Telecommunication systems need high data rate links for long range distance with few perturbations.  Systems which uses fiber optic link for data transmission are well designed for these applications.

This card includes one or many RISC Super-Scalar 64 bits processors. The total calculation power reaches 6,4 Gips (with the association of 16 cards of 400 Mips power each) and the total connexion capability is in this configuration 10 Gbits/s (16 cards with 622 Mbits/s option).<

Carte Lagoon I4 155 Opt

Many input ports are available on  Lagoon 4I xxx Opt.

The first port uses a VME bus which allows 122 Moctets/s rate transfer.

The second port integrates a VME port and in addition a high speed token bus which allows 320 Moctets/s synchronous rate transfer.

Four other serial ports are available.

A bi-directional optic port  allows 155 Mbits/s (622 Mbit/s in option) rate transfer . 

Each board implements a 2 MB (up to 32 MB) Zero Wait State memory and a 1 MB (up to 4 MB) buffer memory for communication on bus (VSB or HSTB)
