Oclaro (NASDAQ:OCLR) is making production shipments of its tunable SFP+ industrial temperature range (TSFP+ I-temp) DWDM transceiver. The transceiver is intended for cable companies deploying DOCSIS 3.1 to push fiber deeper into the hybrid fiber/coax (HFC) network to reach remote PHY nodes.

"Fully tunable DWDM laser technology is critical to enable large scale fiber deep deployment while minimizing operations cost and eliminating human errors," said Yves LeMaitre, chief strategy officer at Oclaro. "With tunable lasers capable of operating from -40 to 85 degrees C, we believe the days of analog optics or fixed WDM lasers are counted. 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 offering to include I-temp and follows the company's 10G TSFP+ C-temp and E-temp. The TSFP+ is vertically integrated through the use of Oclaro's in-house ILMZ chip and its TOSA and ROSA technology.
