Questions about this module
What is the difference between the 1.6T 2xDR4 and the 1.6T DR8?
Both deliver 1.6 Tb/s across 8 lanes over 500 m SMF via Dual MPO-12/APC. The 2xDR4 features an integrated closed-fin top heat sink and a 32 W maximum envelope. The DR8 features a closed-top housing for cold-plate or riding-heatsink cages, a 25 W maximum power rating, and documented breakout to 2 x 800G DR4 or 8 x 200G DR.
What optical connector does the 1.6T module use?
Both 1.6T OSFP224 modules use a Dual MPO-12/APC optical receptacle supporting 16 active single-mode fibers (8 Tx and 8 Rx).
How many lanes does the 1.6T module use, and what modulation?
The 1.6T 2xDR4 uses 8 lanes of 200G PAM4 (106.25 GBd) on both host electrical and optical interfaces. The 1.6T DR8 operates at 8 lanes of 212.5G PAM4.
Why is 1.6T our primary focus?
1.6T OSFP224 optical transceivers are the critical bottleneck for next-generation AI GPU clusters and remain in tight global supply across fewer than twenty optical manufacturers.
How much power does the 1.6T module consume?
The 1.6T 2xDR4 has a maximum power rating of 32 W. The low-power silicon-photonics 1.6T DR8 closed-top module is rated at 25 W or less. Both operate from a single 3.3 V supply.
What reach and fiber does the 1.6T module support?
Both 1.6T OSFP224 modules reach up to 500 m over parallel single-mode fiber (OS2 SMF).
What wavelength does the 1.6T module operate at?
The 1.6T 2xDR4 operates at a 1311 nm center wavelength within the 1304.5 to 1317.5 nm O-band window. The 1.6T DR8 is specified at 1310 nm.
What is a 1.6T OSFP224 optical transceiver?
It is our flagship pluggable optical transceiver in the OSFP224 form factor that converts 8 lanes of 200G-class electrical signals to optical signals at 1.6 Tb/s aggregate throughput. We produce two configurations: the 1.6T 2xDR4 (32 W max, integrated heat sink) and the 1.6T DR8 (25 W or less, closed-top).
