Cisco GLC-SX-MMD SFP Module is 1000BASE-SX SFP transceiver module, MMF, 850nm, DOM -option This part is also known as CSC-GLCSXMMD.
Cisco GLC-SX-MMD SFP Module Product Overview
this SFP s designed for use with Cisco networking equipment and is functionally equivalent to Cisco part number GLC-SX-MMD=. This transceiver is manufactured to meet or exceed the specifications of the original Cisco unit and to comply with the Multi-Source Agreement (MSA) standards. Tripp Lite guarantees 100% compatibility with Cisco networking hardware and will initialize and perform identically to an OEM transceiver.
The information about the optical modules contained in the labels of the Cisco optical modules can help us distinguish optical modules. Sebagai contoh, SX and SR in optical module models represent short distances. Penularan, ZX, EXZ stands for long-distance transmission, dan lain-lain. Namun begitu, due to the variety and type of Cisco optical modules, we still easily confuse different types of optical modules. In this article, we will focus on the differences between Cisco GLC-LH-SMD, GLC-SX-MMD, dan modul optik GLC-ZX-SM. Divided into several types of optical modules.

Lihat jenis pakej, kelajuan, antara muka, dan suhu komersial bagi tiga modul optik adalah sama, tetapi aspek lain berbeza. Sebagai contoh, kita boleh lihat dari model. In addition to the “D” in the model of the GLC-ZX-SM optical module, dua lagi modul optik tersedia, and the “D” at the end of the model represents DOM work.Daripada GLC-LH-SMD, GLC-SX-MMD, dan modul optik GLC-ZX-SM. Kita boleh
ya, this means that the GLC-ZX-SM optical module does not support DOM functionality, manakala dua lagi modul optik menyokongnya.
GLC-LH-SMD、GLC-SX-MMD、Perbandingan GLC-ZX-SM
Ketiga-tiga modul optik ini tidak benar-benar baik atau buruk, anda perlu memilih modul optik yang betul mengikut aplikasi rangkaian anda. Dari sudut fungsi. Lihat, Cisco GLC-LH-SMD, Modul optik GLC-SX-MMD mempunyai lebih banyak fungsi DOM daripada modul optik GLC-ZX-SM, jika anda perlu mempunyai fungsi DOM Untuk modul optik, tidak disyorkan untuk memilih modul optik GLC-ZX-SM. Jika anda memerlukan modul optik jarak jauh, adalah disyorkan agar anda memilih modul optik GLC-ZX-SM dengan jarak penghantaran 70km; jika ia adalah penghantaran jarak dekat, awak boleh
Pilih modul optik GLC-SX-MMD dengan jarak penghantaran 550m; jika anda memerlukan penghantaran data 10km, adalah disyorkan agar anda memilih modul optik GLC-LH-SMD.
