Advantages of 100G Single Lambda
Compared with traditional four-channel modules, 100G Single Lambda modules not only have significant cost advantages, but also have greater flexibility and convenience in network upgrades. Next, we will delve into the application advantages of FS's 100G Single Lambda module and its huge potential for network architecture and performance improvement.
Reducing Data Center Costs
Cost reduction through a simpler structure is a cornerstone benefit of 100G Single Lambda optics. Recognized by IEEE and the 100G Lambda MSA, the consortium responsible for establishing optical interface specifications for 100G and 400G, this technology offers significant cost savings. By transitioning from four wavelengths to one, or lambda, the cost can be reduced by over 40%.
Conventional data center networks often rely on intricate, multi-wavelength systems to achieve high data transfer rates. These setups demand a plethora of components, including Clock Data Recovery (CDR), multiplexers, demultiplexers, multiple lasers, and optical modules, leading to heightened capital and operational expenses. In contrast, 100G Single Lambda achieves impressive data speeds with just a single signal, thereby streamlining the network infrastructure.
Transmitter: a DSP, CDR, Laser Driver (LD), and laser
Receiver: a DSP, CDR, Trans-Impedance Amplifier (TIA) + Linear Amplifier (LA), and PIN photodiode
Moreover, substantial cost savings stem from the significantly longer transmission distance afforded by 100G Lambda MSA, extending single lambda optics reach to 2km. Compared to the 100G QSFP28 modules limited to 500m, single lambda requires less infrastructure to cover the same distance.
In sum, the streamlined nature of 100G Single Lambda translates into reduced hardware requirements, fewer points of failure, and simplified maintenance, all contributing to lower initial capital expenditures and operating costs.

Satisfying Future Network Upgrade Needs
Network operators can seamlessly enhance network capacity by stacking multiple 100G single lambda modules, accommodating the evolving demands of future applications without the need for extensive infrastructure overhauls.
For instance, 400G QSFP-DD optical transceivers integrate 4x 100G PAM4 lanes to establish a cost-effective pathway to 400G. Leveraging the PAM4 signaling technique, these transceivers maintain backward compatibility with 100G single lambda cables. By utilizing 100G single lambda transceivers, connectivity between 400G device ports and existing 100G breakouts can be effortlessly established.
In scenarios where a network comprises devices with 100G QSFP28 ports, a phased upgrade to 400G can be executed site-by-site, ensuring seamless integration with the remaining 100G ports without compromising port bandwidth. This approach minimizes downtime, facilitates gradual upgrades, and avoids the financial strain of full-scale replacements.

Anticipated developments, such as PAM8 signaling, are poised to emerge in the coming years to meet the escalating demands for high data rates, low power consumption, and minimal latency across diverse applications.
