100+ Gbps/λ 50 km C-Band Downstream PON Using CD Digital Pre-Compensation and Direct-Detection ONU Receiver

Journal of Lightwave Technology, 2020
We experimentally demonstrate a single-wavelength 100 Gbps downstream PON transmission aided by chromatic dispersion digital pre-compensation (CD-DPC) using simple digital signal processing (DSP) finite impulse response (FIR) filters in combination with ...

112-Gb/s/λ Downstream Transmission for TDM-PON with 31-dB Power Budget using 25-Gb/s Optics and Simple DSP in ONU

Optical Fiber Communications Conference and Exhibition, 2020
We experimentally demonstrate 112-Gb/s/λ PAM-4 transmission based on 25-Gb/s optics. Over 31-dB power budget is achieved by using OLT-side pre-equalization, amplification and only simple FFE in ONU.

224 Gbit/s Coherent PON Downstream Using a Wavelength-Uncalibrated LO and Blind Locking During ONU Startup

Optical Fiber Communications Conference and Exhibition
We experimentally demonstrate a novel blind LO-locking technique for $224 \text{Gbit} / \text{s}$ coherent PON downstream that is applied during ONU startup and allows using wavelength uncalibrated LO lasers in the ONU module. © 2024 The Author(s)

Bidirectional TFDM 200 G coherent PON with a simplified receiver at the ONU side.

Optics Letters
Time and frequency division multiplexing (TFDM) coherent passive optical networks (PONs) are considered as a promising candidate for future optical access networks due to the advantage of high sensitivity, high spectral efficiency, and flexibility.

Design of 2D-WH/TS OCDMA PON ONU Receiver with FLC Technique

IEEE International Conference on Recent Trends in Electronics, Information & Communication Technology, 2019
This paper exercises fuzzy logic for the prediction of channel response to a two dimensional-wavelength hopping /time spreading optical code division multiple access (2D-WH/TS OCDMA) code in a passive optical network (PON). A fuzzy logic control (FLC) is

DSM-Based Ultra-Low-Latency ONU Activation for Uninterrupted TDM-PON Services

Journal of Lightwave Technology
Next-generation mobile networks are expected to incorporate ultra-reliable low latency communication (URLLC). However, the activation and ranging process of Time division multiplexing passive optical network (TDM-PON) may provoke conflict to it.

ENB onus and responsibility

Nursing Standard, 1989
I recently applied for the English National Board course 'Care of the Elderly'. I had to attend a formal interview (which was a surprise) at which the senior tutor kept repeating the fact that it was my responsibility to attend post- registration courses as re the UKCC Code of 'Professional Conduct.
