Finisar and Sumitomo in transceiver pact
Finisar Corp and Sumitomo Electric Industries have signed a crosslicensing agreement covering certain intellectual properties in fibre-optic transceivers that both companies own.
Finisar Corp and Sumitomo Electric Industries (SEI) have signed a crosslicensing agreement covering certain intellectual properties in fibre-optic transceivers that both companies own The agreement includes several issued or pending Finisar patents that apply to small form factor pluggable (SFP) transceiver modules, which are designed for high-speed communication applications of up to OC-48 speeds

Laserwire uses fibre optic technology for the transmission of data while reducing the weight, density and power consumption of copper wire.

The Longwave fibre channel SFP+ 1310nm transceivers support 1.4km and 10km transmission over single-mode fibre.
The small size of the SFP allows designers to fit twice the number of modules in the same circuit board space.
An additional peripheral interface controller provides digital diagnostics functions for remote monitoring, in addition to the built-in serial ID information.
These "smart" diagnostics and monitoring functions are being standardised by the SFF Committee under document SFF-8472, and provide calibrated, absolute real time measurements of the laser bias current, the transmitted optical power, the received optical power, and the internal transceiver temperature and supply voltage.
They allow datacomms and telecommunications companies to implement reliable performance monitoring in a very accurate and cost-effective way.
The Finisar patents licensed to Sumitomo cover this digital diagnostics technology, as well as a sliding SFP module latching mechanism.
"In the need to meet rapidly growing demand for more functions in the smaller form factor, SFP is a key technology for equipment suppliers", explains SEI's Director and General Manager of Photo-Electron Products Division, Shuzo Suzuki.
"The agreement allows us both to rapidly expand our offerings to better meet the needs of our customers".
In return for the digital diagnostics technology, SEI granted Finisar access to several of Sumitomo's leading patents in the optical transceiver field.
"We are very pleased to be able to provide our customers with a more comprehensive range of options in optical transceiver modules", said Dick Woodrow, Vice President of Sales and Marketing at Finisar.
"This agreement leverages both companies' strengths in order to satisfy the increasing market demand for this type of technology", he added.
Specific terms of the agreement have not been disclosed.
