OMS 3250

OMS3250Product DescriptionThe following table summarises the maximum capacity for each variant of the card:Card variantCapacity in OMS3250Slot16 SPF sockets, Multiport 16 x STM-116 SPF sockets, Multirate 4 x STM-16or 16 x STM-4or 12 x STM-1or a mix of STM-1/4/168 SPF sockets, Multiport 8 x STM-48 SPF sockets, Multirate 2 x STM-16or 8 x STM-4or 6 x STM-1or a mix of STM-1/4/164 SPF sockets, Multiport 4 x STM-164 SPF sockets, Multirate 4 x STM-16or 4 x STM-4or a mix of STM-4/16Table 4: Port capacities for each variant of Multirate cardThe card variants support many combinations of mixed STM-1, STM-4 and STM-16 ports. Forexample, some of the many possible configurations for the 16 port MULTIRATE card equippedin an OMS3250 slot are listed below:• 2 x STM-16 + 2 x STM-4 + 12 x STM-1• 1 x STM-16 + 6 x STM-4 + 9 x STM-1• 4 x STM-4 + 12 x STM-1Marconi Multirate card represents the most flexible and cost-effective solution to provide STM-1/4/16 services. For instance, in a node where a low number of different STM-1el/STM-1opt/4/16 signals is required, the user is not forced to equip a card for each type of signal, withthe risk to have multiple unused ports. The user can decide to use a single Multirate card tosupport the required mixed configuration and equip each port as it is required.3.4.2 Gigabit Ethernet cardThe Gigabit Ethernet cards provide point to point transport of data traffic over SDH deliveredover industry standard Gigabit Ethernet (optical) interfaces.The Gigabit Ethernet cards are available as tributary cards for the OMS3250.Key points of the Gigabit Ethernet cards are:• 4 x 1000BASE-SX, LX, LH and ZX interfaces (provided as SFP optical modules on tributarycard) as per IEEE 802.3:- Short 850nm Multi-Mode Fibre: 500m- Intermediate 1310nm Single Mode Fibre: up to 5km- Long 1310nm Single Mode Fibre: up to 10kmIssue 1 Copyright – Refer to Page 2 Page 23 of 74
