Pirelli adds L-band coverage to tunable products

SEPTEMBER 5, 2007 — Pirelli Broadband Solutions will add full L-band coverage of 40 nm/100 channels to its tunable products, including lasers and transponders. Pirelli will display the L-band tunable offering at ECOC, September 16–20 in Berlin, at Booth 15093.

The L-band products are said to provide the same functionality as C-band items for reliability, simplified network configurations, and cost reduction. Inventory and lambdas count are also reduced, according to Pirelli, and adding L-band creates one interface for all wavelengths and flexibility in the optical layer.

Tunable offerings that will now host L-band functionality include the company's dynamically tunable laser, Telcordia GR-468-Core, which is qualified and hermetically sealed in a 26-pin-count butterfly package; the integrable tunable laser assembly (ITLA) for telecom networks integrating tunability; and Pirelli's 300-pin MSA transponders, available with NRZ, negative-chirp NRZ, Duobinary, and other optical-interface formats.

The 300-pin MSA transponders with L-band functionality reportedly can extend metro networks to 350+ km. Pirelli states that these solutions now suit metro networks in emerging markets, including Japan and Latin American countries.
