Frequently Asked Questions
What Are My Options For ComNet Product Mounting?
A standard-size ComNet device (“ComFit” device) may be mounted to a surface as a standalone device or may be inserted into a ComNet 19-inch rack-mountable card cage without modification. If the use of a card cage is being considered but initial quantities do not justify the use or expense of a card cage, this feature could allow the purchase of the card cage to be delayed until future expansion makes the use of a card cage more practical. At that time, the ComNet units may be unmounted and simply inserted into the card cage without modification.
The C1-US is a 19-in rack-mountable card cage with fourteen slots and it includes an integral power supply. The C2-US is the same except it is designed to accommodate two integral power supplies for redundancy.
Do You Offer Conformal Coating Protecting ComNet Products in Extremely Hard Environments?
There’s an additional step you can take to protect your ComNet products in environments where humid salt air and chemicals may be affecting the long-term performance of your ComNet Products. The suffix /C indicates that the circuit board in the device has been sprayed with a protective conformal coating. A customer will request conformal coating when it is anticipated that the device will be deployed in a location with high humidity, a location near saltwater, in a chemical plant, or in any location where the circuit board needs additional protection from condensing humidity or other adverse environmental conditions.
What Is The Difference Between CLRFE1EoCE/m & CLRFE1EoCP/m vs CLFE1EoC?
CLRFE1EoCE/m and CLRFE1EoCP/m are small Ethernet extender units for the remote side of extended Ethernet links. The CLRFE1EoCE/m is not capable of passing PoE through the extended link and must be powered by low voltage. The CLRFE1EoCP/m is designed for pass through PoE applications only – it must receive its operating power from the pass through PoE and there is no option for traditional low voltage power.
A slightly larger device – the CLFE1EoC – may be considered instead. It has the ability to pass PoE through the extended link but it can be powered with low voltage, if pass through PoE will not be used.
50/125 vs 62.5/125 Multimode Fiber: How To Decide?
Commonly available multimode fiber core diameters are 50 µm and 62.5 µm (µm pronounced “micro meter”). In both cases, the cladding diameter remains 125 µm. The same fiber modem will also work with both types of multimode fiber. Performance quality will remain the same however the maximum operating range may change. In some cases, range may increase with the use of 50 µm fiber while in other cases, it may decrease.
For applications that are inherently low bandwidth or low data rates such as single-channel serial data or single-channel analog video using analog fiber modems, optical power budget will typically be the limiting factor concerning maximum range. Applications that involve high bandwidth, high data rates, or digital fiber modems will usually be limited in range by the multimode fiber bandwidth – specifically limited by a phenomenon called modal dispersion introduced by the multimode fiber itself.
Gigabit via Multimode Fiber
When multimode fiber is used to pass 1000BASE-SX (the optical Gigabit Ethernet standard that uses the 850 nm wavelength), fiber path lengths are limited. ComNet items SFP-SX and SFP-16 both comply with the 1000BASE-SX standard. The following are recommended maximum path lengths when using ComNet SFP-SX or SFP-16 on multimode fiber:1. 62.5/125 (FDDI Grade): 220 meters (about 700 feet)
2. 62.5/125 (OM-1): 275 meters (about 900 feet)
3. 50/125 (OM-2 or better): 550 meters (about 1,800 feet)
