NeoPhotonics

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 to demo 64GBd micro-modulator at OFC 2017

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 begins sampling 8x16 multicast switch modules

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.

NeoPhotonics samples PAM4 based 400G CFP8 transceiver

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.

NeoPhotonics introduces low-power 28Gbaud EML with integrated driver

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.

NeoPhotonics samples ClearLight CFP-DCO pluggable coherent module

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.

NeoPhotonics targets 600G with 64G coherent receiver

NeoPhotonics is sampling a Class 40 high-bandwidth micro intradyne coherent receiver (HB-ICR) capable of supporting 64Gbaud symbol rates, double the bandwidth of a standard 32Gbaud coherent receiver.

The HB-ICR supports higher-order modulation up to 64QAM which, when coupled with the company’s ultra-narrow linewidth laser, would enable single wavelength data transmission rates of up to 600Gb/s over distances of up to 80km.

PRODUCT

NeoPhotonics demonstrates 16x16 multicast switch

NeoPhotonics will demonstrate a 16x16 multicast switch (MCS) without drop-side amplifiers on March 26 at OFC 2015 in Los Angeles, California. The 16x16 MCS comprises four modular, low-loss 4x16 MCSs which can be cascaded to encompass 16 directions. The demonstration is intended to show how the low insertion loss of the MCS, when combined with a high-sensitivity coherent receiver, can eliminate the need for drop-side amplifiers in metro networks.

PRODUCT

NeoPhotonics exhibits micro integrated coherent receiver

Components and subsystems developer NeoPhotonics has launched a micro-integrated coherent receiver (Micro-ICR), which is designed to support the Optical Internetworking Forum (OIF) implementation agreement OIF-DPC-MRX-02.0, Type 1. The new receiver is suitable for use in coherent analogue CFP2-ACO pluggable modules as well as in high-density line cards.
