Gigabit switch electrical module optical interface is also called 10G SFP + electrical interface module, which is designed for high speed communication link is designed with respect to the normal of the optical module, the optical Gigabit switch power module is electrically ordinary light module one-half, and stable performance can be achieved through the 10G transmission network cable, it is widely used in Gigabit Ethernet. Next is easy to communicate to you on the sky 10G SFP + electrical module!
10G SFP + optical module electrical interface description:
10G SFP + RJ45 interface provided, integrated in the main switch, network cards and other products, the use of full-duplex transmission band echo suppression, PAM16 pulse amplitude modulation technique, standard operating bandwidth requirements 417MHz.
Mainly used in the super-six (CAT6A) or seven categories (CAT7) copper cabling system 10G Ethernet transmission is completed, it is consistent with SFF-8431 and SFF-8432 MSA standard, to achieve the maximum transmission distance of 30m. Further, as compared with the high-speed cable SFP +, 10GBASE-T SFP + module electrical interface optical power can be saved at least 0.5W, and its RJ-45 interface is capable of supporting both unshielded twisted pair, unshielded twisted pair can support.
High-speed cable SFP + VS 10G SFP + module electrical interface optical SFP + VS optical module:
1. Now the distance between the inner most link data center equipment between 10m to 100m, using 10G SFP + Gigabit electrical module can make up for deficiencies SFP + high-speed cable transmission distance.
2.10G SFP + module electrical interface uses optical RJ45 interface, and super-six or seven categories for use with cable, and copper cabling costs lower than the fiber optic cabling.
3.10 g of light SFP + module electrical interface can be implemented directly in existing copper transmission 10G wiring system, using optical SFP + module wiring cable is required, which increases the cost of deployment. If you want to use optical SFP + module into existing copper cabling system, the Ethernet switch or the like need to increase the photoelectric conversion device.
Considerations when choosing 10G electrical interface modules:
1. How selected rate or a single rate. 10G rate electrical interface module that supports multi-rate (1-10Gb / s), but also only support a single rate (10Gb / s) is.
2. The different operating temperature range. Electrical interface module 10G commercial grade and industrial grade, commercial operating temperature range of 0-70 deg.] C, industrial operating temperature range of -45-80 ℃.
3. Main different chips.
10G SFP + optical module electrical interface scenarios:
RJ45 and SFP + module interface is not directly interconnected, a need to SFP + modules RJ45 interface converter, 10G electrical module is such a converter. 10G through the electrical interface module and Cat6 cable, can make electrical port Gigabit RJ-45 interface card, and SFP + Gigabit switch interconnect interface.
Use: first electrical port 10G SFP + module into optical Gigabit switch interface, and direct RJ45 cable interface card and can be successfully connected Gigabit Gigabit switch.
