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.
This module is hot-swappable and interoperable with Juniper MX, M, T, PTX and compatible third-party switches and routers supporting XFP MSA standards.
It supports single-mode fiber (SMF) for link spans up to 40 km when using an optical budget of at least 3 dB.
It uses a central wavelength of 1490 nm within the CWDM ITU-T G.694.2 grid.
Yes. It meets IEEE 802.3ae 10GBASE-ER, XFP MSA, CWDM MSA and RoHS-6 directives.
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.
Typical power consumption is <2.5 W. Operating temperature ranges from 0 °C to 70 °C; storage from –40 °C to 85 °C.
Use Juniper’s show interfaces diagnostics optics <interface> command to check optical power, temperature, and laser bias current.
No. CWDM and DWDM operate on different channel spacings and are not interoperable in the same fiber pair.
We offer a lifetime warranty covering defects in materials and workmanship, with free replacements for faulty units.
No. It is plug-and-play and auto-negotiates 10 Gbps link parameters; manual configuration is only needed for advanced optical diagnostics.
Check fiber cleanliness, verify correct polarity, confirm transceiver compatibility, and inspect optical power levels via diagnostics.
Modules ship in antistatic trays or individual clamshells. We offer next-day, 2-day and standard ground shipping worldwide.
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.
Yes. The XFP-10GE-ER-1491-C supports hot-plug removal and insertion without powering down the entire system.
With a low power draw of under 2.5 W and RoHS-compliant components, it minimizes operational costs and environmental impact.
