Components and Subsystems

II‐VI Photonics, a provider of pump laser modules for terrestrial and submarine optical networks, has announced the general availability of its high-power, 2 x 810mW, dual 980nm pump laser module.

The new dual-chip, dual-output, pump laser modules enable designers to replace two laser modules with one. Housed within the compact 10-pin mini-butterfly package, they consume less electrical power, generate less heat and enable significant reductions in the size of high-performance, multi-stage optical amplifier designs. 

ProLabs, a provider of compatible network connectivity products, has launched of a new range of optical transceivers that are designed to work with Cisco, Juniper and Arista platforms.

Whilst the functionality is similar to other optical transceivers, the EEPROM code that is loaded into a ProLabs multicode transceiver is compatible with three vendors instead of just one.

Scottish company Optoscribe has added an ultra-low crosstalk option to its 3D Optofan series of multicore fibre fanout cables.

Designed for applications in the field of spatial division multiplexing (SDM), these cables connect the multiple cores in a multi-core fibres to separate singlemode fibres. They are a key component in the development of such systems, which offer the potential for extremely high data rates.

Menara Networks has started volume shipments of its flagship 100G CFP pluggable optical module using direct detection for metro and data centre interconnection.

Menara’s 100G CFP module is based on the dispersion-tolerant optical duo-binary modulation format (ODB), which provides extended reach of up to 300km. This technology allows existing 10G DWDM infrastructure to be upgraded to 100G without the prohibitive cost, footprint and power of a coherent solution, the company says.

Semiconductor products supplier M/A-COM Technology Solutions has announced the new wideband MAOM-003427, a quad-channel linear modulator driver with 46-Gbaud capability to support next generation 200G and 400G applications.

This addition to MACOM’s extensive portfolio of driver solutions for optical infrastructure enables system designers to address higher baud rate applications with lower-cost surface mount technology.

Having demonstrated a 40G version back at OFC in March, Finisar used ECOC 2015 to show off the world’s first 100G QSFP28 SWDM4 module operating over multimode fibre.

Paving the way for next-generation systems at 400G and beyond, NeoPhotonics has announced a suite of products and technologies designed to support 400G optical transport across multiple network segments, including long haul, metro and data centre interconnect (DCI).

The indium-phosphide-based, high-bandwidth, dual-polarisation IQ modulator from TeraXion can enable increased spectral efficiency and reach in next-generation, single-carrier transmission systems at speeds beyond 100Gb/s, the company claims.

“Our commercially available indium phosphide modulators are ready to meet system requirements for 100Gb/s and upcoming advanced modulation formats,” stated Ian Woods, vice president of high-speed photonic components at TeraXion.

Phoenix Photonics, a developer and supplier of components for few mode fibre (FMF), plans to demonstrate its latest product – the cladding-pumped few-mode erbium-doped fibre amplifier (FM-EDFA) – at ECOC 2015.

The product adds to the company’s product range targeted at the space division multiplexing (SDM) market, which exploits new types of optical fibre. It complements the core-pumped amplifier that was released in 2014, providing different options for researchers investigating mode-division multiplexing (MDM) transmission using few mode fibres.  

Oclaro has announced initial sampling of a 100G QSFP28 client-side transceiver that is ideally suited for 100G interconnections between data centre switches in addition to interfaces in high-end routers and packet-optical transport systems.

The new module meets both the CWDM4 MSA and CLR4 Alliance optical interface specifications, as well as the IEEE 802.3bm CAUI-4 electrical interface specification, in a single design that features low power consumption of 3.5W.
