Optics and Optical Networking

Hello,I have an question about the SFP-10G transceiver. For example, I have two Cisco switches, one has an SFP-10G-SR and the other one has an SFP-10G-SR-S transceiver. Would this work in a productive environment?

Hello,we have switched network (SG300 cisco) connected using fiber optic(SFP), how can we detect any abnormal external behavior (such as tapping, physical attack, cutting, detecting connected optical splitter...) in order to protect our optical commu...

Hi, A customer is using a pair of 3560-x with C3KX-NM-10G modules. The connection between the two switches are Multimode OM1 and approx 140 meters. 10Gb is running with no problems. SFPs is SFP-10G-LRM. Now the customer is trying to replace the 3560-...

Hi, I have a Cisco 9200L Switch and would like an indication of which single-mode SFP model I should use? Is it possible to enable third-party modules on this equipment? I found some articles with command to release the third party module but did not...

Can we use SFP-10G-T-X on 10G network module of catalyst 9200

Using two C3850 48 port, stacked network switches each with a C3850-NM-4-1g module.  Adding SFP modules for fiber single-mode LC connectors.  Ports are configured the same and not shut down, active.  None of switch 1 shows activity using the SFP modu...

We are upgrading out internet connection to 10 gbps.   Which uplink transceiver will we need for a fiber connection?

Hi AllI have a 3064 and a 9372tx interconnected with a compatible QSFP DAC cable.Problem is the interfaces won't come up. Status not connected.The 3064 hardware profile was initially set to 64x10G but I changed that to 48x10g+4x40g.I have forced both...

I need clarification on using the CVR-QSFP-SFP10G 1) I believe on 9372X the speed group ports are 49-54 2) because the CVR-QSFP-SFP10G converts the 40G port to 10G is the speed-group command 10000 or 40000? 3) does the speed-group command only need t...

Hi, We cannot see the transceiver detail as below. ================ Hardwarecisco Nexus9000 C9372TX chassis SoftwareBIOS: version 07.17NXOS: version 7.0(3)I1(2)BIOS compile time: 09/10/2014NXOS image file is: bootflash:///n9000-dk9.7.0.3.I1.2.binNXOS...

So, a while back our fiber vendor who we lease from was doing some work (unknown what) between Point A and Point B. Ever since we keep losing our neighborship with the next IE switch in the daisy-chain. They've had me change out the optics, but I sti...

Hi all,One of our new project requirement is to transmit 100MHz clock over optical fiber, 1550nm, single mode fiber. transmitter board have 100MHz pure clean clock source with phase noise -130dBc/Hz at 100Hz offset, this clock need to transmit using ...
