Optical Components

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.

Optical components developer VI Systems has launched an ultra-high speed fibre-coupled photodetector module designed for test set-ups when developing advanced short-reach optical interconnects.

The D50-1300M module will support data rates of up to 50Gb in non-return-to-zero (NRZ) modulation or pulsed amplitude modulation (PAM) formats. The photodetector operates over an input wavelength range from 840nm to 1550nm, making it compatible with a variety of different protocols and technologies.

Arrayed Fiberoptics has developed what it claims is the world's first non-contact multi-fibre push-on (NC-MPO) optical fibre connector. The patent-pending design could replace the traditional MPO connector in data centre cabling systems, joining ribbon fibres containing 4–24 fibres.

Semiconductor IC developer GigPeak, formerly GigOptix, is now sampling the GX32222, a 32Gb/s dual-channel linear trans-impedance amplifier (TIA) for use in high-speed optical receiver modules operating at 100Gb/s, 200Gb/s and beyond.

Ovum projects that 100G port shipments will continue growing with accelerated compound annual growth rate of 25–30 per cent over the next four years till 2020, while being augmented with next generations of higher-speed coherent single wavelength ports, for both line cards and pluggable modules.

Semiconductor company Broadcom has unveiled a new generation of gearbox PHY IC devices, the BCM82332, BCM82793 and BCM82864, designed for modern data centre and enterprise networking applications.

With the general availability of switch chips that have flexible, multi-speed port interfaces supporting 10G, 40G, 100G and emerging Ethernet speeds, new gearbox PHY solutions are needed to ensure robust signal integrity and optimise port adaption.

MaxLinear, a provider of radio frequency and mixed-signal integrated circuits for communications applications, has unveiled the MxL9207, a quad-channel lithium niobate (LiNbO₃) Mach-Zehnder (MZ) modulator driver IC for next-generation 100Gb/s optical networks.

The MxL9207 supports complex modulation schemes for coherent transmission in ultra-long-haul networks, which have the most challenging system requirements. With a 19mm x 13mm SMT package, the device is suitable for both new and legacy 100Gb/s coherent system designs.

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.

Kaiam, a developer of high-performance datacom optical transceivers, has launched LightScale2, an upgraded optical integration platform enabling ‘unprecedented’ performance and scalability. The company is currently sampling CWDM4 100G QSFP28s modules based on this architecture.

HUBER+SUHNER Cube Optics will present its latest, ultra-compact, extended LAN-WDM optical sub-components at this year’s European Conference on Optical Communication (ECOC) in Düsseldorf, Germany, booth 259.

The new optical sub-components – which conform to the IEEE 802.3bs 400GBase-LR8/FR8 proposal and are compatible with the CFP8 form factor – comprise a compact, directly-reflecting, wavelength multiplexer. The product builds on the proven, reliable design applied in 100GBase-LR4/ER4 and 40GBase-LR4/ER4 transceivers. 

II‐VI, a provider of pump laser modules and micro-optics for optical amplifiers, has introduced new uncooled 980nm pump laser modules that feature patent-pending in-package wavelength stabilisation to enable optical amplification within small transceiver packages. These are increasingly required as high-bit-rate coherent transceivers continue to be designed into ever smaller packages to meet the needs of telecom carriers and cloud service providers for equipment with greater density requirements.
