Modular Fiber Switch, 16-Port (with Rackmount Kit) (RoHS certified)


Please call 877-877-2269 for a replacement product or part.


  • All RJ-45 module ports are 10/100 switching and 10-/100-Mbps autonegotiating.
  • RoHS-compliant.
  • All ports support half- and full-duplex modes.
  • Silicon-based switching (ASIC).
  • Store-and-forward switching.
  • Self-learning address tables.
  • Full-speed filter and forwarding across all ports.

  • Need to increase the efficiency of your large Ethernet LAN? Segment it into subnetworks with a high-powered, flexible BLACK BOX® Modular Fiber Switch.

    Choose your chassis.
    Three chassis styles are available: 8-port, 8-port rackmount, and 16-port. A 16-port RoHS-compliant model is also available. All four models can be configured with as few as four ports. Then you can add modules according to the demands of your network—without breaking your budget.

    Make a melting pot of media and speeds.
    Our Mixed Media Fiber Switches offer maximum flexibility for your network because you can configure any combination of fiber and RJ-45 modules and 10-Mbps, 10-/100-Mbps, and 100-Mbps speeds. You can install any module in any slot in any chassis. A wide variety of 4-port modules is available.

    Choose from:
  • 10- and 100-Mbps multimode fiber (LE1424C, LE1428C, LE1419C, LE1422C-LE1423C).
  • 10-/100-Mbps twisted-pair (LE1425C).
  • 100-Mbps single-mode fiber (LE1421C, LE1421C-40K).
  • 10-/100-Mbps mixed-media (LE1426C, LE1426C-SM, LE1427C)

    Set up in a flash.
    Network changes and additions are quick and easy with the self-learning Modular Fiber Switch. These switches automatically learn and maintain the addresses of attached nodes. The addresses are stored in a 24K-node address table that's large enough to support your bulging LAN. Plus, an 8 MB packet buffer yields advanced performance, even with unbalanced loads.

    To top it all off, the internal, autosensing power supply operates both in the U.S. and internationally. You can set it up quickly and easily anywhere you have an AC-powered connection.

    Transmit error-free data efficiently.
    The Modular Fiber Switches feature store-and-forward switching on all ports. They read each complete data packet into an internal buffer, temporarily storing it and checking it against the individual switch's internal address list. The entire packet undergoes an error-checking procedure to validate its integrity. Once verified, the packet is then forwarded from the buffer to the appropriate destination device. And because faulty packets are filtered out, traffic congestion is minimized.

    Any media, any speed, any network, anywhere.
    For truly versatile networking, populate a Modular Fiber Switch. With the option of 4, 8, 12, or 16 fiber or twisted-pair ports at your choice of speeds, you can't go wrong. It's the ideal migration path from 10-Mbps to 100-Mbps and from twisted pair to fiber.
