We report order-of-magnitude improvements in performance of field-deployable hollow-core fiber cables evidenced by a 38.4Tb/s (800Gb/s-x-48WDM-channels) 20.5km lab-trial using commercial terminal equipment and the demonstration of 1128km/126km reach in full-fill 400/800Gb/s WDM recirculating-loop experiments.

... represent a major advance in deployable HCF technology and open the door to latency sensitive DCI, 5G and Edge applications. Both NANF Riser and LT cable types have been widely deployed in financial trading applications at 10 Gb/s data rates. The two field-deployable NANF cables are >2 km long and are wound on two 0.5 m diameter cable drums (see Fig. 1a). The 5 nested-element NANF fiber design (inset) provides an excellent trade-off between loss, micro/macrobend insensitivity and level of IMI experienced in the cable. Each cable contains 5xNANF strands. In Fig. 1b, we show the spectral transmission plot of the 5 NANF strands in the LT cable. The best NANF strand (E2) in the cable has ...

The best NANF strand (E2) in the cable has a loss of <0.6 dB/km across the C and L bands. These strands are then spliced together and looped back to create a total cabled NANF fiber transmission link of 20.5 km (see Fig. 1c). The NANF splices were made using a ...

The best NANF strand (E2) in the cable has a loss of <0.6 dB/km across the C and L bands. These strands are then spliced together and looped back to create a total cabled NANF fiber transmission link of 20.5 km (see Fig. 1c). The NANF splices were made using a commercial fusion splicer with a proprietary splicing program that ensures a low splice loss (~0.2 dB) can be obtained by trained field installers. Each cable has a total of 4x NANF splices and 2x NANF-SSMF adapters (insertion loss ~0.5 dB), to provide a practical and flexible way of connecting the ...

... CD and DGD versus those previously reported for PBGF HCF cable [6]. Fig. 3a depicts the link used to demonstrate a field-deployable NANF cable with commercial equipment in a high throughput DCI application. It comprises Ciena line equipment (EDFAs, WDM multiplexer (MUX) and demultiplexer (DEMUX)) as well as 20.5 km of cabled hollow-core NANF (see Fig. 1c). An optical isolator disables the post amplifier return loss shutoff. Two types of transmission equipment, namely WaveLogic 5 Extreme line rate adjustable 200G-800G coherent optics and WaveLogic 5 Nano 400ZR QSFP-DD coherent pluggable, WL5e and WL5n, respectively, are tested separately. In each test a bulk modulated WDM spectrum (47 ...

... channels are amplified with a Ciena EDFA and propagated through 20.5 km of cabled NANF. The cables are configured as described in section 2 and illustrated in Fig. 1. The signal at the receive end is amplified, demultiplexed and sent to the receiver. The bit error rate (BER) at the receiver is averaged for 300 seconds, then converted to an effective signal to noise ratio (ESNR): the SNR is obtained from the BER assuming AWGN. Fig. 4 shows the ESNR margin (difference between the measured ESNR and ...
