#1000base-lx

Обычно мы видим LX SFP, LH SFP и LX/LH SFP на многих веб-сайтах, и многие люди показывают свое замешательство в них. Являются ли они одинаковыми или разными? Если они отличаются друг от друга, какие различия между ними на земле?

Часто Используемые Стандарты 1000BASE-X по Ethernet

Ethernet был результатом исследований, проведенных в Xerox PARC в начале 1970-х годов. Ethernet позже превратился в широко реализованный протокол физического и канального уровня. Fast Ethernet увеличил скорость от 10 до 100 мегабит в секунду (Мбит/с). Гигабитный Ethernet стал следующей итерацией, увеличивающей скорость до 1000 Мбит/с. Первоначальный стандарт для Gigabit Ethernet произвелся в июне 1998 года в качестве IEEE 802.3z, и требовал оптического волокна. 802.3z обычно называют 1000BASE-X, который используется в промышленности для обозначения передачи Gigabit Ethernet по оптоволокну, где варианты включают в себя 1000BASE-SX, 1000BASE-LX, 1000BASE-LX10, 1000BASE-BX10 или нестандартный -EX и -ZX.

Спецификации Оптического Интерфейса Gigabit Ethernet 1000BASE-LX

1000BASE-LX - это волоконно-оптический стандарт Gigabit Ethernet, указанный в разделе IEEE 802.3, который использует длинноволновый лазер (1,270-1,355 нм). 1000BASE-LX SFP предназначен для работы на расстоянии макс.до 10 км по одномодовому волокну и может также работать по всем распространенным типам многомодового волокна с максимальной длиной сегмента 550 м. Для расстояний линии связи состоит более 300 м, вы должны установить патч-корд для настройки режима между модулем и кабелем MMF на обоих концах линии связи.

Спецификации Оптического Интерфейса 1000BASE-LH и 1000BASE-LX/LH

LH значит Long Haul. Многие поставщики используют LH и LX/LH для определенных модулей SFP, но они вообще не являются стандартом Gigabit Ethernet. 1000BASE-LX/LH SFP может достигать расстояния макс.до 20 км по одномодовому волокну. В отличие от 1000BASE-LX/LH SFP, 1000BASE-LH SFP работает на расстояние макс.до 70 км по одномодовому волокну.

Вывод

Recently, Ubiquiti Network Switch is of prevalence for building and expanding home network. EdgeSwitch and Unifi Switch are two main switch series of the Ubiquiti Network Switch. For years, the EdgeSwitch and Unifi Switch are featured as cost-effective, robust performance, and this is why many people have special favour on them. For they both a good choice for growing networks, it is necessary to make clear their differences and decide which one to choose. In this article, we will mainly introduce the EdgeSwitch and Unifi Switch, similarities and differences as well as compatible SFP transceivers for them.

Introduction to Unifi Switch

The Unifi Switches provide 8, 16, 24, or 48 PoE Gigabit Ethernet ports to satisfy different requirement for expanding Gigabit Ethernet network and making your network cabling looks neat. They support IEEE 802.3af and IEEE 802.3at. And the operation is rather easy, you can directly connect your switch to a storage server through two SFP ports on each switch. The transmission rate can be up to 1 Gbps. For longer distance and higher bandwidth, you can use Unifi Switch with 48-port which additional added two more SFP+ port. The following picture shows a basic parameter of all the Unifi Switches models.

Information About EdgeSwitch

As same as Unifi Switch, the EdgeSwitch have the same PoE Gigabit Ethernet ports and IEEE protocols. The most distinctive feature of Edgeswitch is that offers an extensive suite of advanced Layer-2 switching features and protocols, and also provides Layer-3 routing capability. There are 6 EdgeSwitch models, the accurate ports’ number are clearly shown in the below chart. You can use ES-8-150W, ES-16-150W and ES-24-250W as well as ES-24-500W switch models to achieve 1G Ethernet network connectivity. For SFP+ transceivers, you can choose ES-48-500W, ES-48-750W to arrive 10 Gbps connection.

Similarities

Both Unifi Switch and EdgeSwitch have 8, 16, 24, or 48 PoE Gigabit Ethernet ports.

—Switch models

The two switch basically share the identical switch type (switch ports and Watts), the only difference lies in the EdgeSwitch does not have one with 8 ports for 60W.

—Protocols

The Unifi Switch and EdgeSwitch both support IEEE 802.3af and IEEE 802.3at.

—Supporting Gigabit Ethernet

They are both support 1G and 10G Ethernet connection and have both SFP and SFP+ ports.

Differences

—Color

The EdgeSwitch is black while the Unifi Switch is silver.

—Management

The Unifi Switch can only be managed through the UniFi controller while the EdgeSwitch can only be managed through it's CLI or web interface.

—Routing protocols

The EdgeSwitches only support static routing, and there are no routing protocols implemented while Unifi Switches don't support routing at all.
