Optical Transceivers
400G QSFP56-DD Transceivers
TORmem hardware
TORmem 400G QSFP56-DD (QSFP-DD) transceivers — the full 400GbE reach ladder from SR8 multimode and DR4/FR4/LR4 single-mode to ER4 and coherent ZR/ZR+ DCO, for switch fabric and metro links.
QSFP56-DD is the dominant 400GbE form factor, and this line spans its whole reach ladder: SR8 and SR4.2-BiDi on multimode; DR4/DR4+, 4×100G-LR, FR4, LR4, ER4L, and ER4 on single-mode; and QSFP56-DD-ZR/ZR+ DCO for coherent metro spans. Reaches run OM3/OM4/OM5 70–150 m up through SMF 2/10/30/40 km, with the coherent DCO reaching NDSF 120–500 km, on MPO-16, MPO-12, or duplex LC. Reach and connector are matched to your fabric — exact configuration confirmed at quote.
