Modul Cisco GLC-ZX-SM SFP

Descriere

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, interfață, and commercial temperature of the three optical modules are the same, but the other aspects are different. De exemplu, 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、Comparație GLC-ZX-SM

Aceste trei module optice nu sunt absolut bune sau rele, trebuie să alegeți modulul optic potrivit în funcție de aplicația dvs. de rețea. Din punct de vedere funcțional. Vedea, Cisco GLC-LH-SMD, Modulele optice GLC-SX-MMD au mai multe funcții DOM decât modulele optice GLC-ZX-SM, dacă trebuie să aveți funcția DOM Pentru module optice, nu se recomanda alegerea modulului optic GLC-ZX-SM. Dacă aveți nevoie de un modul optic la distanță lungă, este recomandat sa alegeti un modul optic GLC-ZX-SM cu o distanta de transmisie de 70km; dacă este o transmisie pe distanțe scurte, puteți

Selectați modulul optic GLC-SX-MMD cu o distanță de transmisie de 550 m; dacă aveți nevoie de transmisie de date de 10 km, se recomandă să selectați modulul optic GLC-LH-SMD.
