Modul Cisco GLC-ZX-SM SFP

Popis

Cisco GLC-ZX-SM SFP Module is 1000BASE-ZX SFP. This is a Duplex SFP transceiver for optical communications, rated for distances up to 70 km and a maximum bandwidth of 1Gbps. The GLC-ZX-SM transceiver operates at 1550nm wavelength. The 1000BASE-ZX SFP operates on standard single-mode fiber-optic link spans of up to approximately 70 km in length. The SFP provides an optical link budget of 23 dB, but the precise link span length depends on multiple factors such as fiber quality, number of splices, and connectors.

Cisco GLC-ZX-SM SFP Module Product Overview

It operates on standard single-mode fiber-optic link spans of up to approximately 70 km in length. The SFP provides an optical link budget of 21 dB, but the precise link span length depends on multiple factors such as fiber quality, number of splices, and connectors. When shorter distances of single-mode fiber (SMF) are used, it might be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. A 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the SFP at each end of the link whenever the fiber-optic cable span loss is less than 8 dB.

From GLC-LH-SMD, GLC-SX-MMD, and GLC-ZX-SM optical modules. We can

See the package type, speed, interface, and commercial temperature of the three optical modules are the same, but the other aspects are different. Napríklad, we can see from the model. In addition to the “D” in the model of the GLC-ZX-SM optical module, the other two optical modules are available, and the “D” at the end of the model represents DOM work. This means that the GLC-ZX-SM optical module does not support DOM functionality, while the other two optical modules support it.

GLC-LH-SMD、GLC-SX-MMD、GLC-ZX-SM Comparison

These three optical modules are not absolutely good or bad, you need to choose the right optical module according to your network application. From a functional point of view. Pozri, Cisco GLC-LH-SMD, GLC-SX-MMD optical modules have more DOM functions than GLC-ZX-SM optical modules, if you need to have DOM function For optical modules, it is not recommended to choose the GLC-ZX-SM optical module. If you need a long-distance optical module, it is recommended that you choose a GLC-ZX-SM optical module with a transmission distance of 70km; if it is a short-distance transmission, you can

Select the GLC-SX-MMD optical module with a transmission distance of 550m; if you need 10km data transmission, it is recommended that you select the GLC-LH-SMD optical module.
