Other Optical Transceivers
Other optical transceivers include legacy, specialized, and application-specific modules that continue to play an important role in telecom, industrial, broadcast, and utility networks. These transceivers are designed for systems that require fixed form factors, lower data rates, or specialized optical interfaces not covered by modern pluggable SFP, QSFP, or OSFP standards. All applicable modules comply with relevant industry specifications and meet CE, FCC, and RoHS requirements. Digital diagnostics are available on select models depending on form factor and application.

Product Overview and Typical Specifications
1×9 Transceivers
1×9 modules are fixed-form optical transceivers commonly used in legacy telecom, industrial, and access equipment. Typical supported data rates include 155 Mbps, 622 Mbps, and 1.25 Gbps, depending on application. Available in multimode and single-mode variants, transmission distances typically range from 2 km and 10 km to 40 km, 80 km, and up to 120 km for long-haul single-mode designs. These modules are often selected where hot-swappable interfaces are not required.
1×9 BIDI Transceivers
1×9 BIDI transceivers support bidirectional transmission over a single fiber strand using different wavelengths for transmit and receive. Typical data rates include 155 Mbps, 622 Mbps, and 1.25 Gbps, with transmission distances commonly ranging from 10 km to 40 km, 80 km, and up to 120 km, depending on optical budget. These modules are used to reduce fiber usage in access networks and industrial installations.
SFF Transceivers
SFF (Small Form-factor Fixed) transceivers provide compact optical connectivity for legacy platforms requiring fixed optical interfaces. Typical supported data rates include 100 Mbps, 155 Mbps, and 1.25 Gbps. Multimode SFF transceivers usually support distances of 550 m, while single-mode versions commonly support 2 km, 10 km, and up to 40 km.
SFF BIDI Transceivers
SFF BIDI transceivers extend standard SFF designs by enabling single-fiber bidirectional communication. Typical data rates include 155 Mbps and 1.25 Gbps, with transmission distances ranging from 10 km to 40 km, depending on wavelength pairing and optical power levels. These modules are often used in fiber-limited access and control networks.
CSFP Transceivers
CSFP (Compact Small Form-factor Pluggable) transceivers integrate two independent optical channels into a single SFP slot. Each channel typically operates at 1.25 Gbps, providing an effective aggregate capacity of 2.5 Gbps per slot. Transmission distances are similar to standard SFP modules and commonly include 10 km, 20 km, 40 km, and up to 80 km over single-mode fiber. CSFP modules are used to increase port density in access and aggregation networks.
Video Optical Transceivers
Video optical transceivers are designed for broadcast, surveillance, and industrial video transmission applications. Typical supported formats include SD, HD, and 3G video, corresponding to data rates up to approximately 3 Gbps. Transmission distances vary by application and fiber type, with common ranges of 10 km, 20 km, and up to 40 km over single-mode fiber. These modules are optimized for low latency and stable signal performance rather than packet-based networking.
Performance and Reliability
Depending on product type, these transceivers support multimode and single-mode fiber with transmission distances ranging from short-reach links to long-distance applications exceeding 100 km. Each module is tested for optical performance, signal integrity, and interoperability with target platforms to ensure reliable operation in commercial and industrial environments.
Designed to support both legacy systems and specialized applications, NAFO/Coretek’s other transceiver solutions provide dependable optical connectivity, extended lifecycle support, and cost-effective integration for networks with unique or non-standard requirements.
