OSFP is a new type of 400G optical module packaging type, which has eight high-speed electrical channels and an integrated heat sink, which can greatly improve heat dissipation performance and is therefore highly regarded by all parties. Mshine Technology will focus on introducing the types and connection schemes of 400G OSFP optical modules for you to better understand them.
Introduction to 400G OSFP Optical Module Types
Currently, there are 400G OSFP photosynthesis modules on the market with 400G OSFP SR8, 400G OSFP DR4, 400G OSFP DR4+, 400G OSFP FR4, 400G OSFP 2*FR4 and 400G OSFP LR4.
Among them, “SR” refers to the use of multimode fiber to achieve transmission distances of 70 meters, 100 meters, or 150 meters, and “8” indicates that the module has 8 fiber channels; DR “refers to the use of single-mode fiber to achieve a transmission distance of 500 meters, and” 4 “indicates that the module has 4 fiber channels; XDR4 “is an extended version of” DR4 “; FR “refers to the use of single-mode fiber to achieve a transmission distance of 2 kilometers; LR “refers to a transmission distance of 10 kilometers that can be achieved using single-mode fiber.
Introduction to Connection Scheme for 400G OSFP Optical Module
400G OSFP SR8 optical module
The 400G OSFP SR8 optical module can be used in conjunction with multimode fiber, with a transmission distance of up to 100 meters. Therefore, the 400G OSFP SR8 optical module is more suitable for short-range switch interconnection or multi-channel data transmission.
① Connect two 400G OSFP SR8 optical modules through a 16 core MTP fiber optic jumper.
② Connect the 400G OSFP SR8 optical module to the two 200G SR4 optical modules at the opposite end through a 16 core MTP to 2 * 8-core MPO branch fiber jumper, achieving multi-channel data transmission.
③ Connect the 400G OSFP optical module to the 8 50G SFP optical modules on the opposite end through a 16 core MTP to 8 * LC duplex branch fiber jumper.
400G OSFP DR4 optical module
Due to the use of 100G PAM4 and its maximum transmission distance of 500 meters, the 400G OSFP DR4 optical module is suitable for 400G-100G network connections ranging from 150 to 500 meters. The 400G OSFP DR4 optical module can be connected to four 100G DR4 optical modules at the opposite end through a 12 core MTP to 4 * LC duplex branch fiber jumper.
400G OSFP DR4+ optical module
The 400G OSFP DR4+ optical module is equivalent to an upgraded version of the 400G OSFP DR4 optical module, with a longer transmission distance of up to 2 kilometers, making it more suitable for 400G-100G network connections within 2 kilometers. The 400G OSFP DR4+ optical module can be connected to four 100G DR4 optical modules at the opposite end through a 12 core MTP to 4 * LC duplex branch fiber jumper, achieving a transmission requirement of 2 kilometers.
400G OSFP FR4 optical module
The 400G OSFP FR4 optical module uses four CWDM wavelength uncooled EML lasers, which are more suitable for 400G interconnection. The 400G OSFP FR4 optical module can be connected through LC duplex fiber jumpers.
400G OSFP FR8 optical module
Unlike the 400G OSFP FR4 optical module, the 400G OSFP FR8 optical module is a 2 * 200G optical module that uses 50G PAM4 modulation technology and has eight built-in circuit channels, making it more suitable for multi-channel data communication. Normally, the 400G OSFP FR8 optical module can be connected to the 200G FR4 optical module at the opposite end through a 2 * CS to 2 * LC duplex branch fiber jumper.
The 400G OSFP optical module has been widely used in advanced high-performance computing center network architectures, with ultra large bandwidth and low latency meeting future network requirements. The application of 400G OSFP optical modules will become increasingly widespread in the future. Solving the challenges of chip supply chain and ensuring the stability of device solutions will become a key factor for optical module manufacturers to dominate the market.
