CIENA announced several enhancements for its CoreStream long-haul DWDM transport platform, including:
- 1 GbE and 10GbE support — enabling direct interconnection at full line rates between core routers across long-haul and ultra long-haul distances. Ethernet interfaces are expected to be significantly cheaper than TDM interfaces. Product availability is expected by the end of the year. Pricing was not disclosed.
-
tunable transceivers (lasers) — which would reduce sparing costs on optical backbones by 90% while simplifying management with remote dynamic provisioning. CoreStream’s tunable transceivers are scheduled for release this summer.
-
next-generation integrated line amplifiers (ILAs) — which would provide cost savings by using a single amplifier for all applications, reducing the number of circuit packs to maintain and spare by 50%. The new ILAs also support transient suppression, a technique that allows the system to recover more quickly in the event of a transient caused by a fiber cut or network failure. Commercial release is expected this summer.
CIENA’s CoreStream DWDM offers both 50GHz and 25GHz channel spacing. With 25GHz channel spacing, the platform could support 192 10G wavelengths in the C-band alone.
