PMA32 – Features

PMA-32 uses 100 GHz spaced DWDM RX and TX line interfaces on single mode fiber

It multiplexes/demultiplexes up to 32 optical channels in the range between 192.1 THz (1560 nm) and 195.2 THz (1535 nm)

A 33th wavelength (SCh-Oh, Supervisory Channel, 1510 nm) carries Section Overheads in a 2Mbps channel.

SCh-Oh provides node to node communication, monitoring and remote configuration

Supported tributary interfaces:• 155 Mbps (STM-1/OC-3)• 622 Mbps (STM-4/OC-12)• 1.25 Mbps (Gigabit Ethernet)• 2.5 Gbps (STM-16/OC-48)• 10 Gbps (STM-64/OC-192)
