400GBASE-DR4 OSFP Optical Module: 400G-OSFP-500

The 400G-OSFP-500 is a 400GBASE-DR4 transceiver in the OSFP form factor for parallel single-mode fiber links up to 500 meters. It implements IEEE 802.3bs Clause 124, four parallel PAM4 lanes at a single wavelength near 1310nm, for a maximum data rate of 425 Gbps.

The host electrical interface is 400GAUI-8, eight lanes of 53.125 Gbps PAM4 gearboxed internally to the four 1310nm optical lanes, distinct from the native 400GAUI-4 interface used on EDGE's OSFP112-class 400G modules, which run no gearbox stage. Confirm which interface the target host port expects before ordering.

Average launch power per lane is −2.9 to 4 dBm, average receiver sensitivity per lane is −5.9 to 4 dBm, and receiver overload is 5 dBm. Minimum optical budget (OMA) is 3.6 dB, average link budget is 3 dB over 500 meters. The transmitter is a CW laser with a 3.5 dB minimum extinction ratio; the receiver is a PIN photodiode with DDM, CDR, and host side RS-FEC (KP4, RS(544,514)) support per the IEEE 802.3bs 400G PAM4 path.

Media connectivity is an MTP/MPO-12 APC connector with 8 fibers across the 4 transmit and 4 receive lanes. MPO/APC does not mate with MPO/UPC, so any trunk or breakout cable must also be APC terminated. The module's four parallel 1310nm lanes break out through a single MPO-12 to 4x LC harness into four independent 100GBASE-DR links, one lane per link, each up to 500 meters.

Operating temperature is 0 to 70C, storage is −40 to 85C at 5 to 85 percent relative humidity, and power draw is bounded at 12W on 3.3V. The finned top module carries CE, RoHS, Class 1 FDA and IEC 60825-1 laser safety compliance, and follows IEEE 802.3bs and the OSFP MSA.

The 400G-OSFP-500 is made to order and carries EDGE Optical Solutions' standard 5-year warranty against defects in materials and workmanship. For project quantity pricing or platform verification, contact our sales team.
