Objectives

  • Demonstration of a complete ecosystem for high-speed data transmission through multi-core fibers for short-haul link to achieve a capacity of 448 Gbps

  • Laboratory test with spooled fiber - 4 core (10 km) for capacities from 100 Gbps to  6.4 Tbps with Pol Mux + PAM4 + 4 Wavelengths + 4 cores

  • Field test of the above with cabled fiber- 4 core (2.5 km underground and 1 km aerial); 12 strands of 4 core, 12 strands of SMF ; The 12 strands to be looped back with min loss splicing.

Comparison of performance of MCF ; 4-core a with SMF

  • Use-case demonstration for both analog RFoF and Digital high speed communication in the field.

Deliverables

Modulator-based optical frequency comb derived from a single laser with variable spacing, 4 lines with variable frequency separation, uniformity better than 1 dB, OSNR better than 20 dB

  • Access optical link with 10 km multi-core fiber (four core fibers) with CoT fiber and fan-in/fan-out working at a net data rate of 6.4 Tbps with FEC BER using the comb source. Optimal modulation and pulse shaping  to be used. DSP algorithms to be developed

  • Field demonstration with multicore fibers deployed in field- both underground and aerial implementation, testing of OOK, PAM4 and coherent data transmission

  • Field demonstration of multicore aerial fibers for RFoF fronthaul
