single strand fiber cable

[knaik99]

1. is it necessary to use this type of cable with media conveter or we can use SFP ?

2.if yes, Can we use SFP for this fiber in 3850 model?

Sorry, by single strand fiber cable do you mean Single Mode Optical Fiber (SMOF)?

If so you are able to directly connect it to your Cisco 3850 Switch without needing a media convertor using a SFP module however:

1. What is the connector type on the cable (LC, SC, MTRJ, etc)?

2. What speed is the cable going to be used (100mb, 1G, 10G, 40G)?

3. What model is the Network Moduel (NM) in your 3850 Switch (4-1G, 2-10G, 4-10G, etc)?

By gathering this info, its possible to determine what you will require.

Short answer though, yes, you can use SMOF directly to a 3850 using a SFP module.

To connect to a 3850 switch, you need 2 strands (one pair) of fiber cable. One strand is used for transmit and one strand is used for receive.

Hi,

Single strand fibre or as we call it here in the UK single fibre working.

For the 3850 - Yes it is supported

Here are a couple of links for you to explore.

This is about many SFPs/Transceivers , the Single strand ones are in the "BX" range

https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/gigabit-ethernet-gbic-sfp-modules/datasheet-c78-366584.html

 You are then pointed at the SFP matrix and you will eventually land on the new Transceiver  module group tool TMG

Put in some details about your switch like 3850, pick length of fibre, type of cable etc you then see what SFPs meet your requirements

Hope this helps

as per that site update,

I have to use two SFP i.e. GLC-BX-D & GLC-BX-U 

my A end is ws-c3850-12s-s & B end is ws-c2960x-48fps-l so I have 2 queries--

1. Can 2960x support single strand SFP?

2.do I have to use GLC-BX-D at A end and GLC-BX-U at Z end or vice versa?

Hi,

Same TMG tool -- searched for 2960x-48fps

https://tmgmatrix.cisco.com/?npid=654

Yes the GLC-BX-D is supported.

Hi,

You are correct you need a GLC-BX-D at one end and a GLC-BX-U at the other.

GLC-BX-D -------> 1490nm ------> GLC-BX-U
GLC-BX-D <------- 1310nm <------ GLC-BX-U

So the light paths are split by a different wavelength in each direction allowing full duplex working on a single strand fibre.

Clever stuff :)
