3.Internal functions and technology

Table 3: Internal Integration Function Units

Functional Unit Description

Integrated tunable laser with high stability and narrow linewidth built-in external cavity tunable laser is the core light source for generating DWDM wavelengths.

The integrated coherent transmitter includes IQ modulator, polarization combiner, etc., to complete the modulation of DP-QPSK optical signals.

The integrated coherent receiver includes a local oscillator laser, a 90°mixer, a balanced detector, etc., to complete coherent reception and optoelectronic conversion.

The integrated DSP chip digital signal processor is the module"brain" responsible for completing all complex algorithms such as digital to analog/analog-to-digital conversion, FEC encoding and decoding, dispersion compensation, polarization demultiplexing, carrier phase recovery, etc.

The integrated microcontroller is responsible for module initialization, status monitoring, alarm reporting, and communication management with the host board.

4.Performance indicators and transmission capability

Table 4: Transmission Damage Tolerance and Distance

Explanation of Damage Type Tolerance Capability

Dispersion tolerance>± 40000 ps/nm, fully digital compensation is achieved through DSP algorithm without the need for external dispersion compensation module.

Polarization mode dispersion tolerance>20 ps meets the PMD requirements of the vast majority of deployed fiber links.

The typical transmission distance is 1500+kilometers on G.652 fiber optic cable, using standard HD-FEC, considering the non electric relay distance under typical optical amplifier design.

Forward error correction supports standard hard decision FEC (HD-FEC), which complies with ITU-T G.709 and provides a net coding gain of approximately 6.5dB, making it the foundation for long-distance transmission.

5.Key features and advantages

Table 5: Analysis of Core Advantages

Characteristic advantages

The pluggable module is separated from the host board and supports hot swapping.Easy to stock, maintain, and upgrade separately, reducing operation and maintenance costs and complexity.

Tunability: One module can replace multiple fixed wavelength modules, greatly simplifying spare parts inventory and wavelength planning, and is an essential feature of ROADM networks.

The fully integrated coherent optical communication system is integrated into a small package, greatly improving the density of board ports and system integration.

The powerful DSP capability of digital signal processing can adaptively compensate for various transmission damages, reduce the stringent requirements for optical link engineering, and enhance system robustness.
