FRANKFURT -- Fujitsu Microelectronics Europe (FME) and AimCom announce an add/drop multiplexer on a chip (ADM-on-a-chip) that will enable the creation of reliable, leading-edge networks. The MB87Q2060 integrates all the features that are critical for applications in metro and access networks with line rates up to 2.5Gbps.

The new device supports grooming, automatic protection switching and performance monitoring for more than 3000 VT1.5 or VC12 channels. The high-density VT/VC device also features line and backplane framers, cross connects at VT1.5, VC12, VC3, STS1 and VC4. With this new chip, Telecom equipment manufacturers can now build OC-48/STM-16 multi-service provisioning platforms (MSPP) or optical edge devices (OED) in a compact 1 RU high chassis.

The MB87Q2060 provides 18 multi-rate line interfaces and 16 backplane interfaces. The line ports support up to OC-48/STM-16 rate and have integrated clock data recovery to allow direct connection to hot pluggable SFP modules. The backplane ports are OIF TFI-5 compatible or are operated at 622Mbps. Four E1/DS1 ports are integrated and an 8-bit Telecom bus at 19 or 77MHz enables connection to external mapper devices. Furthermore, the device integrates a system clock to create G.813 SEC or GR-1244 Stratum-3 network element timing.

The on-chip line interfaces allow creation of a full-featured OC-48/STM-16 ring add/drop multiplexer or protected terminal in a single device. Alternatively, a carrier-class multiservice solution can be built when the backplane ports of two MB87Q2060s are connected to various service cards. Such cards can be fitted with, for example, FME's ETHOS Gigabit Ethernet mapper or AimCom's E1 PDH mapper device to provide the key elements of a Multiservice Provisioning Platform.

Mark Ellins, Director of Communications Business Unit at FME commented, "The integrated grooming and hardware-based protection switching at VC12 level are critical features when aggregating traffic on low-fill STM-1 links from optical access devices. The success of Ethernet services, mapped via GFP and virtual concatenation in VC12s or VC3s at the access nodes, now mandates high-density grooming and switching in the metro and core nodes of the network. Similarly, in wireless networks, we are seeing a lot of E1 backhaul via STM-1, but these STM-1 links are only partially filled. The non-blocking cross connects, and end-to-end performance monitoring per VC12 on the MB87Q2060 are the mandatory features needed for these applications."
