Spider : 10G multi-channel & multi-protocol mapper

Precise-ITC offers a dynamically reconfigurable SDH/OTN Nx10G multi-lane multi-protocol transponder/mapper FPGA solution for 10GE or FC1200 clients. The Nx10G FPGA is a single chip multi-lane solution for multi-protocol transponder/mapper (e.g. 10x10GE to OTN, 20xFC1200 to OTN, 40x10GE to OTN, etc).  Each lane is individually configurable through an easy to use Software Application Programming Interface (API) or customizable software driver.

AES-GCM encryption is optional add-on feature to further enhance the power of spider SOC.

If the SOC is put on FPGA, the transponder/mapper is fully customizable and tailored to individual’s need.

The N x 10G Transponder solution provides a complete solution for up to N lanes of multiple client data transport to a SDH/SONET/Ethernet WIS or OTN network. Each lane is individually, dynamically re-configurable through a software API. On the client side, the transponder connects directly to a XFP or SFP+ or XAUI interface. The client signal is transcoded and mapped depending on the desired application.

Existing 10G transponder/mapper solutions offer 1 to 4 lanes per chip. Our FPGA solution can offer much higher lane (port) density per chip, typically 4, 8, 10, 12, 16, 20, 32, 40 or higher (depending on FPGAs). As a result of higher port density, better power efficiency and cost effectiveness can be obtained.

Supported Lane Configurations

The following shows the supported configuration of any individual lane of transponder can be configured for different applications:

• Lane Type 1 : CBR10G/SONET/SDH -> BMP/AMP/GMP -> OTU2
• Lane Type 2a : 10GE -> PMA/PCS-R -> OTU2e
• Lane Type 2b : 10GE -> XAUI -> XGXS -> PCS-R -> OTU2e
• Lane Type 3 : 10GE -> PMA /PCS-R -> Ethernet Mac -> GFP-F -> OTU2
• Lane Type 4 : FC1200 -> PMA/PCS-R -> TTT -> GFP-F -> OTU2e
• Lane Type 5 : 10GE -> PMA/PCS-R -> WIS/STM-64c/OC-192c
• Lane Type 6 : Customer specific mapping


Since each lane is independent and can be dynamically re-configured to perform a different function without affecting the other lanes in mission, the following illustrate some examples on lane mixes for 20x10G application.

•    10x10GE to OTU2e + 5xFC1200 to OTU2e + 5x10GE-WIS
•    Or 20xFC1200 to OTU2e
•    Or 10xFC1200 to OTU2e + 10x10GE to OTU2 via GFP-F
•    Any combination of lane configurations fit custmer’s need
