TruePulse would like to purchase 130-6404-930 and 130-6405-930 circuit packs for the Ciena CoreStream long-haul optical transport platform, or alternately known as the MultiWave Sentry 1600.
The 130-6404-930, HECI code WMOTBAB, is a Ciena CoreStream Module Assembly G.709 XCVR with SR-1 Client Interface, Band 4
The 130-6405-930, HECI code WMOTBAC, is a Ciena CoreStream Module Assembly G.709 XCVR with SR-1 Client Interface, Band 5
The ITU-T Recommendation G.709 Interfaces for the Optical Transport Network (OTN) describes a means of communicating data over an optical network. It is a standardized method for transparent transport of services over optical wavelengths in DWDM systems. It is also known as Optical Transport Hierarchy (OTH) standard.
The G.709 OTUk signal is positioned as a server layer signal for various client signals, e.g. SDH/SONET, ATM, IP, Ethernet, Fibre Channel and OTN ODUk (where k=0, 1, 2, 2e, 3, 3e2, 4 or flex).
The frame structure defined in G.709 consists of four portions:
- OPUk is the area in which payload is mapped.
- ODUk contains the OPUk with additional overhead bytes (e.g. TTI, BIP8, GCC1/2, TCM etc.).
- OTUk is the section and includes framing, TTI, BIP8 and GCC0 bytes.
- FEC – The standard Forward Error Correction Code
G.709 offers advanced OAM&P capabilities such as Tandem Connection Monitoring (TCM), End to End performance monitoring, connectivity monitoring, signal quality supervision and General Communication Channel (GCC).
In addition to the 130-6404-930 and 130-6405-930, TruePulse is interested in other Ciena CoreStream modules too. In fact, we are interested in Ciena modules for many other platforms, including the Optera Connect DX, the 6500, the OM 5100 / 5200 and the DN4100.
