Description
Product Overview
The EtherWAN EX-LS48-C3U-TC-N51-CE is an 80 km Gigabit SFP transceiver for long-distance links over 9/125 µm single-mode fiber. Its single LC bidirectional interface transmits at 1510 nm and receives at 1570 nm, while Digital Diagnostic Monitoring (DDM) provides diagnostics through compatible host equipment. This non-hardened TC model operates from 0°C to +70°C. Confirm wavelength pairing, host compatibility and product availability before ordering.
The EtherWAN EX-LS48-C3U-TC-N51-CE is a non-hardened Gigabit Ethernet single-fiber SFP module listed by Coremicro. EtherWAN specifies 80 km rated reach, 9/125 µm single-mode fiber, a single LC connector, 1510 nm transmit and 1570 nm receive wavelengths, DDM, a 24 dB optical link budget, -2 to +3 dBm transmitter output and -26 dBm receiver sensitivity. The operating temperature range is 0°C to +70°C. EtherWAN named the model in an End-of-Life notice dated September 1, 2026. Confirm current price, availability and applicable manufacturer warranty with Coremicro.
80 km Single-Mode Fiber Reach
The manufacturer-listed 80 km Gigabit fiber reach supports planning long-distance links between compatible network devices. Confirm attenuation, connector and splice losses, and available optical margin rather than relying on the distance rating alone.
1510 nm TX / 1570 nm RX BiDi Optics
This single-fiber optic transmits at 1510 nm and receives at 1570 nm. It requires a compatible far-end module with complementary 1570 nm TX and 1510 nm RX wavelengths, such as the correctly specified N57-CE counterpart.
Single LC Gigabit SFP Connection
A single LC connector carries transmit and receive signals over one single-mode fiber strand using separate wavelengths. Check the host Gigabit SFP slot, device compatibility and fiber installation before selection.
Digital Diagnostic Monitoring
DDM support can provide optical status information through compatible managed switches or media converters. The specific readings available depend on the host platform and its management interface.
Non-Hardened Operating Temperature
The TC variant is specified for 0°C to +70°C operation. It is not a -40°C to +85°C hardened optic; match the SFP rating to the expected switch and enclosure temperatures.
End-of-Life and Replacement Planning
EtherWAN included this model in its September 1, 2026 End-of-Life notice. Confirm Special Order fulfillment, remaining stock, support coverage and suitable replacements with Coremicro before including it in a new installation.

Long-Distance Ethernet Fiber Links
Connect compatible Gigabit Ethernet equipment over a planned single-mode fiber run. Calculate total optical path loss and verify support for the transceiver at each endpoint.
Single-Fiber Facility Connections
Use a compatible BiDi pair to connect separated buildings or remote cabinets over one fiber strand. Check the actual wavelength pairing and the temperature limits of the installed equipment.
DDM-Assisted Optical Troubleshooting
Review optical diagnostics where supported by the host switch. For existing installations, confirm EOL-related spare availability before replacing a failed optic.

What is the EtherWAN EX-LS48-C3U-TC-N51-CE used for?
The EtherWAN EX-LS48-C3U-TC-N51-CE is an 80 km Gigabit SFP transceiver for 9/125 µm single-mode fiber. It uses a single LC bidirectional connection and supports Digital Diagnostic Monitoring.
Which wavelengths does the EX-LS48-C3U-TC-N51-CE use?
The EX-LS48-C3U-TC-N51-CE transmits at 1510 nm and receives at 1570 nm. A compatible far-end transceiver must use the complementary 1570 nm TX and 1510 nm RX arrangement.
Does this EtherWAN SFP support DDM?
This EtherWAN SFP supports Digital Diagnostic Monitoring (DDM). Diagnostic readings are available when the host switch or media converter provides access to them.
Can this 80 km BiDi SFP operate in hardened temperatures?
The 80 km BiDi SFP is a non-hardened TC model rated for 0°C to +70°C. It is not specified for the -40°C to +85°C hardened operating range.
How does the N51-CE differ from the N57-CE?
The N51-CE transmits at 1510 nm and receives at 1570 nm, while the N57-CE reverses those wavelengths. Both are listed as 80 km, single LC, Gigabit DDM transceivers; confirm the host devices and optical budget before pairing them.
Is the EX-LS48-C3U-TC-N51-CE still available?
EtherWAN included the EX-LS48-C3U-TC-N51-CE in an End-of-Life notice dated September 1, 2026. Coremicro currently lists the product as Special Order, but customers should confirm order eligibility, stock, warranty and alternatives before purchasing.
Is Coremicro an authorized EtherWAN dealer?
Coremicro displays an Authorized Dealer designation on its listing for this EtherWAN SFP. Buyers can contact Coremicro to confirm current authorization and the applicable manufacturer warranty before ordering.
