Yahara - S10123, S10124, S10126
As with the S10123 device, the S10124 also supports two 10G
MACs for full 10GbE traffic monitoring on both the Transmit
and Receive datapaths of the device. In addition, the S10124
device also provides OTU-2 and WIS (OC-192/STM-64) Drop/
Insert ports for out-of-band overhead monitoring and
provisioing capability.
Via the S10124/S10126’s two serial 10G interfaces and SFI4.1
interface, the S10124/S10126 devices are also ideally suited for
ODU-2 to OTU-2 regenerator applications.
Serial 10G Interface(s)
•
YAHARA(s) 10G serial line interface(s) supports the following
LAN/WAN/OTN Frequencies/Protocols
As with the S10123 device, all major blocks within S10124
device can be provisionally bypassed, including the GFP-T and
GFP-F mappers, the WIS Frame Generator/Termination blocks,
and the GFEC/EFEC Frame Generators/Termination and
Encoder/Decoder blocks.

8G Fibre Channel (8.5Gb/s)
10GbE LAN (10.3Gb/s)
10G Fibre Channel (10.51875 Gb/s)
OC-192/STM-64/WAN (9.954 Gb/s)
Standard OTU-2 (10.709Gb/s)
The S10126 device supports a dedicated serial 10G Client
inteface and a dedicated serial 10G Line inteface. It is ideal for
10x10G to 100G muxponder applications, as the GMP mapping
mode allows for the synchronizing of asynchronous ODU-2s to
a common OTU-4 clock, resulting in a dramatically reduced
number of external PLLs required. In addition, the S10126
supports all of the other mapping modes of the S10123 and
S10124 devices, as well as the two 10G MACs for full 10GbE
traffic monitoring, and OTU-2 and WIS Drop/Insert ports for
out-of-band overhead monitoring and provisioning capability.
Overclocked 10GbE to OTU-2 (11.096Gb/s and 11.049Gb/s)
Overclocked 10G FC to OTU-2 (11.32Gb/s and 11.27Gb/s)
Fully integrated CMU, CDR and SERDES
The lower Line Rates modes are associated with the fixed stuff
byte columns being used for user data.
XAUI/SFI4.2/SFI-5s System/Backplane Interface
YAHARA’s System/Backplane Interface is XAUI/SFI4.2/SFI-5s
compliant
•
•
In the XAUI mode, it supports 4 x [3.125Gb/s] in 10GbE oper-
ation] or 4 x [3.1875 in 10G Fibre Channel operation]
One of the key features of the YAHARA device(s) is its Forward
Error Correction capabilities. The YAHARA device(s) support
the ITU G.790 (GFEC) standard and AMCC’s widely adopted
enhanced FEC (eFEC) to enable long haul transmission by
compensating for the optical noise in the optical link. Also,
YAHARA’s XFI serial 10G interfaces have built in Electronic
Dispersion Compensation (EDC) that mitigates chromatic
dispersion to enable longer transmission distances.
•
•
•
In the SFI4.2 mode it supports 4 x [2.19Gb/s] to [2.94Gb/s]
In the SFI-5s mode it supports 5 x [2.125Gb/s] to [2.85Gb/s]

Clocking
•
Flexible clocking configurations for Carrier Ethernet and
Transport applications.
With the S10123 device, G.709 FEC or eFEC can be provisionally
appended to the outgoing ODU-2 line signal to produce a jitter
compliant OTU-2 serial 10Gb/s output signal. In the reverse
direction, the S10123 can receive a 10G OTU-2 signal on the
serial 10Gb/s Line receive input, terminate the GFEC/eFEC,
perform OTU-2 frame monitoring, and send the ODU-2 signal
directly to the System output interface. The 10G MAC, GFP and
WIS blocks can be bypassed in both the transmit/receive
direction.

GHz
With the S10124 and S10126 device, in addition to terminating
and generating G.709/eFEC OTU-2 signals on the Line side, the
S10124 and S10126 devices can also generate G.709 FEC
signals on the outgoing ODU-2 Client signal to produce a jitter
compliant OTU-2 serial 10Gb/s output Client signal. In the
reverse direction, the S10124/S10126’s Client signal can
receive a 10G OTU-2 signal on the serial 10Gb/s Line RX receive
input, terminate the GFEC, perform OTU-2 frame monitoring,
and send the ODU-2 signal directly to the Line Side for GFEC/
GFEC or GFEC/eFEC regneration, or to the System output
interface. Again, the 10G MAC, GFP and WIS blocks can be
bypassed in both the transmit/receive direction.

G.709 ODU-2 Synchronous and Asynchronous Mapping
•

The S10124 also supports an SFI4.1 interface that can be used
on either the Client or Line interface. The SFI4.1 interface is
ideal for supporting fully tuneable laser MSA Optic Modules.
