Optical modules produce 220m error-free
link
Optical modules offer a robust mechanical bail-latch design, excellent optical and electrical performance, and Finisar's patented digital diagnostics capability.
Finisar, a supplier of optical-fibre components and subsystems for datacom, and telecom applications, has demonstrated several new modules at the Optical Fibre Conference in Anaheim, California The demonstrations highlight key optics technologies including 10Gbit/s SFP+ LRM (Small Form-Factor Pluggable Long Reach Multimode), GPON (Gigabit Passive Optical Network) transceivers for Optical Line Termination (OLT) and Optical Network Unit (ONU) applications, and Extended Reach DWDM (Dense Wavelength Division Multiplexing) SFP transceivers

Transceiver cuts DWDM cost, size and power budgets
The Finisar FTR-1631 transceiver offers DWDM transport with dramatically lower power and cost in a standard pluggable GBIC package.
Using Finisar's low-power-dissipation 10Gbit/s SFP+ LRM modules, Finisar will demonstrate an error-free link over 220m of legacy multimode fibre.
These modules achieve the 220m distance using electronic dispersion compensation (EDC) solutions from Aeluros and Vitesse.
The power consumption is less than 1W.

Fibre-optic transceivers roll off the line
Finisar has made its first customer delivery of XFP 10Gbit/s optical transceivers.
These modules also offer a robust mechanical bail-latch design, excellent optical and electrical performance, and Finisar's patented digital diagnostics capability.
SFP+ is a new mechanical form factor highly anticipated by Ethernet and storage equipment vendors who want to be able to exploit the benefits of high density and low power consumption.
LRM is the latest optical reach for SFP+ supported by Finisar, in addition to existing 10Gbit/s Ethernet short reach (SR) and long reach (LR) product lines.
With this new module, Finisar now offers a "triple-plus solution" - 10Gbit/s SFP+ SR, LR, and LRM - supporting the three key optical reaches for datacom and storage equipment vendors in the SFP+ form factor.
"Finisar's SFP+ demonstration is an important milestone", says Rafik Ward, Director of Marketing, Finisar.
"We believe the 10Gbit/s SFP+ LRM module fits a rapidly emerging market need and the interoperability we've shown with our LRM product helps give designers the confidence they need to design SFP+ into their next generation networking equipment".
"Aeluros's EDC technology is now mature enough to enable the adoption of SFP+ based applications across a number of different market segments", says Don Stark, Vice President of Engineering for Aeluros.
"We have thoroughly tested our EDC devices over a variety of test conditions including CSRS tests defined in the IEEE802.3aq standard, to verify compatibility with SFP+ transceivers from vendors like Finisar".
According to Vitesse Director of Marketing, Richard Interrante, "Vitesse's production-ready EDC technology is enabling vendors like Finisar to provide SFP+ LRM optical solutions to their customers".
"We are proud to be associated with this demonstration of interoperability at OFC".
Finisar has also set its sights on providing modules for the fast-growing GPON OLT and ONU market, using its expertise in quality and high volume manufacturing to ensure a reliable source to its customers that can meet growing GPON demand.
In addition to offering Finisar's signature advanced diagnostic capabilities, the Finisar GPON modules are specifically designed for high-volume manufacturing, a critical factor to successful PON deployment.
These modules are part of a complete and broad portfolio of products targeting telecom applications in the access, metro and transport networks that leverage Finisar's experience in vertical integration.
Finisar will also demonstrate Extended Reach DWDM SFP modules which offer network designers the opportunity to reduce the number of amplifiers and dispersion compensation modules used in a network.
This reduction creates instant cost savings in new metro network deployments as well as increased reliability by eliminating points of failure.
In the demo, error-free data is transmitted over 2 C-band DWDM SFP's on different wavelengths over 160km of fibre making use of an Erbium Doped fibre Amplifier (EDFA) while avoiding the need for dispersion compensation in the link.
