EX4600 does not create an interface for a third-party 1G WDM SFP coded as Fibre Channel

On a Juniper EX4600 running Junos 14.1X53-D27.3 the poster inserted a non-certified 1G single-mode WDM (BiDi) SFP, 20 km, TX 1550 / RX 1310 nm with DDM, into ge-0/0/1. The interface never appeared: show interfaces returned error: device ge-0/0/1 not found, and the log recorded XCVR: Unit 1, Fibre channel transceiver plugged in without Fibre channel configuration. The poster wanted to know why the Ethernet optic was treated as a Fibre Channel module.

  • Hardware: Juniper EX4600
  • Transceivers: third-party 1G BiDi SFP TX1550/RX1310 20 km
  • Form factor: SFP

Symptoms / messages:

error: device ge-0/0/1 not found
XCVR: Fibre channel transceiver plugged in without Fibre channel configuration

Accepted answer

The module EEPROM is coded incorrectly and advertises Fibre Channel compliance instead of 1000BASE Ethernet, so the switch treats it as an FC optic; a properly coded 1G Ethernet SFP is needed.

Juniper generally tolerates third-party optics, but a respondent claimed WDM/BiDi types are not supported at all on this platform.
