Ports 1 and 2 support distance extension at SDH side: FC100 supports 3000 km,
and FC200 supports1500 km.
Ports 1 and 2 support distance extension at client side: FC100 supports 40 km, and
FC200 supports 20 km.
Supports ESCON or DVB-ASI service from four ports.
All services are encapsulated in GFP-T mode compliant with ITU-T G.7041. The
services are mapped into VC-4, VC-4-Xc or VC-4-Xv.
2.2.5 Built-in WDM Technology
The OptiX OSN 7500 provides dual optical add/drop multiplex board MR2A/MR2C
and arbitrary rate wavelength conversion board LWX to realize built-in WDM
technology. Below are their characteristics.
The MR2A/MR2C can add or drop any two adjacent standard wavelengths (with
spacing being 100 GHz) in compliance with ITU-T Recommendation G.694.1. The
operating wavelength range is 1535.82 nm–1560.61 nm.
The MR2A/MR2C can be used as an OTM to add/drop two wavelengths and
concatenation of two MR2A/MR2Cs can function as an OTM to add/drop four
wavelengths.
The MR2A/MR2C can work with the LWX to function as an OADM to add/drop two
wavelengths.
The LWX supports the conversion between client signaling wavelength and ITU-T
G.692 compliant standard wavelength and supports transparent transmission of
signals.
Provide 3R function to added/dropped client signals (10 Mbit/s–2.7 Gbit/s),
implement clock recovery and monitor the transmission rate.
Provide two types of LWX board, one is single-fed single receiving and the other is
dual-fed selective receiving.
The dual-fed selective receiving LWX board supports intra-board protection with
protection switching time less than 50ms.
The single-fed single receiving LWX board supports 1+1 inter-board protection with
protection switching time less than 50ms.
2.2.6 Service Access Capability
The capacity of services that the OptiX OSN 7500 can access varies with the type and
quantity of the configured boards. Table 2-2 lists the maximum capacity of the OptiX
OSN 7500 for accessing different services.
