![]() Primary parameters of the optical modules 1. Transmission rate The transmission rate alludes to the quantity of bits transmitted every second in units of Mb/s or Gb/s. Primary rates: 100M, Gigabit, 2.5G, 4.25G and 10G, 25G, 40G, 56G, 100G, 120G, and so forth. In this way, in view of various information rate, our optical handset modules organize 100M, 1G/2G/4G SFP module, 10G SFP+/XFP, 16G SFP+, 25G SFP28, 40G QSFP+, 56G QSFP+, 100G CFP/CFP2/CFP4/QSFP28 Module. 2. Transmission separation The transmission separation of the optical module is partitioned into short separation, medium separation and long separation. It is commonly viewed as that a short separation is 2 km or less, a medium separation of 10 to 20 km, and a long separation of 30 km, 40 km or more. ■ The transmission separation of the optical module is constrained, essentially in light of the fact that the optical sign has a specific misfortune and scattering when transmitted in the optical fiber. note: • Loss is the loss of light vitality because of assimilation and dissipating of the medium and spillage of light as it goes through the fiber. This vitality is scattered at a specific rate as the transmission separation increments. • Dispersion is principally brought about by the inconsistent speed of electromagnetic influxes of various wavelengths spreading in a similar medium, which causes diverse wavelength parts of the optical sign to arrive at the less than desirable end at various occasions because of the gathering of transmission separation, bringing about heartbeat widening and in this way failure to recognize Signal worth. • Therefore, clients need to choose the suitable optical module as indicated by their real systems administration conditions to meet diverse transmission separation prerequisites. 3. Focus wavelength • The inside wavelength alludes to the optical band utilized for optical sign transmission. Right now, there are three principle sorts of optical wavelengths ordinarily utilized in optical modules: the 850 nm band, the 1310 nm band, and the 1550 nm band. • 850nm band: generally utilized for short separation transmission of ≤2km • 1310nm and 1550nm groups: generally utilized for medium and long separation transmission, more than 2km transmission. Likewise, clients additionally need to affirm which brand of their gear, which will choose the compatibility of the SFP handset modules. Please Follow Us in Facebook and Twitter
