Macom presents complete chipset for 10G PON deployments

Macom Technology Solutions has announced what it believes is the industry’s first and only complete chipset for 10Gb/s passive optical network (PON) applications.

The availability of all products from the same supplier will accelerate the deployment of 10G PON systems by make it easier and more cost-effective for customers to integrate the various parts when designing and building optical line terminal (OLT) and optical network unit (ONU) equipment.

ProLabs launches range of Green 100G transceivers

Compatible transceiver supplier ProLabs has unveiled the first product in a new line of ‘Green’ optical transceivers, which consume 30 per cent less power than traditional devices while offering the same great performance.

The new transceivers employ silicon optical bench (SiOB) technology to align the output from the vertical-cavity surface-emitting lasers (VCSELs) with the physical fibres. This shortens the optical path inside the module by 60 per cent and reduces optical losses, which in turn reduces the power required to operate the device.

MACOM unveils end-to-end 100G single-lambda portfolio

MACOM's 100G Single Lambda Solution leverages the company's 53 Gbaud PAM-4 technology to deliver 100G throughput over a single wavelength.

Macom Technology Solutions has unveiled what it claims is the industry’s first complete 100G single lambda solution for cloud data centre optical interconnects that promises unprecedented system density at even lower cost per bit.

The availability of a complete set of products from a single supplier will enable customers to quickly and easily integrate those components, and get to market faster with the next-generation of 100G interconnects.

Molex updates zSFP+ interconnect system to support 56G channels

Molex says its zSFP+ Interconnect System now supports channels with individual lane data rates up to 56Gb/s PAM-4, providing enhanced signal integrity for next-generation Ethernet and Fibre Channel applications.

The cages and cable assemblies that make up the zSFP+ Interconnect System come in a stacked 2xN configuration to meet the needs of OEMs requiring high-density interconnects. The product range includes EMI-protected ganged cages, which are available in multiple port sizes from 2x1 through 2x12.

VI Systems debuts 56G NRZ VCSEL driver and TIA chips

Graph of simulated versus actual measured bandwidth of VCSEL driver IC

VI Systems has launched its first-generation 56Gb/s laser driver and amplifier chips designed for non-return-to-zero (NRZ) modulation in latency-critical optical communication links. The chips are designed to comply with the recently completed common electrical interface CEI-56G specification from the Optical Internet Working Forum (OIF), which specifies 56Gb/s NRZ signalling for very-short and ultra-short reach optical interconnects.

Smartoptics expands 100G QSFP28 transceiver family

The 100G QSFP28 transceiver remains a popular choice for intra-rack and data centre use and therefore is an important part of Smartoptics’ portfolio of compatible optical transceivers. Now Smartoptics has added four new models to its QSFP28 product range.

The SO-QSFP28-LR4-10L and SO-QSFP28-LR4-2L are direct-modulated laser (DML) diodes for 10km and 2km applications. The DML provides a cost-effective alternative to standard LR modules based on electroabsorption modulated lasers (EML), which are better suited to Ethernet-only traffic.

Qorvo launches PAM4 product family for data centres

Qorvo has introduced five new low-power four-level pulse amplitude modulation (PAM4) integrated circuits (ICs) aimed at delivering higher performance in data centre and client-side applications. The family of transimpedance amplifiers (TIAs) and drivers gives customers the broadest range of PAM4 options as their migrate their optical networks to 100G to 400G data rates.
