H3C QSFP-100G-BIDI-MM850 is a single-fiber bidirectional (BiDi) optical module based on the 100GBASE-SR SWDM4 standard, designed for short-distance multimode fiber transmission. The module adopts QSFP28 package, supports duplex LC interface, and has an operating wavelength of 850nm, 880nm, 910nm and 940nm. The maximum transmission distance can reach 100 meters (OM4 fiber) or 150 meters (OM5 fiber). Its core advantage is that it can reuse the existing 10G multimode fiber infrastructure to help users achieve a smooth upgrade from 10G to 100G Ethernet at a low cost. The 100G BiDi QSFP28 module complies with the QSFP28 MSA and IEEE 802.3bm CAUI-4 standards, and has a built-in digital diagnostic monitoring (DOM) function, which can monitor key parameters such as optical power and temperature in real time.
How Does QSFP-100G-BIDI-MM850 Work?
The H3C QSFP-100G-BIDI-MM850 realizes single-fiber bidirectional transmission through short wavelength division multiplexing (SWDM4) technology. Specifically, it multiplexes 4 wavelengths (850nm, 880nm, 910nm, 940nm) into one optical fiber, each channel uses 25G NRZ modulation, and four channels are parallel to achieve a total bandwidth of 100G. The transmitter uses VCSEL laser, and the receiver uses PIN photodiode, combined with Macom chip and COB (chip-level packaging) technology, to optimize signal processing efficiency and ensure a bit error rate (BER) ≤5E-5. In addition, the module supports hot-swappable functions, which can be installed or replaced without interrupting the network.
What are the Features of QSFP-100G-BIDI-MM850?
1. High compatibility and cost-effectiveness: The QSFP 100G SR BD can be seamlessly compatible with existing 10G multimode optical fiber systems, avoiding the need to replace wiring due to upgrades, and significantly reducing deployment costs.
2. Low power consumption and high reliability: The power consumption is only ≤3.5W, with an industrial-grade temperature range (0~70°C) and strict spectral test, eye diagram test (mask margin>20%) and temperature test to ensure stable operation in complex environments.
3. Flexible network upgrade solution: Support branching applications (such as splitting into 4×25G links), adapt to mixed-rate network architecture, and meet the high-density connection requirements of data center leaf-spine architecture.
4. Plug and play and easy maintenance: Real-time monitoring of link status through DOM function, combined with interoperability verified by real machine environment testing, simplifies operation and maintenance complexity.
What are the Typical Application Scenarios of QSFP-100G-BIDI-MM850?
1. Data center interconnection: Used for short-distance high-speed connection between servers and leaf-spine switches to improve data throughput efficiency and support high-bandwidth services such as AI training and big data analysis.
2. Enterprise network upgrade: By reusing existing optical fiber resources, it can be quickly upgraded to a 100G network, which is suitable for the interconnection between the core layer and the distribution layer of the enterprise.
3. Education and scientific research network: For example, in H3C network equipment purchased by institutions such as Northeast Normal University, this type of module is used to expand the 10G link of the core switch to meet the needs of high-concurrency teaching and scientific research data transmission.
4. Split line deployment scenario: Split the 100G port into 4x 25G links through a splitter, which is compatible with old equipment and extends the network life cycle.
Summary
H3C QSFP-100G-BIDI-MM850 optical module has become an ideal choice for short-distance high-speed network upgrades due to its technical compatibility, low power design and high reliability. As the demand for bandwidth in data centers and enterprise networks continues to grow, this type of module will further promote the development of network infrastructure towards efficiency and flexibility driven by technologies such as 5G and cloud computing.
