Finisar demos CXP form factor for 40-100Gb/s, plus 16x FC SFP+ modules and 40Gb/s long-haul DWDM transponders

At this week's Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC 2009) in San Diego (24-26 March), Finisar Corp of Sunnyvale, CA, USA is demonstrating several new optical communication technologies, including a 120Gb/s parallel link, 16x Fiber Channel SFP+ transceiver, and 40Gb/s DWDM transponders using RZ-DQPSK modulation.

Finisar claims to be the first firm to showcase several new form factors capable of supporting 40Gb/s and 100Gb/s optical links over multi-mode or single-mode fiber optics. Specifically, it is showing a working 120Gb/s link over multi-mode fiber using a 12x10Gb/s parallel active optical cable which incorporates the new CXP pluggable form factor (the first public demonstration of a working CXP-based active optical cabling solution, targeted at InfiniBand and Ethernet data-center connectivity in high-performance computing, storage, and networking applications).

Finisar is also displaying the new 40Gb/s and 100Gb/s CFP pluggable transceiver form factor. CFP pluggable transceiver modules will be a key building block for next-generation 40Gb/s and 100Gb/s Ethernet routers and switches as well as for 40Gb/s and 100Gb/s telecom client interfaces, the firm says. Finisar is a founding member of the CFP multi-source agreement (MSA).

“Finisar's demonstration of a working 120Gb/s link using a 12x10Gb/s parallel active optical cable serves not only as an important proof-of-concept in enabling 100G line rates, but also demonstrates significant progress in optics technology,” claims VP of marketing Rafik Ward.

Also being shown at OFC is Finisar’s 300-pin MSA 40Gb/s DWDM optical transponder based on the RZ-DQPSK modulation format, which is designed to enable carriers to migrate their metro core, regional, and long-haul networks to 40Gb/s. Facilitating what is claimed to be the highest OSNR (optical signal to noise ratio) sensitivity on the market with superior PMD (polarization mode dispersion) tolerance, it is capable of supporting a large dynamic range of input optical power levels. The transponder can be designed into the same line-cards as Finisar's NRZ-DPSK 300-pin transponders as a compatible drop-in option, enabling DWDM system houses to achieve the highest performance available at 40G for OTU3 and OTU3e DWDM line cards, it is claimed.

Finisar is also showing a live 16x Fiber Channel (FC) short-wave SFP+ transceiver capable of operating over 150m of OM3 fiber. Currently being standardized by the INCITS T11 committee, 16x Fiber Channel is the next Fiber Channel data rate for storage-area networks. The SFP+ module is designed to meet the stringent requirements for reliability and link integrity required for mission-critical enterprise data-storage applications. The module operates at 14Gb/s with what is claimed to be exceptionally low power dissipation.
