Juniper C55 SFP-1G-DW55 Compatible 1G 1000BASE-DWDM SFP Optical Transceiver Module (SMF, C55, 1533.47nm, 80km, LC, DDM)


Juniper C55 SFP-1G-DW55 compatible 1000BASE-DWDM SFP series 1G SFP transceiver module is equipped with an LC duplex connector, supporting 1.05-1.25Gbps data rate at a link length up to 80km over dual fiber single-mode fiber (SMF). This 1G DWDM SFP transceiver operates at a nominal DWDM wavelength from 1528nm to 1566nm (C17-C61) as specified by the ITU-T, designed for DWDM networking equipment connectivity.


QSFPTEK manufactured 1000BASE-DWDM 1G SFP module is compliant with the SFP Multi-Source Agreement (MSA) specifications. Besides, the small form-factor pluggable (SFP) optic has been tested on host devices to ensure full compatibility with multi-vendor (Cisco, Juniper, Arista, etc.) equipment, such as Ethernet switches, enterprise routers, and server network interface cards (NICs). The third-party DWDM 1G SFP module is an ideal substitute to the branded DWDM 1G SFP transceiver at an affordable price, providing a cost-effective compatible solution for high-performance 1G Ethernet connectivity.


DWDM 1G SFP optics cater to 1 Gigabit Ethernet (1GbE) optical fiber connections, ideal to be deployed for long-haul DWDM Solutions in metropolitan access and core networks.

Questions & Answers

  • I want to order some DWDM SFP+ modules, and I found that there are two different transceivers tunable DWDM SFP+ and fixed-wavelength DWDM SFP+ in QSFPTEK. What's the difference between these two DWDM modules?
    Actually, there is not much difference in their wavelengths. The tunable DWDM transceiver module works at a 50GHz C-band wavelength with a pitch of 0.4nm. The fixed-wavelength DWDM transceiver supports 50GHz (0.4nm spacing) and 100GHz (0.8nm spacing) C-band wavelengths. And 50GHz channel includes a 100GHz channel, so 50GHz tunable DWDM can also operate on a 100GHz wavelength. Tunable transceivers can reduce the need for inventory of DWDM SFP+ transceivers, to save costs and maximize network flexibility. You can use this module to link any port of the same DWDM MUX over an optical cable. If you buy a tunable module, you can also tune the wavelength of the tunable transceiver.
  • Can DWDM-SFP10G be worked with Multi-Mode fiber(MMF)?
    No, the DWDM SFP 10G can't be worked with MMF, they can only work with Single-mode fiber.

  • Agnes B. United States of America

    We wanted to create a complete building-to-building link, so we needed a lot of SFP DWDM optical modules, which had to be cost-effective. After I sent them our project, QSFPTEK gave me a complete connection diagram and gave us a fiber loss calculation to match the fiber. After that, we ordered the 1G DWDM optical module from QSFPTEK. Everything is good now, we haven't met any questions till now.
