800G OSFP
Overview: 800G OSFP (Octal Small Form Factor Pluggable) Optical Transceivers represent the latest generation of pluggable fiber modules supporting aggregate data rates up to 800 Gbps. Built on the OSFP MSA (Multi‑Source Agreement), these modules utilize eight high‑speed lanes of 100 Gbps each (8 × 100G PAM4). They are designed for next‑generation data center architectures requiring ultra‑high throughput, superior thermal performance, and energy‑efficient operation.

FAQ – 800G OSFP Optical Transceivers
1. What is an 800G OSFP transceiver?
An 800G OSFP transceiver is an advanced optical module supporting eight 100 Gbps lanes of PAM4 signaling, delivering up to 800 Gbps aggregate bandwidth for high‑speed data center networks.
2. What are the main types of 800G OSFP modules?
Main variants include OSFP‑SR8 (100 m MMF), DR8 (500 m SMF), FR4 (2 km SMF), and LR4 (10 km SMF), each optimized for different network reach requirements.
3. What connector interfaces do these modules use?
OSFP SR8 and DR8 use high‑density MTP/MPO‑16 connectors, while FR4 and LR4 use dual CS or LC duplex connectors for single‑mode fiber.
4. Can an 800G OSFP break out into multiple 400G or 100G channels?
Yes. The 8‑lane design supports 2 × 400G breakout (dual FR4) or 8 × 100G split connections using appropriate cables and adapters.
5. How does OSFP differ from QSFP‑DD modules?
OSFP offers better thermal efficiency and larger mechanical housing for higher power (≤ 16 W) compared to QSFP‑DD, and it natively supports 800 Gbps without signal de‑multiplexing.
6. Is OSFP backward compatible with QSFP‑DD ports?
Yes, with a mechanical adapter (OSFP‑to‑QSFP‑DD), some 400G systems can interface with 800G OSFP modules at reduced speed.
7. What is the typical power consumption for 800G OSFP?
Power varies by type — about ≤ 12 W for SR8/DR8 and up to 16 W for FR4/LR4 models due to cooling and signal conditioning requirements.
8. Which standards define 800G OSFP modules?
These modules comply with OSFP MSA, IEEE 802.3ck / 802.3df for 800G Ethernet, and 100G PAM4 electrical standards as defined by OIF‑CEI specifications.
