IE-3000-Transceiver Issue

[eamon.byrne]

Hi All,

I'm receiving this error message when trying to connect a cisco IE-3000-4TC switch IOS 15.2(3)EA to a cisco WS-C3850-48T-E stack switch ver 16.3.3 using GBIC's GLC-BX40-UI. I'm using SMF LC-to-LC.

I've tried to manipulate the fibre but the value's still stay the same.

%PHY-5-TRANSCEIVERINSERTED: Slot=1 Port=1: Transceiver has been inserted
.May 22 10:14:09: %SFF8472-5-THRESHOLD_VIOLATION: Gi1/1: Rx power low alarm; Operating value: -40.0 dBm, Threshold value: -28.8 dBm.

Any help greatly appreciated.

Thanks.

Hello,

these are special types of SFP that work on a single fiber, however two different types of SFP are needed to build a working link

Wavelength: What type of SFP is on the other side? You need the companion SFP that transmits on 1550 nm and receives on 1310 nm wavelenghths Hope to help Giuseppe Edit: see The 1000BASE-BX-D and 1000BASE-BX-U SFPs, compatible with the IEEE 802.3ah 1000BASE-BX10-D and 1000BASE-BX10-U standards, operate on a single strand of standard SMF. on https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/gigabit-ethernet-gbic-sfp-modules/product_data_sheet0900aecd8033f885.html
