8 Tb/s unrepeatered transmission of real-time processed 200 Gb/s PDM 16-QAM over 363 km

We present a 40 × 200 Gb/s unrepeatered transmission experiment of 4 b/s/Hz spectral efficiency over a record distance of 363 km applying co-Raman pumping at the transmitter and a ROPA with third-order Raman pumping at the receiver.

80 × 200 Gb/s 16-QAM unrepeatered transmission over 321 km with third order Raman amplification

We show 80 × 200 Gb/s transmission over 321 km of low-loss fiber with third order Raman amplification without ROPA. We investigate narrow channel spacing down to 37.5 GHz, targeting a capacity of 21 Tb/s.

Ultra-long 610 km unrepeatered transmission of 100 Gb/s using single fibre configuration

We report a 100 Gb/s unrepeatered transmission over a record distance of 610 km using advanced technology such as PDM-RZ-BPSK modulation with coherent receiver and third-order Raman pumping while using the same single ultra-low loss fibre for both signal and pumps.

15.4 Tb/s C-Band Only Unrepeatered Transmission of Real-Time Processed 200 Gb/s PDM-16 QAM over 355 km

We present a record 77 × 200 Gb/s, C-band only unrepeatered transmission experiment over 355 km, applying a booster at the transmitter side and a ROPA with third-order Raman pumping at the receiver end.

6 Tb/s unrepeatered transmission of 60 × 100 Gb/s PDM-RZ QPSK channels with 40 GHz Spacing over 437 km

We present a 60 × 100 Gb/s unrepeatered transmission experiment at 2.5 b/s/Hz spectral efficiency over a record distance of 437 km of ultra-low loss fibre, with a high power booster and third-order Raman pumping. We also assess the penalty of 40 GHz compared to 50 GHz channel spacing.
