Questions & Answers
Q
What is the XFP-10GE-ER-1491-C?
A
The XFP-10GE-ER-1491-C is a 10GBASE-CWDM XFP transceiver module operating at 1490 nm, designed for 40 km single-mode fiber links and fully compatible with Juniper MX and T-series routers.
Q
Which devices support the XFP-10GE-ER-1491-C?
A
This module is hot-swappable and interoperable with Juniper MX, M, T, PTX and compatible third-party switches and routers supporting XFP MSA standards.
Q
What fiber type and distance does it support?
A
It supports single-mode fiber (SMF) for link spans up to 40 km when using an optical budget of at least 3 dB.
Q
What wavelength does the transceiver use?
A
It uses a central wavelength of 1490 nm within the CWDM ITU-T G.694.2 grid.
Q
Is the module compliant with industry standards?
A
Yes. It meets IEEE 802.3ae 10GBASE-ER, XFP MSA, CWDM MSA and RoHS-6 directives.
Q
How do I install the XFP-10GE-ER-1491-C?
A
Power down the port (if required), insert the module into an XFP port until it clicks, then restore the port and verify link status via the router’s CLI or GUI.
Q
What are the power and temperature specifications?
A
Typical power consumption is <2.5 W. Operating temperature ranges from 0 °C to 70 °C; storage from –40 °C to 85 °C.
Q
How do I verify link status after installation?
A
Use Juniper’s show interfaces diagnostics optics <interface> command to check optical power, temperature, and laser bias current.
Q
Can I mix this CWDM transceiver with DWDM equipment?
A
No. CWDM and DWDM operate on different channel spacings and are not interoperable in the same fiber pair.
Q
What is the warranty for the XFP-10GE-ER-1491-C?
A
We offer a lifetime warranty covering defects in materials and workmanship, with free replacements for faulty units.
Q
Does the module require additional configuration?
A
No. It is plug-and-play and auto-negotiates 10 Gbps link parameters; manual configuration is only needed for advanced optical diagnostics.
Q
How do I troubleshoot a non-working link?
A
Check fiber cleanliness, verify correct polarity, confirm transceiver compatibility, and inspect optical power levels via diagnostics.
Q
What packaging and delivery options are available?
A
Modules ship in antistatic trays or individual clamshells. We offer next-day, 2-day and standard ground shipping worldwide.
Q
How does this ER module differ from an SR module?
A
ER (Extended Reach) uses 1490 nm for 40 km SMF, while SR (Short Reach) uses 850 nm for up to 300 m over multimode fiber.
Q
Is this transceiver hot-swappable?
A
Yes. The XFP-10GE-ER-1491-C supports hot-plug removal and insertion without powering down the entire system.
Q
How energy-efficient is the XFP-10GE-ER-1491-C?
A
With a low power draw of under 2.5 W and RoHS-compliant components, it minimizes operational costs and environmental impact.
