Oclaro Inc of San Jose, CA, USA (which provides components, modules and subsystems for optical communications) has announced production shipments of what is claimed to be the first fully tunable SFP+ industrial temperature range (TSFP+ I-temp) transceiver. Availability is said to represent a milestone for cable companies deploying the latest DOCSIS 3.1 standard, which pushes fiber installation much deeper into the hybrid fiber coax (HFC) network to reach next-generation Remote Phy nodes.
Cable networks need to offer best-in-class bandwidth to retain their customers and enable premium services, says Oclaro. With more than 50 million homes served by multi-service operators (MSOs) in the USA alone and up to 1 million new nodes, the deployment of 10G full-duplex per node over the next 4-5 years can only be achieved with products such as fully tunable DWDM lasers that are easy to install, configure and monitor.
“Fully tunable DWDM laser technology is critical to enable large-scale fiber deep deployment while minimizing operations cost and eliminating human errors,” says chief strategy officer Yves LeMaitre. “With tunable lasers capable of operating from -40°C to 85°C, we believe the days of analog optics or fixed WDM lasers are counted,” he adds. “Once you start using tunable products, the operational benefits such as automatic configuration and reduced sparing are just too great to go back to legacy optics.”
The TSFP+ is Oclaro’s latest product to include I-temp and follows the firm’s 10G TSFP+ C-temp (commercial temperature) and E-temp (extended temperature), which are both shipping now. The TSFP+ is vertically integrated through the use of Oclaro’s in-house ILMZ (integrated laser Mach-Zehnder) chip and its custom-designed transmitter optical sub-assembly (TOSA) and receiver optical sub-assembly (ROSA) technology. Due to the unique material composition of the ILMZ chip and custom tuning of thermal and electronic control components, the product is capable of operating from -40°C to 85°C. The TSFP+ I-temp is available now for volume production orders.
