What is the new SFP module range?

This is a series of optical transceivers compatible with SFP and SFP+ ports that offer varying operational distances depending on the type of fiber used. The range includes multimode modules for short distances and single-mode modules for long-distance links, including bidirectional (BiDi) models on a single strand.

What are the main features?

The new modules are distinguished by precise technical specifications:

  • HS-85DLC05D: Supports 1G/2.5G on multimode fiber up to 550 m, wavelength 850 nm, LC connector. Price: $22.
  • HS-31DLC20D: Supports 1G/2.5G on single-mode fiber up to 20 km, wavelength 1310 nm, LC connector. Price: $29.
  • HS-2733LC20D: Pair of SFP 1G/2.5G single-mode modules for bidirectional links up to 20 km on a single strand. Price: $79.
  • S+2733LC10D: Pair of SFP+ 10G single-mode modules for bidirectional links up to 10 km on a single strand. Price: $139.

Who is it for and where does it make sense to use it?

These modules are designed for network administrators and WISPs who need to expand industrial fiber optic connectivity. They are suitable for backbones, campus infrastructure, and ISP networks where a specific combination of speed (1G, 2.5G, or 10G) and distance is required. Bidirectional models are particularly useful when only a single optical strand is available for the link.

What to know before choosing it?

It is essential to verify the compatibility of the fiber type (multimode or single-mode) with the existing infrastructure and the maximum distance supported by the chosen module. The HS-2733LC20D and S+2733LC10D modules are sold as a pair, as they require two matched transceivers to operate on a single strand. The prices indicated are in US dollars and represent the official MikroTik list price.

Frequently asked questions

What is the maximum distance of the HS-85DLC05D module?

The HS-85DLC05D module supports links on multimode fiber up to 550 meters with a wavelength of 850 nm.

Which modules support 10G speeds?

Only the S+2733LC10D model supports 10G speeds, operating as a pair of SFP+ modules on single-mode fiber up to 10 km.

How does bidirectional technology work in the new modules?

The HS-2733LC20D and S+2733LC10D models use bidirectional technology to transmit data in both directions on a single optical fiber strand, reducing the number of cables required.

What is the price of the HS-31DLC20D single-mode SFP module?

The HS-31DLC20D 1G/2.5G single-mode SFP module, which covers distances up to 20 km, has a list price of $29.
