Cisco STM64 SH 1550 1 CKT SC REFURB

The Cisco STM-64 Fixed Optics Card provides a single XFP-based pluggable optics module with greater benefits than the fixed optics cards it replaces. It provides multiple-reach capabilities including intraoffice (IH), short-haul (SH), long-haul (LH), and ITU DWDM frequencies. Additionally, the I1-only card provides a cost-effective, fixed IH configuration to support first cost-sensitive installations where flexibility is not paramount. It offers more cost-effective sparing of XFPs versus fixed card alternatives, making it suitable for all metro applications between central offices, colocation offices, or enterprise and campus facilities with span lengths from 2 km to 80 km.
