LR4 CFP4 optical transceivers now in production says Oclaro

Oclaro, Inc. (NASDAQ: OCLR) says it is "ramping-up production" of an LR4 client-side optical transceiver in the CFP4 format. The optical modules are currently shipping to key customers, and the company expects to hit volume production in the second quarter of this year.

The CFP4 form factor offers a smaller footprint than its CFP and CFP2 predecessors, which is why Oclaro (and pretty much all of its competitors) has pursued development of such a module. Oclaro has designed the LR4 CFP4 for both 100GBASE-LR4 100 Gigabit Ethernet and OTU4 Optical Transport Network (OTN) applications. The company has used its proprietary indium phosphide (InP) 28G core electro-absorption modulated laser (EML) technology. At a typical 4 W, the optical transceiver demonstrates power consumption that Oclaro asserts is equal to or better than other CFP4 modules based on directly modulated laser (DML) technology.

The module also features Oclaro's Lens-Integrated PIN Photodiode (LIPD) array. The enabling devices are vertically integrated in Oclaro's wafer fab facility in Japan, which the company asserts provides both cost-effectiveness and shorter lead-times.

Oclaro says the 100G LR4 CFP4 is compliant with the IEEE 100GBASE-LR4 and ITU-T G.959.1 4I1-9D1F as well as the CFP4 MSA specifications. The company expects the module will find a home in high-end core router and packet-optical transport systems.
