Q
What is a Juniper EX Series Compatible XFP CWDM module?
A
A Juniper EX Series Compatible XFP CWDM module is a hot-pluggable transceiver optimized for Coarse Wavelength Division Multiplexing on Juniper EX switches, delivering cost-effective multi-channel fiber links up to 80 km.
Q
Which Juniper EX Series switches support XFP CWDM modules?
A
Juniper EX Series switches with XFP ports—such as the EX 4200, EX 4300, EX 4500, EX 8200 and EX 9200—fully support Compatible XFP CWDM modules for flexible uplink and distribution links.
Q
What wavelengths are available for Juniper EX Series Compatible XFP CWDM?
A
These modules are available in standard ITU-T G.694.2 CWDM wavelengths from 1270 nm to 1610 nm, enabling up to eight distinct channels per fiber pair.
Q
What is the maximum transmission distance of CWDM XFP modules?
A
Juniper EX Series Compatible XFP CWDM modules support single-mode fiber distances up to 80 km, depending on the channel wavelength and fiber attenuation.
Q
How do I install a CWDM XFP module on my Juniper EX switch?
A
To install, insert the CWDM XFP module into an empty XFP port, secure the latch, connect LC duplex fiber cables, and verify link status via the switch CLI or Junos OS.
Q
Are Juniper EX Series XFP CWDM modules hot-swappable?
A
Yes, these Compatible XFP CWDM transceivers are hot-swappable, allowing you to add or replace modules without powering down the switch.
Q
How does CWDM differ from DWDM in Juniper XFP modules?
A
CWDM uses wider channel spacing (20 nm) for lower cost and simpler cooling, while DWDM employs narrower spacing (0.8 nm) for higher channel counts over longer distances.
Q
Do Juniper-compatible CWDM XFP modules support Digital Diagnostics Monitoring?
A
Yes, they support real-time Digital Diagnostics Monitoring (DDM) for optical power, temperature, and voltage via the switch’s management interface.
Q
Can I mix CWDM and DWDM modules in the same Juniper EX chassis?
A
Mixing CWDM and DWDM transceivers in the same chassis is not recommended due to incompatible channel spacings and optical filtering requirements.
Q
What is the power budget for Compatible XFP CWDM modules?
A
The typical optical power budget ranges from –1 dBm to +4 dBm transmit and –20 dBm receiver sensitivity, yielding a link budget of approximately 16 dB.
Q
Are third-party CWDM XFP modules fully certified for Juniper EX Series?
A
High-quality third-party modules undergo rigorous compatibility and interoperability tests to ensure full Juniper EX Series certification and reliable performance.
Q
What use cases benefit most from Juniper EX Series CWDM?
A
Ideal use cases include metro aggregation, campus interconnects and data center spine-leaf uplinks where cost-effective multi-channel fiber is required.
Q
How can I troubleshoot low signal or link loss on a CWDM XFP?
A
Check fiber cleanliness, connector integrity, correct wavelength matching, and DDM readings in the Junos OS to pinpoint optical power issues.
Q
Can I use CWDM XFP modules on single-mode and multi-mode fiber?
A
These CWDM XFP transceivers are designed exclusively for single-mode fiber; they are not compatible with multi-mode fiber connectors or cabling.
Q
What temperature range do Compatible XFP CWDM modules support?
A
Standard modules operate from 0 °C to 70 °C, while industrial-grade versions cover –40 °C to 85 °C for extreme environments.
Q
What warranty and lead time apply to Juniper EX Series Compatible XFP CWDM?
A
Most suppliers offer a one-year warranty with next-business-day lead times on stocked modules and 2–4 weeks on custom wavelengths.
