Chatsworth, CA –– Source Photonics Inc. (a subsidiary of MRV Communications (Nasdaq:MRVC)), a leading provider of optical communication products used in telecommunication systems and data communication networks, today announced the availability of the industry’s first 10Gb/s single fiber bidirectional SFP+ transceiver.

The single fiber bidirectional modules leverage Source Photonics’ expertise in low-cost bidirectional optics packaging combined with high speed optical device technology. The result is a fully SFF-8431 compliant SFP+ module that transmits and receives on a single fiber. The single-fiber, bidirectional interface improves the efficiency of telecommunication networks by reducing fiber cost and simplifying fiber management.

The optical specifications are modeled after the 10-km 10GBASE-LR interface, but utilize two different wavelengths in the 1.3um window for upstream and downstream transmission. Based on Source Photonics’ existing 10Gb/s SFP+ platform, the bidirectional modules have low power dissipation

<1W, which is consistent with high-density applications.

“This is a natural evolution for the 10Gb/s market”, said Emin Chou, Director of Product Development at Source Photonics. “As the 100BASE-BX and 1000BASE-BX single fiber interfaces have gained popularity in the past few years, going to a 10GBASE-BX type interface is a clear upgrade path for existing installations, and also opens up a whole new set of possible applications that previously did not exist in the 10Gb/s space.”

The bi-directional SFP+ complements Source Photonics’ broad portfolio of 10Gb/s products that includes SFP+ and XFP transceivers, and 300-pin transponders. The 10Gb/s bi-directional transceivers will also be offered in XFP form factor.
