What connector type does this transceiver use?

It uses an LC duplex connector for reliable, low-loss fiber coupling.

Is the DWDM-SFPGE-1551-72 hot-swappable?

Yes. It meets the SFP MSA standard for plug-and-play hot-swap capability without powering down the host.

Which equipment is this module compatible with?

It is interoperable with all MSA-compliant switches, routers, DWDM MUX/DEMUXs and transponders from major vendors.

What is the optical power budget of this transceiver?

The module delivers a typical output power of 0 to +4 dBm with a receiver sensitivity of –24 dBm, yielding a power budget of 24 dB.

What are the operating temperature specifications?

Industrial temperature variant supports –40 °C to +85 °C; commercial version supports 0 °C to +70 °C ambient.

What fiber type is required for optimal performance?

Use ITU-G.652-compliant single-mode fiber (SMF-28) with <0.4 dB/km attenuation at 1550 nm.

How do I install the DWDM-SFPGE-1551-72 in my switch?

Align the module’s ejector latch with the SFP slot, push until it clicks, then secure the LC fiber connector.

What power consumption does this SFP draw?

Typical power consumption is 1.0 W, maximum 1.2 W, compliant with SFP MSA power classes.

Does the module support digital diagnostics (DDM)?

Yes. It offers real-time monitoring of optical output/input power, temperature, voltage and laser bias current via I²C.

How does DWDM differ from CWDM in this context?

DWDM uses narrower channel spacing (100 GHz) for higher channel density over single fiber, while CWDM offers wider spacing (20 nm).

What warranty covers the DWDM-SFPGE-1551-72 transceiver?

It carries a standard one-year warranty covering defects in materials and workmanship under normal operation.
