Scott Swail, VP, Transmission Products, gives an update on Lumentum portfolio of 100G/200G CFP2-ACO and CFP2-DCO coherent pluggable transceiver modules.
CFP2-ACO 100G/200G Pluggable Transceiver
The Lumentum CFP2-ACO 100G/200G pluggable transceiver is a hot-pluggable CFP2 MSA-compatible module designed for 4x32Gbaud (128 Gbps) coherent point-to-point and metro applications.
The transmitter incorporates Lumentum co-packaged indium-phosphide (InP) DSDBR narrow-linewidth laser with indium phosphide dual-cartesian Mach-Zehnder, with polarization multiplexer. The receiver is comprised of a bulk optics de-multiplexer, dual Lumentum InP 90° optical hybrid mixers with integrated balanced PINs followed by dual TIAs.
The module adopts a common C-band flex-grid laser source providing both transmitter and local oscillator signals, calibrated to provide 100 MHz frequency accuracy, and ±6 GHz local off-grid tuning.
The module also includes linear drivers, configured to provide appropriate modulation drive to the MZ modulator, and associated control to maintain over life stability.
An IEEE802.3 Clause 45 compliant 1.2 V LVCMOS MDIO interface is used for control, alarms, monitors, and diagnostics.
The module mechanical outline is the standard CFP2 MSA size (106 mm x 41.5 mm x 12.4 mm). Electrical interfaces are provided through the 104-pin CFP2 MSA-compliant connector, with 4x32 Gbps analog electrical interface and optical interfaces through two LC optical receptacle connectors.
