OTS 4000 System

The StrataLight OTS-4000 series optical terminal subsystem is an industry-compliant shelf-level product that occupies one third of a standard seven-foot equipment rack and supports eight hot-swappable line cards, each with 40 Gbps total capacity. The OTS-4000 chassis supports redundant DC power feeds and provides full redundancy of all common equipment.

The 40 Gbps optical outputs of the OTS-4000 series line cards operate on 50 GHz or 100 GHz ITU grid channel spacing. Thanks to its narrow spectral width and tolerance to chromatic dispersion and optical filter distortion, StrataLight's 40 Gbps signal can be retrofitted into existing 10 Gbps DWDM optical channels, enabling Multi-Haul (simultaneous 10Gbps and 40Gbps on the same fiber) without the need for special 40 Gbps sub-bands. This compatibility with existing fiber types and 10 Gbps transport line systems effectively quadruples the capacity remaining on the original 10 Gbps DWDM span, and significantly delays fiber exhaust and the expenditure involved with lighting incremental fiber. OTS-4000 is scalable in single 40 Gbps channel increments, and provides a carrier with an immediate reduction in transport costs. StrataLight's 40 Gbps transponder technology supports long-haul transmission using EDFA-only or ultra long-haul using Raman-assisted amplification.

To facilitate flexible integration into existing NMS environments the OTS-4000 employs a Java™ component model as its common management interface and supports a full range of FCAPS features. Standard interfaces include Web, XML, and SNMP.

The OTS-4000 terminal subsystem consists of the following components:
