The TM-6DXFPF and TM-6DXFPF 10Gbps with Forward Error Correction (FEC) transponders are single long slot modules usable in the LD1600, LD1600L and LD400L LambdaDriver chassis, that convert the “gray” wavelength of a 10 Gbps terminal equipment interface to ITU-T grid DWDM wavelength enabling its transport via the LambdaDriver® Optical Transport System (DWDM multiplexer, OADM etc.).

The TM-6DXFPF modules support OC-192/STM-64 and 10 GE protocols with 3R signal conditioning.

A key feature of the modules is the support of the G.709 FEC standard protocol as well as Enhanced FEC (EFEC) protocol with better error correction performance. The FEC/EFEC mode is user selectable via management and set to EFEC by default.
The error-correction performance significantly extends the overall distance reach of the link for very low BER performance.

For 10GE and OC192/STM-64 the G.709 digital wrapper technology is used to transparently pass any type of payload.

Standard performance monitoring is supported for end-to-end SONET/SDH terminated signals providing at each receive side the relevant conditions and alarms as per ITU G.783, GR-474 standard definitions. Statistics for current 15 minutes interval and up to 96 previous intervals can be viewed.

For 10GE traffic, performance parameters as defined by the RFC 2819 (RMON), MIB2 and IfMib extensions are supported. In addition, the extensive information provided by the G.709 monitoring allows for detailed performance analysis such as BER, statistics, etc.
Line and Diagnostic Loop-back functionality is supported and provides an essential tool for troubleshooting and maintenance operations in a live network. The Diagnostic loop-back function checks the integrity of the internal ports circuitry while the Line loop-back is used to check the fiber connections integrity. The Line Loop-back and the Diagnostic Loop-back are available for Access (Client) ports.

The Link Integrity Notification (LIN) function allows the terminal equipment to detect the link failure in the path between the two terminal equipment units regardless of the location of the failure. The link failure is propagated throughout the network until it reaches the terminal equipment, by disabling the transmission immediately upon failure detection at the opposite port of the transponder. The LIN function is turned off by the management interface (for the case of SONET/SDH signals etc.).
