It adopts single-fiber bidirectional transmission (WDM) technology, requiring only one fiber to complete bidirectional data transmission, saving 50% of fiber resources; it features a high-density design, using a small-size QSFP28 package, compatible with high-density switch ports; it has strong compatibility, supporting interconnection with mainstream brand switches, allowing for smooth upgrades to existing networks; it supports transmission distances from 100m to 80km, suitable for solutions in data centers and telecom operators.
The key technology used in the 100G QSFP28 BIDI optical module is wavelength division multiplexing (WDM). Traditional optical modules require two fibers to handle "transmit" and "receive" respectively, while BIDI modules, through WDM technology, allow a single fiber to simultaneously carry two different wavelengths of optical signals, such as an uplink wavelength of 1270nm and a downlink wavelength of 1330nm. The two wavelengths do not interfere with each other, like dividing a highway into "two lanes," achieving efficient coexistence.
PAM4 modulation addresses the bandwidth bottleneck faced by traditional NRZ modulation (two-level 0/1) at high speeds. PAM4 (four-level pulse amplitude modulation) improves efficiency through "four-lane parallel" modulation; each symbol carries 2 bits of information, doubling the speed compared to NRZ; it is compatible with 50Gbps single wavelengths, easily achieving a total bandwidth of 100G.

In Ethernet, 100G BIDI transceivers are used for 100G BASE connections. They provide 100G speeds via single-core simplex LC fiber, whereas traditional solutions require two cores. This is highly attractive for links in campus network cores and metropolitan area Ethernet aggregation, maximizing the use of existing fiber optic infrastructure and avoiding costly fiber expansion projects for speed upgrades.
In the interconnection of switch and router devices, 100G BIDI modules act as critical interfaces in device clusters, stacks, or core interconnection scenarios. They enable a single device to deploy interconnect links without increasing the number of fiber cores, improving the deployment flexibility and scalability of network devices.
The 100G BIDI optical module can make full use of existing fiber optic resources, freely upgrade old networks, and save 50% of fiber optic resources under the same bandwidth.
