Frequently Asked Questions
What is a 25G CWDM SFP28 optical transceiver?
It is a hot-pluggable, single-channel optical transceiver module designed for 25G Ethernet and 5G fronthaul CPRI/eCPRI networks, utilizing Coarse Wavelength Division Multiplexing (CWDM) technology to optimize fiber utilization.
What transmission distances do these CWDM SFP28 modules support?
Depending on the specific part number, these transceivers support transmission distances of 10KM (ESCxx2X-10D), 20KM (ESCxx2X-20D), and up to 40KM (ESCxx2X-40D) over Single-Mode Fiber (SMF).
What is the difference between the laser types used in these modules?
The 10KM and 20KM models use a DFB laser transmitter combined with a PIN receiver, which is highly cost-effective for short-to-medium ranges. The 40KM model utilizes an EML laser transmitter and a highly sensitive APD receiver to ensure reliable signal transmission over longer distances.
What connector type and operating temperature range do they support?
All models are equipped with standard duplex LC optical connectors and support a commercial operating temperature range of 0°C to 70°C.
Are these modules compliant with industry standards?
Yes, these SFP28 transceivers are fully compliant with SFP28 MSA standards, IEEE 802.3by, and CPRI/eCPRI specifications, ensuring broad compatibility with major networking hardware.
