SFP with DDM（Digital Diagnostic Monitoring）1.25G Optical Transceiver Module

Description

This 1.25G SFP with DDM optical transceiver module is engineered for reliable, long-distance data transmission in demanding network environments. A key selling point is its integrated Digital Diagnostic Monitoring (DDM) function, which allows for real-time performance tracking of parameters like temperature, optical power, and voltage, enabling proactive network maintenance and reducing downtime. Fully compliant with SFP MSA and SFF-8472 standards, this hot-pluggable module guarantees seamless compatibility with a wide range of major network equipment brands, including Cisco and Huawei switches. It supports data rates up to 1.25Gb/s for applications like Gigabit Ethernet and 1x Fiber Channel, transmitting over distances up to 20km on single-mode fiber using a 1310nm FP laser. SFP with DDM designed with a metal enclosure for superior EMI protection and featuring low power consumption, this transceiver is a robust and efficient solution for enhancing switch-to-switch interfaces, router/server connections, and backbone network stability.

SFP with DDM FEATURES:

• Real-Time Network Monitoring: The built-in Digital Diagnostic Monitoring (DDM/DOM) interface provides vital, real-time insights into the transceiver’s operating conditions, including temperature, laser bias current, transmitted and received optical power, and supply voltage.
• Broad Multi-Vendor Compatibility: Designed to the SFP MSA (Multi-Source Agreement) standard, this module ensures reliable interoperability and is a compatible SFP transceiver for switches and routers from leading manufacturers like Cisco, Huawei, and others.
• Robust Performance for Enterprise Networks: Supports high-speed 1.25G Gigabit Ethernet and 1x Fiber Channel applications. It features a high-performance 1310nm FP laser transmitter and a duplex LC connector, achieving stable transmission up to 20km on standard 9/125μm single-mode fiber (SMF).
• Enhanced Reliability & Safety: Constructed with a metal enclosure for effective electromagnetic interference (EMI) shielding and improved durability. It complies with Class 1 laser safety standards (IEC-60825) and includes TX Disable and Loss of Signal (LOS) alarm functions for secure operation.
• Efficient & Hot-Pluggable Design: Features a hot-pluggable footprint for easy installation and removal without powering down the system. It operates on a single 3.3V power supply with typically low power dissipation of under 700mW, promoting energy efficiency.

Notes:

1. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
2. Also specified to meet curves in FC-PI 13.0 Figures 18 and 19, which allow trade-off between

wavelength, spectral width and OMA.

3. Equivalent extinction ratio specification for Fiber Channel. Allows smaller ER at higher average power.
4. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x and 2x eye masks when filtered.
5. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ andDDJ.
6. Measured with conformance signals defined in FC-PI 13.0 specifications.
   7. Measured with PRBS 27-1 at 10-12 BER
