Today, 100G QSFP28 transceivers are widely deployed within a range of 100 meters to 40km. However, a challenge arises with traditional 100G QSFP28 modules, as their design is limited to distances not exceeding 40km. Beyond this range, issues like dispersion and optical attenuation increase, leading to decreased signal-to-noise ratio (SNR) and higher error rates.

How to Extend Your 100G Reach to 80km with 100G ZR4 Module?

As data-intensive applications continue to grow, the substantial increase in bandwidth demand requires service providers and network operators to transform their offerings to keep pace. For customers looking to upgrade their 80km 10G links to 100G, they can consider solutions like CFP2-DCO modules or QSFP-DD ZR modules. However, these transceivers offer high-speed transmission and extended distance with increased power consumption. Utilizing the current 10G network with lower capacity or adding extra fibers would be costly and not easily scalable. Thus a 100G solution is needed which could extend their reach beyond 40km——QSFP-ZR4-100G module which can simply and cost-effectively achieve transmission distances of up to 80km.

Key Technologies of 100G ZR4 Module

The development of QSFP 100G ZR4 was driven by customer demand for a practical 100G module with an 80km reach. The key technologies adopted by the 100G ZR4 module are described below:

  • Prevailing configuration for QSFP28: Utilization of four 25G optical and electrical lanes

  • Minimize chromatic dispersion: Operating in the O-band (at 1295, 1300, 1304, and 1309 nm)

  • Compensate for attenuation: Integration of an SOA (Semiconductor Optical Amplifier)

  • Optimize the signal-to-noise ratio (SNR): Implementation of a high-power transmitter

  • Simplify transmission, maintain compatibility: Employing standard Non-Return-to-Zero (NRZ) modulation
