Verizon successfully carried Juniper OC-768 traffic on its Richardson, TX, field trial network to 3040 and 2560 km, respectively, using Minteras 40-Gb/s RZ-DPSK and CS-RZ transponders over Xteras all Raman Ultra Long Haul system loaded with 68 times 10 Gb/s channels

Unrepeatered 100G Transmission Over 520.6 km of G.652 Fiber and 556.7 km of G.654 Fiber With Commercial Raman DWDM System and Enhanced ROPA

We report the results of 100G unrepeatered transmission aimed at achieving the longest distance without any inline active elements. The unrepeatered transmission system uses commercial distributed Raman pump modules, enhanced ROPA, and real-time processing coherent 100G transceivers (PM-QPSK) with soft-decision FEC. Two types of ultra-low loss fibers, G.652B and G.654B compliant, are fully characterized and used as span fiber. First, a single 100G channel is successfully transmitted over 520.6 km of G.652B fiber (86.2 dB) in a lab trial. Second, cabled large effective area, ultra-low loss G.654B fiber in a field environment is used as span fiber. A single 100G channel and four 100G channels are transmitted over 556.7 km (90.2 dB) and 523.2 km (84.8 dB), respectively.

150 x 120 Gb/s unrepeatered transmission over 409.6 km of large effective area fiber with commercial Raman DWDM system

15 Tb/s unrepeatered transmission is achieved over 409.6 km (68.2 dB) of large effective area fiber using forward and backward distributed Raman amplification and a remotely-pumped erbium-doped optical amplifier. This result provides a record capacity-reach product of 6.14 Pb/s-km over a single fiber type. We also demonstrate channel growth from 10 to 150 waves within 61 nm amplification bandwidth.

We review recent advances in the technologies required for high-speed unrepeatered transmission systems, with a specific focus on distributed Raman amplification. We also report several experimental demonstrations with record capacity and reach combinations.

This paper reports record unrepeatered transmission results using forward and backward distributed Raman amplifications, large effective area ultra-low loss fiber and enhanced ROPAs with additional pumping fibers. Coherent 100 Gb/s with PM-QPSK modulation format and OOK 10G transmission are demonstrated over 607 km (97.2 dB) and 632 km (101.0 dB), respectively.

150 × 120 Gb/s unrepeatered transmission over 333.6 km and 389.6 km (with ROPA) G.652 fiber

A record capacity of 15 Tb/s unrepeatered transmission has been demonstrated over 333.6 km (55.4 dB) and 389.6 km (64.3 dB) with ROPA. All transmission results have been achieved with G.652 fiber using forward and backward distributed Raman amplification.

Raman Amplification for High-Capacity, Long-Haul Networking

The threat of a capacity crunch in the worldwide fiber communications system, n and the availability of inexpensive, high-power diodes as pump sources for Raman n amplification, has attracted new interest in the virtues of a decades-old n technology.
