A new implementation agreement for low-power consumption will see small modules push technological barriers, finds Andy Extance
The data centre has created demand for an infrastructure that provides greater bandwidth and higher data rates, but how has this impacted the market for optical components?
NeoPhotonics has made available its suite of 64 GBd optical components for coherent systems operating at 600G and 1.2T, now shipping to customers.
Consisting of three critical optical components - a 64 GBd coherent driver modulator, 64 GBd coherent intradyne receiver and an ultra-narrow linewidth tuneable laser – the suite works together to enable customers to implement single channel 600G or dual channel 1.2T data transmission over datacentre interconnect (DCI) distances of 80 km.
Components and subsystems developer NeoPhotonics will demonstrate its pluggable coherent CFP2-ACO module designed for single-wavelength transmission at 400G and beyond at OFC 2017 in Los Angeles, on 21–23 March.
NeoPhotonics (booth 3017) will be showing a selection of products that have recently begun sampling to customers. First up are its 400G CFP8 transceiver modules, designed for data centre interconnect and client-side telecom applications over distances of up to 10km. As part of this development, NeoPhotonics recently announced an electroabsorption modulated laser (EML) with the driver integrated with the EML at the chip-on-carrier level.
NeoPhotonics will demonstrate its new 64Gbaud, polarisation-multiplexed, quadrature micro-modulator (Micro-MOD) at the OFC 2017 Exhibition in Los Angeles, on 21–23 March.
The micro-modulator represents a significant step in enabling small form factor capability for next-generation high-speed optical links. When coupled with a high-bandwidth Micro-ICR and ultra-narrow linewidth tunable laser, the Micro-MOD will enable 400G and 600G coherent transceiver modules and line card applications that require small size, high bandwidth and low power dissipation.
NeoPhotonics has begun sampling a Twin 8x16 multicast switch (MCS) module with an integrated amplifier array for use in high performance colourless-directionless-contentionless (CDC) networks.
The 8x16 MCS can drop channels from any of eight different directions through any of 16 different ports without contention, even if identical wavelengths coming from different directions are dropped at the same time. An optional 17th port is available for network monitoring and control. The MCS modules also have a “twin” circuit to perform the equivalent add functions.
Components and subsystems developer NeoPhotonics has begun sampling of its 400G CFP8 transceiver modules, designed for data centre interconnection and client side telecom applications. This represents the first step on NeoPhotonics’ 400G roadmap for these applications.
NeoPhotonics’ 400G CFP8 transceiver is compliant with the IEEE 802.3bs 400 Gigabit Ethernet specifications 400GBase-LR8 for 10km links and 400GBase-FR8 for 2km links, which are based on 4-level pulse amplitude modulation (PAM4) signals and eight DWDM channels on duplex singlemode fibre.
Components and module developer NeoPhotonics has announced a low power consumption 28GBaud externally modulated laser (EML) with an integrated driver IC, which is designed for data centre and client-side optical transceivers at data rates of 100G, 200G and 400G.
With a power consumption of under 3.5W, the CMOS-drivable EML is the first EML to meet the strict power consumption requirement for QSFP28 modules, the company claims.
Optical components and subsystems developer NeoPhotonics has initiated sampling of its coherent CFP-DCO module as the latest member of its ClearLight family of pluggable coherent modules.
Using the latest advances in 16nm digital signal processor (DSP) chips, the ClearLight digital coherent optics (DCO) platform integrates all the necessary elements to form a complete coherent transceiver that can be plugged into any client port to extend the range and capacity of optical transmission.
