Oclaro unveils new micro-iTLA and InP coherent receiver platform

The receivers employ indium phosphide integration technology to deliver reliability and are one of the first receiver solutions to package a signal power monitor diode

Oclaro has strengthened its 40 Gbps and 100 Gbps coherent optical portfolio with the introduction of a new micro-iTLA and 40 Gbps PM-BPSK modulator.

The company has also announced the volume production of its 40 Gbps and 100 Gbps PM-DPSK modulators and its coherent receiver platform. 

By providing an expansive line of both coherent components and module solutions, Oclaro is enabling its customers to quickly and cost-effectively deliver next generation network equipment that provides scalable and flexible future proof architectures.

These products will be on display at the OFC/NFOEC show in the Oclaro booths #1957 and #2058.

Oclaro says it is well positioned to establish a leadership position in the high-bit rate 40 Gbps and 100 Gbps coherent markets, which analyst firm Ovum predicts to grow from $360M in 2011 to more than $2.1B in 2015. Coherent detection is widely considered the leading technology for enabling higher optical transmission speeds such as 100 Gbps because it delivers the scalability and flexibility needed for transmitting more bandwidth cost-efficiently over fibre optic networks.

As a result, network equipment manufacturers are rapidly embracing this detection format and are installing 40 Gbps coherent networks as a stepping stone to 100 Gbps or going directly to deploying 100 Gbps networks for long-term sustainability.

"PM-QPSK Modulators, coherent receivers and narrow line-width micro-iTLAs are the complete set of optical components that customers need for deploying high-speed coherent 40 Gbps and 100 Gbps systems," says Robert Blum, Director of Product Marketing for the Oclaro Photonic Components Business Unit.

"As a one-stop-shop supplier for all these critical pieces of the network, Oclaro is enabling customers to save a significant amount of development time, ensure the highest level of integration on their line-cards, and deliver the network architecture that service providers need for long-term success," continues Blum.

At the OFC/NFOEC show, Oclaro is introducing a new 40 Gbps PM-BPSK modulator targeted for ultra long haul transmission systems such as those used in submarine applications. The new modulator is sampling today with production scheduled to start in June 2012.

The firm's products for all 40 Gbps modulation formats allows customers to maintain their existing 10 Gbps networks while also gaining the flexibility to upgrade to higher-speed coherent networks in the future.

The firm's coherent receiver platform has completed qualification and is entering volume production. The receivers are more than 50 percent smaller than the 100G footprint defined by the OIF - while also providing an option to maintain full compliancy with the OIF standard. 

The receivers utilise Oclaro's indium phosphide integration technology to deliver reliability and are one of the first receiver solutions to package a signal power monitor diode. In the past, customers needed to add a discrete monitor photodiode onto their line cards. By integrating this functionality directly into the receiver, customers can now save valuable line card space, while also lowering costs and reducing development time.

The new micro-iTLA delivers the small footprint, optical power, narrow linewidth and low power consumption needed to transmit at higher data rates across the network. The micro-iTLA delivers a 3 times reduction in size over standard iTLA products while also meeting the requirements for advanced coherent applications.

Oclaro worked with other laser and network equipment manufacturers through the OIF to define a micro-iTLA Multi Source Agreement specification in 2011, specifically defining reductions in footprint and height. With its new micro-iTLA, Oclaro also achieved reductions in power consumption, which will allow its customers to produce efficient designs in small form factors. 

The micro-iTLA leverages upon Oclaro's proven tunable TOSA packaging and solid state tuning based InP DS-DBR chip technologies, of which well over 300,000 tunable lasers have now been deployed. Oclaro's InP capabilities enable its customers to reduce power consumption and space constraints whilst offering advanced performance.

Oclaro's micro-iTLA is scheduled to ship to key customers during Q2 of 2012.
