When Worlds Collide: Chocolate and Peanut Butter
Jun 30, 2016

How often has it happened to you? You're walking down the street, listening to your favorite ABBA cassette, eating a jar of peanut butter and WHAM!  - some dude in a ridiculous shirt plows into you with his saliva-covered candy bar.

Not something you see every day, but it could happen. Sometimes wacky things happen in packet-optical networks, too.
 
Two great tastes that taste great together?

 

Readers of this blog know we're largely focused on the technologies and applications associated with packet-optical transport. The term packet-optical gets thrown around a lot, but it's really just a term coined to describe DWDM interfaces integrated directly into a router or switch.
 
The other realm of DWDM transport is built using traditional "disaggregated" systems. These stand-alone platforms (sometime referred to as optical shelves) are fully autonomous. Transponder  & muxponder blades pass traffic to/from a switch/router via standard grey Ethernet client ports and transport that data over DWDM interface(s) on the line side. 
 
Almost always, the DWDM links are deployed as 'bookended' solutions, i.e. the same equipment is used at each end of the link. Does it always need to be that way? Can you mix & match?
 
Hey! You got your chocolate in my peanut butter!

Enter the BTI7800 series of optical transport platforms from Juniper. With the recent acquisition of BTI Systems, Juniper now offers both packet-optical and disaggregated transport solutions.
 
Both systems support 100G coherent DWDM transport using common DSP/FEC technologies, but do they taste great together? That all depends if you have the right ingredients. Let's review your options:
  
  
  • Chocolate: MIC3-100G-DWDM - Tastes great with peanut butter, can work with honey
  • Peanut Butter: BTI7814/7802/7801 with UFM3 transponder (100G CFP client optics) -  Tastes great with chocolate, honey isn't bad either. 
  • Celery: BTI7814/7802/7801 with UFM3 muxponder (10x10GE SFP+ client optics) - Works with peanut butter, adds crunch.
  • Honey: CFP-100GBASE-ZR - Chocolate & peanut butter work but don't even think about celery.
  • Mac N' CheetosTM: P1-PTX-100G-DWDM - In a class all by itself
 
Pair with Care

 

There are good reasons why some pairings work and some do not. That said, it certainly helps to know ahead of time and save yourself some disappointment (or nausea). Hopefully the combinations speak for themselves, but when in doubt it's a good idea to ask for advice before placing your order.
 
For those of you who want to put chocolate on your celery, you've been warned.
