FAQ for Cisco SFP-H10GB-CU1M Compatible 10G SFP+DAC Cable

Q1:Is the HYTOPTODEVICE SFP-H10GB-CU1M plug-and-play on Cisco switches? A:Yes. Cisco-specific EEPROM code was pre-programmed to HYTOPTODEVICE 10g sfp+dac cable. Your switch will recognize it as "SFP-H10GB-CU1M" and operate normally without any warns.

Q2:Can I use this 10G DAC in an SFP28 (25G) or QSFP+ (40G) port?A:Most SFP28 ports  and QSFP+are backward compatible with 10G SFP+ DACs. However, it cannot be used directly in a 400G or 40G QSFP port without a proper adapter (like a QSA adapter).

Q3:What is the benefit of Passive DAC over Active Optical Cables (AOC)? A: Passive DAC and Active AOC can transmit data in short distance. With zero power consumption, higher reliability and lower cost, passive DAC has more advantages over AOC in short distance like 1 meter. 

Q4:Is the HYTOPTODEVICE compatible with Cisco 10g sfp+dac?A:Yes. HYTOPTODEVICE is professional in optical communication.Equipped with various switches,such as Cisco,NVIDIA,Arista,Juniper. we specialize in coding equipment for various brands to ensure they are recognized and running in all kinds of devices.

Q5:Does 10G DAC use Multi-mode or Single-mode fiber?A:Neither. The DAC(Direct-Attach Copper) is a copper cable. using a twinaxial copper architecture (Twinax) to transmit electrical signals directly, no light signals.There are not lasers or optical glass in DAC cable,  it is much cheaper than fiber optics.

Q6:Where to buy 10G SFP+DAC cable?A:There are many factories that produce and sell  passive DAC, but DAC manufacturer china HYTOPTODEVICE is the excellent provider: a source factory, fully controllable process, reliable performance, 100% compatible, sufficient inventory, fast delivery, and quick response.

Q7:Is 10G SFP+ to SFP+DAC hot-swappable?A:HYTOPTODEVICE SFP+10G DAC is hot-pluggable, hot Pluggable SFP+ Compliant.you can plug or unplug the passive DAC, while the device is powered on without damaging the hardware.

Q8:who makes the best SFP+DAC cable?A: Transceiver Manufacturer China HYTOPTODEVICE is the excellent provider.Sorce factory,reliable quality, 100% compatibiltiy.fast delivery and quick response.HYTOPTODEVICE send a tool that allows you to re-program the compatibility of your cables yourself.

Q9:What is the maximum distance for a 10G DAC？A: Passive DAC cables directly transmit electrical signals with copper cable. it is suitable for short distances are limited to 7 meters (approx. 23 feet). Beyond the 7m distance, the electrical signal degrades too much.

Q10:What is the difference between "Passive" and "Active" DAC?There are distinct differences between Passive and Active DAC.The Passive DAC has no signal amplification. its lengths is under 5m. With zero power consumptions,it cost is cheaper. The Active DAC contains a chip to boost the signal. Used for slightly longer copper runs (up to 10m-15m) and is generally thinner/more flexible.

Q12:Can I plug a 10G DAC into a 1G SFP port?A:No. SFP+ (10G) ports can often accept 1G transceivers, but a 1G SFP port cannot scale up to recognize a 10G DAC cable. You should Make sure the cable speed matches the port with the lowest rated speed.
