Description
Product Overview
The EtherWAN EX-LS48-C3U-TC-N57-CE is an 80 km Gigabit SFP fiber transceiver for long-distance links over 9/125 µm single-mode cable. Its single LC BiDi interface transmits at 1570 nm and receives at 1510 nm, while Digital Diagnostic Monitoring (DDM) supports compatible network management equipment. The TC variant is rated for commercial operating temperatures, not hardened environmental conditions. Confirm the optical pairing and product lifecycle before purchasing.
The EtherWAN EX-LS48-C3U-TC-N57-CE is a non-hardened Gigabit single-fiber SFP transceiver offered by Coremicro. EtherWAN specifies a rated 80 km reach, single LC connector, 1570 nm transmit wavelength, 1510 nm receive wavelength, DDM, 24 dB optical link budget, -2 to +3 dBm output power and -26 dBm receiver sensitivity. The operating temperature range is 0°C to +70°C. EtherWAN announced this model in an End-of-Life notice dated September 1, 2026; confirm order eligibility, price, warranty and availability with Coremicro.
80 km Single-Mode Fiber Reach
The rated 80 km Gigabit fiber link uses 9/125 µm single-mode cable. Check fiber attenuation, connectors, splice loss and spare optical margin before specifying a route; distance alone does not prove that a link will work.
1570 nm TX and 1510 nm RX BiDi Optics
This single-fiber transceiver sends at 1570 nm and receives at 1510 nm. The far-end module must use compatible complementary wavelengths, typically 1510 nm TX and 1570 nm RX, and meet the full optical requirements.
Single LC Fiber Connection
The single LC interface carries bidirectional communication over one fiber strand. It is not a duplex LC module; verify the connector, installed cabling and remote optics before ordering.
Digital Diagnostic Monitoring
DDM allows supported host equipment to present optical diagnostic readings for troubleshooting. The exact measurements and management functions available depend on the network switch or other host.
Commercial-Temperature SFP Module
EtherWAN classifies the TC model as non-hardened, with an operating temperature of 0°C to +70°C. Do not select it for an installation requiring a -40°C to +85°C hardened optic without choosing a separately rated model.
Lifecycle and Replacement Planning
EtherWAN listed this model in an End-of-Life notice dated September 1, 2026. Confirm order eligibility, remaining supply, manufacturer support and appropriate alternatives with Coremicro before designing a new deployment.

Long-Distance Ethernet Fiber Links
Plan an 80 km single-mode fiber route between compatible Gigabit switches or media converters. Validate total link loss and SFP support at both endpoints.
Single-Fiber Building Connections
A single LC BiDi connection can use one optical fiber strand to connect compatible network locations. Confirm that the far-end optic uses the complementary 1510/1570 nm wavelength pairing.
DDM-Assisted Optical Troubleshooting
Technicians can review diagnostic readings exposed by compatible host equipment. For existing installations, confirm lifecycle status before ordering an identical spare.
Network Engineers
For optical link-budget calculations, correct BiDi wavelength pairing and compatible Gigabit SFP ports.
Systems Integrators
For network infrastructure projects requiring a single-fiber 80 km Ethernet connection.
Industrial IT Teams
For installations that meet the commercial 0°C to +70°C operating range and need validated SFP compatibility.

What is the EtherWAN EX-LS48-C3U-TC-N57-CE used for?
The EtherWAN EX-LS48-C3U-TC-N57-CE is an 80 km Gigabit SFP transceiver for 9/125 µm single-mode fiber. It provides a single LC BiDi connection and supports Digital Diagnostic Monitoring.
Which TX and RX wavelengths does this BiDi SFP use?
This BiDi SFP transmits at 1570 nm and receives at 1510 nm through a single LC connector. A compatible remote optic must use complementary wavelength directions.
Does the EX-LS48-C3U-TC-N57-CE support DDM?
The EX-LS48-C3U-TC-N57-CE supports Digital Diagnostic Monitoring (DDM). Host equipment must expose the relevant readings for operators to use them.
Is the EtherWAN TC model hardened for outdoor temperatures?
The EtherWAN TC model is non-hardened and is specified for 0°C to +70°C operation. A -40°C to +85°C environment requires an appropriately rated hardened transceiver.
What is the difference between the N57-CE and N51-CE models?
The N57-CE transmits at 1570 nm and receives at 1510 nm; the N51-CE transmits at 1510 nm and receives at 1570 nm. Both are 80 km single LC models, with complementary wavelength arrangements for a compatible BiDi link.
Can this EtherWAN SFP work with any Gigabit Ethernet switch?
This EtherWAN SFP requires a host port and firmware that support its optics. Confirm single LC, the complementary BiDi wavelength pairing, optical budget and host compatibility before purchasing.
Is Coremicro an authorized EtherWAN dealer?
Coremicro displays an Authorized Dealer designation on its EtherWAN product listing. Buyers should confirm current authorization, warranty terms and product availability directly with Coremicro.
