Key Features of Ciena 12821 Compatible LINK-PP 10G SFP+
The Ciena 12821 Compatible LINK-PP module is an efficient 10GBASE-BX SFP+ BiDi optical transceiver engineered to maximize bandwidth and save fiber resources over long distances. It integrates advanced bidirectional signaling, real-time diagnostics, and standard simplex connectivity to deliver reliable 10Gbps networking.
This compact transceiver utilizes bidirectional (BiDi) technology to allow simultaneous transmit and receive functions over a single optical fiber. It effectively doubles your network capacity without requiring the installation of new fiber-optic cables.
12821: 10 Gbps Connectivity for Enterprise Fiber Uplinks
This BiDi SFP module provides a reliable, high-speed 10Gbps backbone link that optimizes data traffic between corporate campus switches and core routers. It serves as an ideal solution for scaling enterprise local area networks and data center aggregations.
12821 Module with 1330nm-TX and 1270nm-RX Wavelength
By transmitting data at 1330nm and receiving at 1270nm, the module prevents signal interference on a single fiber strand. This precise wavelength separation ensures clean, full-duplex communication over a single-mode connection.
12821 Module Supporting 20km Transmission
Equipped with a powerful optical transmitter, this transceiver maintains excellent signal integrity over distances up to 20km. This makes it perfect for connecting geographically separated enterprise buildings or regional network hubs.

Bulk ordered 50 pairs of these single-fiber bidirectional optics for our metro aggregation layer deployment. The cost savings on renting dark fiber strands are insane when you switch from dual-fiber to simplex LC optics. Ran a continuous RFC2544 bit error rate test over a 18km single-mode fiber spool—zero errors! Highly recommend this reliable 10GBASE-BX20 module for any ISP or corporate backbone.

If you are managing a regional wireless ISP network, you know how expensive fiber leasing can be. These 10GbE single-mode bidirectional transceivers saved our budget. They work seamlessly across our routers on the towers. The DOM diagnostic features are highly accurate compared to my handheld optical power meter readings. Will definitely buy more for our upcoming ring expansion!
