Detailed H3C SFP-GE-SX-MM850-A/D optical module model

  • December 11. 2021

The SFP-GE-SX-MM850 optical module is a gigabit multimode optical module with a transmission rate of 1.25G. Its package type is hot-swappable SFP with a center wavelength of 850nm. It is used with multimode OM2(LC/PC-LC/PC) patch cord when the transmission distance up to 550m, can also be used with multi-mode OM1(LC/PC-LC/PC) patch cord up to the  transmission distance of 275m.

 

 

The comparison of the parameters of SFP-GE-SX-MM850-A and SFP-GE-SX-MM850-D is as follows:

SFP-GE-SX-MM850-A and SFP-GE-SX-MM850-D optical modules have the same parameter specifications, and the only difference between them is the connotation of their last letter, specifically, model SFP-GE-SX-MM850 -A, the letter A refers to industry users (such as schools, enterprises), while the model SFP-GE-SX-MM850-D, and the letter D stands for operators' exclusive use (such as China Telecom, China Unicom).

 

Next, ETU-LINK will take you to interpret the meaning of the SFP-GE-SX-MM850 model, where "SFP" refers to the packaging type of the optical module; "GE" refers to the transmission rate of the optical module is 1G; “SX” refers to the transmission distance of the optical module is 550m; 850 indicates that the central wavelength of the optical module is 850nm. Besides, “MM” refers to the optical fiber type of the optical module as multimode. Generally speaking, Multimode optical fibers can be classified into OM1, OM2, OM3, and OM4. Usually, gigabit multimode optical modules are equipped with OM2 optical fiber patch cords.

 

H3C SFP-GE-SX-MM850 optical module and ETU-LINK ES8512-3LCD05 optical module have the same parameters and can be used in H3C equipment. ETU-LINK ES8512-3LCD05 Gigabit multimode optical module is relatively more cost-effective, has more advantages in price and warranty time, and can support compatibility with various brand equipment. Both optical modules conform to the SFP MSA standard, IEEE 802.3z standard, and ROHS standard, and both support the digital diagnostic monitoring that conforms to the SFF-8472 protocol.

 

ETU-LINK is an optical module manufacturer that has obtained the national high-tech enterprise certificate. It is continuously providing complete and effective optical network deployment solutions, high-quality optical communication products, professional technical guarantees and a complete service system for the majority of industry users.
