Re: SFP options for SRX ( and in fact all Juniper Devices )
CWDM Interfaces, are just SFP's tuned to different wavelengths.. They appear the same to the host equipment. I know that 'another' brand spits and coughs if you try to insert a non 'branded' sfp into their kit.
At the worst, i'll have to put in some external transceivers, its not a show stopper
JNCIA - IDP, WX, EX, UAC JNCIS - FWV, SSL, ER, M, ( because i have to )
