Description
The FiberMania 400G OSFP112 SR4 optical transceiver is a high-performance module designed for short-reach data communication and interconnect applications. By leveraging four independent lanes of 106.25 Gbps PAM4 modulated signals, this transceiver achieves an aggregate bandwidth of 400 Gbps. It utilizes an integrated 850nm VCSEL array and a high-sensitivity PD array to ensure reliable data transmission over multimode fiber, supporting distances up to 100 meters.
This module is fully compliant with the OSFP Management Interface Specification (CMIS) 4.0 and the OSFP MSA 5.0. It features a hot-pluggable design for seamless field upgrades and maintenance, operating on a single +3.3V power supply. With its advanced 400GAUI-4 electrical interface, it provides a streamlined path for data centers transitioning to next-generation high-density networking environments while maintaining power efficiency with a maximum consumption of 9W.

Q&A
Q: Does this OSFP112 SR4 module support backward compatibility with older 400G OSFP slots? A: Yes, as long as the host switch supports the OSFP112 mechanical form factor and the 400GAUI-4 electrical interface. It follows the standard CMIS 4.0 protocol to ensure smooth communication with the host system.
Q: How does the PAM4 modulation benefit the 400G transmission compared to NRZ? A: PAM4 allows for doubling the data rate within the same bandwidth by using four signal levels instead of two. This enables the 106.25 Gbps per lane speed required for 400G performance while maintaining signal integrity over short distances.
Q: Can FiberMania provide custom labeling and firmware coding for specific switch compatibility? A: Absolutely. As a specialist in OEM and private label services, we can customize the EEPROM coding, labeling, and packaging to match your brand identity and ensure 100% compatibility with various network equipment vendors.
Q: What is the primary advantage of the 400GAUI-4 interface over previous generations? A: The 400GAUI-4 interface reduces the lane count from 8 to 4, which simplifies the internal architecture of the module and the host board. This leads to lower power consumption, reduced complexity, and higher port density in modern data centers.
