP Optical Transceiver is an InfiniBand and Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, SR8 (2xSR4) multimode, parallel, 8-channel transceiver using two, 4-channel MPO-12/APC optical connectors at 400Gb/s each. The parallel multimode, short reach 8-channel (2xSR4) uses 100G-PAM4 modulation and has a maximum fiber reach of 50-meters using 8 multimode fibers. The 50-meter length assumes two optical patch panels in the link.

What are the main categories of 800G optical transceivers?
The main categories of 800G optical transceivers are typically classified based on transmission rate, transmission medium (single-mode or multi-mode), and packaging form. Common classifications include:
Transmission Rate Classification:
- 800G 2*SR4: An 800G optical transceiver based on multi-mode fiber (850nm wavelength), typically used for short-range high-speed transmission within data centers. It uses 8 channels for data transmission and is suitable for shorter distances (e.g., up to 50 meters).
- 800G 2*DR4: An 800G optical transceiver based on single-mode fiber (1310nm wavelength), designed for longer-distance transmission, typically supporting up to 500 meters.
- 800G 2*FR4: Uses single-mode fiber and operates at a 1310nm wavelength, supporting a transmission distance of up to 2 km.
- 800G 2*LR4: Uses single-mode fiber with a 1310nm wavelength, supporting the longest transmission distance of up to 10 km.
Packaging Form Classification:
- QSFP-DD (Quad Small Form-factor Pluggable Double Density): A commonly used packaging form for 800G optical transceivers, offering higher density and the ability to support more fiber channels. It is ideal for large-scale data centers and cloud computing environments.
- OSFP (Octal Small Form-factor Pluggable): Another packaging form for 800G optical transceivers, supporting 8 channels for high-speed data transmission. It is typically used in high-bandwidth, high-density network deployments.
- Transmission Medium Classification:
- Single-Mode Optical Transceivers (SMF): 800G optical transceivers designed for single-mode fiber, suitable for long-distance transmission (e.g., 800G 2*LR4, which can support up to 10 km or more).
- Multi-Mode Optical Transceivers (MMF): 800G optical transceivers designed for multi-mode fiber, used for short-distance transmission (e.g., 800G 2*SR4, typically with a range of up to 100 meters).
What are the common packaging types for 800G optical transceivers?
Common packaging types for 800G optical transceivers include:
- OSFP (Octal Small Form-factor Pluggable):
OSFP is a packaging type specifically designed for ultra-high-speed transmission, supporting 8 optical channels. It offers high density and bandwidth, making it ideal for large-scale data centers and cloud environments. OSFP supports higher power and bandwidth, suitable for more complex network architectures and widely used in high-performance computing and operator networks. - QSFP-DD (Quad Small Form-factor Pluggable Double Density):
QSFP-DD is one of the most common packaging types for 800G optical transceivers. It supports up to 8 channels, with each channel transmitting 100Gbps, enabling 800Gbps total transmission rate. QSFP-DD provides high density and bandwidth and is compatible with earlier QSFP+ and QSFP28 standards, making it widely used in data centers, cloud computing, and high-performance networks.
- QSFP112:
QSFP112 is the latest generation packaging type designed specifically for 800G, supporting 8 channels with each transmitting 112Gbps. It offers higher density and bandwidth capabilities compared to QSFP-DD and is expected to be a standard packaging type for next-generation network devices. QSFP112 is primarily used in high-performance data centers, large-scale cloud computing platforms, and high-speed network environments, offering higher transmission capacity and lower power consumption.
What are the characteristics of 800G optical transceivers in QSFP-DD packaging?
800G optical transceivers in QSFP-DD packaging are characterized by high density and bandwidth. They support 8 channels, with each channel transmitting 100Gbps, resulting in an 800Gbps total bandwidth. These transceivers are backward compatible with QSFP+ and QSFP28, making them suitable for gradually upgrading existing equipment. QSFP-DD modules are compact and ideal for large-scale data centers and cloud computing environments, providing efficient transmission performance. QSFP-DD is primarily used in Ethernet applications, while OSFP is more commonly used in InfiniBand (IB) networks.
What are the characteristics of 800G optical transceivers in OSFP packaging?
800G optical transceivers in OSFP packaging support 8 channels, with each channel transmitting 112Gbps, resulting in an 800Gbps total bandwidth. OSFP offers higher power support and bandwidth, making it suitable for large-scale data centers and high-performance computing applications.
