Coherent announced L-band capable 800ZR/ZR+ tranceivers, a critical component of hyperscaler plans to leverage existing fiber infrasturucre to meet capacitry needs. The devices will be demonstrated at ECOC 2024 in a Juniper PTX Router. The transceiver leverages the Coherent L-band 140 Gbaud IC-TROSA which features an internally designed and manufactured indium phosphide modulator and receiver combined with an embedded wavelength-tunable laser.
With the ever-growing bandwidth demands of DCI and telecom networks, L-band transmission has become essential. L-band ROADM shipments have nearly doubled over the past 12 months, and hyperscale DCI requirements are poised to grow the market for L-band pluggable coherent transceivers even more rapidly.
