About this product

Please note: this is a non-returnable item (excluding faulty goods)

Comnet CNMC2SFP is a media converter from the CNMC[2]SFP[POE][/M] range.

The Comnet CNMCSFP electrical-to-optical Ethernet media converters accept a 10/100 or 1000 Mbps electrical input and converts this to a 100 or 1000 Mbps optical output (selected by a dip switch) and the 100/1000 Mbps optical input back to the 10/100/1000 Mbps electrical output. “Auto-Negotiating” is supported on the copper interface side. These devices use either one or two optical fibers, depending upon the selection of sold-separately SFP† optical module.

A PoE model, the CNMCSFPPOE/M meets the IEE802.3at standard and provides 30 watts of PoE+ power. The series consists of a small-size single channel model, CNMCSFP/M; a ComFit standard size, single-channel model, CNMCSFP; a dual channel model, CNMC2SFP; and a quad channel model, the CNMC4SFP.

Key features

  • Full-duplex transmission of 10/100/1000 Mbps Ethernet - 10/100/1000BASE-TX electrical port - 1000BASE-FX or 100BASE-FX optical port when used with suitable Comnet SFPs
  • IEEE 802.3 compliant
  • 10/100/1000 BASE-TX port supports auto-negotiation and automatic MDI/MDI-X crossover for full and half-duplex operation
  • Uses customer-installed Comnet SFPs for compatibility with a wide range of optical fibers, optical connector types, and optical transmission distances of up to 120 km
  • Designed for installation in harsh out-of-plant/unconditioned industrial or roadside operating environments (-40º to +75ºC ambient). Fully compliant with the environmental requirements of NEMA TS-2 for Traffic Signal Control Equipment
  • Voltage transient protection on all power and signal input/output line provide protection from voltage surges and other transient events
  • Mini-package size of the CNMCSFP/M allows the unit to be installed in those locations where space is at a premium.
  • Supports Jumbo Frames up to 10K Bytes for streaming video applications
  • Bi-color LED status indicators confirm operating status
  • Hot-swappable rack modules

If you are matching this to an existing installation, work from the CNMC2SFP part number rather than the description.

Who this is for

For the installer — this is the media converter supplied under Comnet part number CNMC2SFP. Specify it by that part number.

The entries in the specification table are the ones held against this part number. Anything not listed there is not stated by us, and should be confirmed against the manufacturer's own documentation.

In plain English: this is a media converter made by Comnet. The part number CNMC2SFP is the manufacturer's own code for this exact version of it.

Similar-looking items in the same family often differ only by a suffix on that code. If you are replacing something, match the code rather than the picture.

Buying this in the UK

We are a UK supplier and this media converter is sold and shipped from the UK. Prices are shown in pounds sterling.

This item is non-returnable, excluding faulty goods. That restriction comes from the manufacturer's own terms for this line.

We do not quote a warranty term for this part. Every supplier-stated term we have checked against the manufacturer's own document has turned out to be wrong, so we would rather say nothing than say something we cannot stand behind.

Ask us and we will check it for you. Your statutory rights are unaffected.

Stock on this line moves, and lead times move with it. Ask us for the current position before you commit to a date on site.

Questions we get asked

Is this the exact media converter I have been quoted? Check the manufacturer part number CNMC2SFP against your quote. That code is the only reliable identity for this item.

Is there a datasheet? Yes — the documentation attached to this listing was checked and names this exact part number. Documents that named only the family, or a different item, are not attached.

Can you check compatibility for us? Ask before you order and we will check it against the manufacturer's own documentation. We do not state compatibility that the record does not carry.

Why does the listing not answer every question? Because the specification held against CNMC2SFP answers some questions and not others. We would rather leave a gap visible than fill it with something we cannot show you.

What if I order the wrong version? Tell us the installation you are matching and we will work back to the part number with you. That is a faster conversation than a return.

Do you hold this in stock? Availability on this line changes through the week, so the honest answer is to ask us on the day. We will give you the current position rather than a general one.
