10 GBPS bidi SM SF 1330nm/ 1270nm 20 KM LC DDM

Description

10Gbps BiDi SFP+ Optical Transceiver – 1330nm/1270nm, LC Connector, 20km with DDM

The 10 GBPS bidi SM SF 1330nm 1270nm 20 KM LC DDM optical transceiver module is a high-performance, cost-effective solution for long-distance data transmission over single-mode fiber (SMF). Using bidirectional (BiDi) transmission technology, this transceiver enables full-duplex communication over a single fiber by using 1330nm for transmitting and 1270nm for receiving signals. It is specially designed for 10GBASE-BX Ethernet applications and is ideal for deployments in enterprise backbones, data centers, metropolitan networks, and telecom access systems.

Compact in size and compatible with standard SFP+ interfaces, this module supports hot-pluggability, advanced digital diagnostic monitoring (DDM), and seamless integration with major networking brands. It conforms to the SFP+ MSA (Multi-Source Agreement) and IEEE 802.3ae 10GBASE-BX20 specifications.

Key Features

---

1. 10Gbps High-Speed BiDi Transmission

This transceiver module delivers reliable 10 Gigabits per second (Gbps) full-duplex data transmission over a single optical fiber. With a BiDi design, it significantly reduces fiber usage while maintaining performance—making it ideal for:

• High-density networks

• Enterprise interconnects

• Metro Ethernet applications

• FTTx and broadband infrastructure

The 10GBASE-BX20 standard ensures consistent, high-bandwidth connectivity for demanding network environments.

2. BiDi Wavelength Pairing – 1330nm TX / 1270nm RX

This BiDi module transmits at 1330nm and receives at 1270nm, and is used in pairs with a complementary module (1270nm TX / 1330nm RX). This wavelength division multiplexing approach allows for two-way communication on a single strand of fiber, cutting cable requirements in half and reducing installation complexity and costs.

---

3. Transmission Distance of 20km

The module supports a reach of up to 20 kilometers over standard single-mode fiber (SMF), offering flexibility for medium- to long-range networking needs such as:

• Campus backbone links

• Data center interconnections

• Enterprise-to-branch connections

• Telecom access networks

Its long-distance capability makes it suitable for modern network demands without the need for signal repeaters.
