Micro-integrated coherent receiver from NeoPhotonics targets pluggable modules, line cards

NeoPhotonics Corp. (NYSE: NPTN) has extended its line of modules and components for 100G and 400G coherent transmission with a micro-integrated coherent receiver (Micro-ICR) designed to the OIF-DPC-MRX-02.0, Type 1 implementation agreement. Its small size makes it suitable for coherent CFP2 Analog Coherent Optics (CFP2-ACO) optical transceivers as well as high-density line cards, NeoPhotonics says.

The Micro-ICR is approximately one-quarter the size of the standard OIF 1.2 Type 1 ICR and one half the size of the OIF 1.2 Type 2 ICR. It offers what NeoPhotonics describes as "advanced features" for optical power monitoring and adjustment using variable optical attenuators. It is designed for use with a single laser for both the local oscillator and the transmitter.

This Micro-ICR joins the NeoPhotonics coherent lineup just as earlier members of the family are reaching production milestones. For example, the company's OIF 1.2 Type 2 Small Form Factor ICR (Type 2 ICR) and its micro-Integrable Tunable Laser Assembly (micro-ITLA) are now generally available and shipping to customers, NeoPhotonics says (see "NeoPhotonics expands suite of PIC-based products for coherent transmission"). Meanwhile, NeoPhotonics says it continues volume shipments and is increasing manufacturing capacity for its standard OIF 1.2 Type 1 ICR and its standard power ultra-narrow linewidth external cavity Micro-ITLA.

"We are excited to use our hybrid photonic integration technology in our Micro-ICR to take another significant step in reducing the size of 100G optical components and thus allow our customers to increase the density of their 100G and beyond line cards," said Tim Jenks, NeoPhotonics chairman and CEO. "We are increasing manufacturing capacity to meet market demand for our currently shipping 100G coherent optical components and plan to transition that capacity to our newer, higher density 100G and 400G products as demand grows."
