The eSFP-GE-SX-MM850 optical module is a Huawei Gigabit multimode optical module with DOM/DDM support, which is packaged in an SFP package with a center wavelength of 850 nm. An eSFP module is an SFP module that supports monitoring of voltage, temperature, bias current, transmit optical power, and receive optical power. Therefore, eSFP is also called SFP sometimes. When used with multimode optical fiber (LC/PC-LC/PC OM2), the transmission distance can reach up to 550 m, the transmission. Applicable cable and maximum transmission distance · Multimode fiber (with modal bandwidth of 160 MHz*km and diameter of 62. 22 km · Multimode fiber (OM1): 0. Every eSFP-GE-SX-MM850 is environmentally tested in its specific port/platform prior to shipping to ensure that they are in perfect physical and.
