Questions & Answers
What is the DWDM X2 1544.53 nm X2 (100 GHz ITU grid) module?
The DWDM X2 1544.53 nm X2 is a 10 Gbps hot-pluggable X2 transceiver compliant with the 100 GHz ITU channel grid, engineered for high-density DWDM networks.
Which data rates and protocols does this module support?
It supports 9.95–10.7 Gbps line rates and is fully interoperable with 10 Gigabit Ethernet (10GBASE-DWDM) and SONET/SDH standards.
What fiber type and connector interface are required?
The module uses single-mode fiber (SMF) and is equipped with a duplex LC connector interface for both transmit and receive channels.
What is the maximum transmission distance?
On standard SMF (0.2 dB/km), it delivers up to 80 km reach without the need for in-line amplifiers or dispersion compensation.
What are the optical power and sensitivity specifications?
Transmit power ranges from –2 to +4 dBm, receiver sensitivity is –23 dBm, yielding an optical budget of approximately 20 dB.
Which ITU channel and grid spacing does it adhere to?
It operates on the 44th ITU channel at 1544.53 nm with standard 100 GHz spacing, ensuring precise wavelength alignment.
Is the module hot-swappable?
Yes. The X2 form factor is hot-pluggable, allowing insertion or removal without powering down the host device.
What operating temperature range is supported?
Industrial-grade operation from 0 °C to +70 °C ambient temperature ensures reliable performance in diverse environments.
Does it support Digital Diagnostic Monitoring (DDM)?
Yes. On-board DDM provides real-time monitoring of optical power, temperature, voltage, and laser bias current via the I²C interface.
Is the DWDM X2 module MSA-compliant?
Absolutely. It meets SFF-8431, SFF-8432, and SFF-8472 specifications for X2 transceivers, ensuring broad vendor interoperability.
Can it be used in CWDM networks?
No. This module is purpose-built for DWDM applications and does not support coarse wavelength-division multiplexing (CWDM).
Which networking equipment is it compatible with?
It’s fully interoperable with X2 ports on leading vendors’ switches, routers, and transport platforms, including Cisco, Juniper, Arista, and HP.
What warranty and support are provided?
The module carries a 5-year limited warranty and includes lifetime technical support and free firmware updates.
How do I install this DWDM X2 module?
Align the module with an empty X2 slot, insert until it clicks, and verify the link via your host device’s SFP interface status.
