Compatible SFP Module and Patch Cable for MikroTik CRS328-4C-20S-4S+RM Switch

Unlike expensive network switch brands like Cisco and HPE, MikroTik is committed to providing products with highly competitive pricing and top price/performance. On this side, OPTCORE is also similar to MikroTik. Our greatest goal is to provide our customers with optical modules and optical link solutions with excellent price/performance ratios.

In this post, we focus on the MikroTik CRS328-4C-20S-4S+RM switch, a middle-end enterprise switch. This post will provide an overview and introduce our compatible SFP and LC fiber patch cable.

MikroTik CRS328-4C-20S-4S+RM Switch Overview

As a middle-end ethernet switch for high-speed and density business networks, the CRS328-4C-20S-4S+RM provides 28 independent ports. As described in the model number, the “28” in CRS328 means a total of 28 ports, the 4C means 4 combo ports, and the rest of the models mean 20x SFP (the 20S) or 4x SFP+(4S+) rackmount form factor type(RM).

The SFP port supports various 1G SFP modules, such as dual fiber, BiDi, CWDM, and DWDM. At the same time, the SFP+ port supports a broad line of SFP+ modules for uplink connectivity. The four RJ45 ports and the four SFP ports adjacent to them on the left form a combo port group. The OS software easily allows the user to select which four combo ports will be active.

Unlike the low-end switch models, the CRS328-4C-20S-4S+RM switch is equipped with dual PSUs, providing a redundant power supply to prevent downtime losses. Besides that, this switch also offers rich enterprise features, such as IEEE 802.1Q VLAN, STP / RSTP / MSTP, Port isolation, and Port mirroring.

Is CRS328-4C-20S-4S+RM Worth Buying?

The list price on the Mikrotik official website is 449$. However, you can even get a 15% discount in some distributor stores, as low as 385$. This price is affordable and competitive for enterprises and small operators.

Let’s compare similar models on the market, like the Ubiquiti Pro Max 24 and TP-Link TL-SG3428XF. The CRS328-4C-20S-4S+RM provides more features and fiber ports than the Pro Max24 while still having very similar pricing. It has similar fiber ports and switching capacity as the TP-Link TL-SG3428XF, but the price is only 75% of it.

So, overall, the CRS328-4C-20S-4S+RM switch is ideal for small and medium-sized business networks, small carriers, and data centers with fiber connectivity. Especially for users with limited cost budgets and requiring high throughput networks, he is priced much lower than the same class of Cisco and HPE products, which can help you build and maintain a cost-effective fiber-optic connectivity network.
