Application scope

Match the module to the network role

Edge network DCO

QSFP28 DCO supports 100G transmission up to 120km, with up to 80km unamplified and optional extension to 300km. It supports 100GE or OTU4 host signals.

Full C-band tunableDP-DQPSK0 to 70°C / -40 to 85°C

Metro and long-haul DWDM

CFP2-DCO variants support 100G/200G and 200G/400G single-wavelength DWDM transmission over SMF, with the supplied reach figures shown below.

Signal and interface support

Designed around the supplied host and line interfaces

Host / client side

Depending on model: 100GE, 200GE, 400GE, 800GE, OTU4, OTUC2, OTUCn, 2×100GE, or 1×400GE.

Line side

Coherent C-band interfaces with DP-QPSK, DP-DQPSK, DP-8QAM, DP-16QAM, or MPCS modulation as specified by each model.

Management and connector
