Optical communications component and module maker Avanex Corp of Fremont, CA, USA has broadened its tunable transponder portfolio by unveiling its PowerReach 2280 line of small-form-factor (SFF) tunable transponders with a live demonstration at this week’s OFC/NFOEC 2008 expo in San Diego, CA, USA. Applications include dispersion-compensated long-haul DWDM and metro links with a reach of up to 80km.

The SFF 10Gb/s transponder products offer the performance of Avanex’s large-format-factor (LFF) PowerReach 1280 but in a significantly smaller footprint, effectively allowing a doubling of line-card port density to help meet demand in metropolitan markets.

The PowerReach 2280 tunable transponder operates over all data rates from 9.9-11.3Gb/s and is housed in a 300-pin multi-source agreement (MSA) SFF package (3 inches x 2.2 inches) with standard electrical interfaces. The module integrates Avanex’s XS-10 lithium niobate modulator, is available with zero or negative chirp for transmission flexibility, and can be ordered with either APD (avalanche photodiode) or PIN receiver functionality.

“The PowerReach 2280 transponder delivers the benefits of a reduced form factor and best-in-class performance at reduced cost,” says Jeff Zack, general manager of Transmission products. In addition, it also comes with design features that provide highly reliable, long-reach transmission network solutions, he adds. These include programmable I 2C functions compatible with the 300-pin MSA I 2C specification edition 4.2, multi-rate jitter filtering, and transmit and receive options such as analog monitoring, adjustable performance parameters, and digital controls.

The PowerReach 2280 represents an example of Avanex’s aim to create highly cost-sensitive, smart and flexible products that enable the system provider to manage their operational expenses while scaling their application quickly, adds Senior VP of sales Scott Parker.
