Gecko Structure pluggable POB Parallel Transceiver Module

Gigac Technology's Gecko-based pluggable parallel optical modules (POB) are optical communication solutions designed for high-performance, high-reliability scenarios. Fully compatible and interchangeable with traditional fixed-fiber POB modules, they offer flexible deployment and rapid upgrades, making them particularly suitable for high-speed data transmission in demanding environments.

Product Features:

Single-channel speeds supported: 155M, 1.25G, 2.5G, 6G, 10G, 16G, 25G, and more.

Parallel fiber channel configurations supported: 4 transmitters, 4 receivers, 4 transmitters, 4 receivers, 8 transmitters, 8 receivers, 12 transmitters, 12 receivers, 24 transmitters, and 24 receivers.

Gecko Structure LCC Module Pigtail Assembly (Pigtail end interface can be customized, standard is MT interface)

(1) The module pigtail can be assembled after the module body is properly installed, or the pigtail can be assembled in advance and then installed on the mainboard. The pigtail inserted into the module side is a dedicated pluggable 1*12 core jumper, as shown in the yellow part in the figure below.

(2) The recommended assembly sequence is as follows:

1. Gently press down the spring clip on the top of the module body, then insert the pigtail. Note that the jumper needs to be inserted in the direction shown in the figure. Refer to the figure below:

2. After inserting the pigtail, release the top spring clip and inspect the optical port to ensure the spring clip is properly engaged with the pigtail's MT connector. When properly assembled, the spring clip should be approximately engaged with the left and right shoulders of the jumper connector, as shown in the figure below.

3. After the pigtail is properly secured, tighten the screw in the center of the spring clip to secure it securely. Refer to the diagram below.

After the pigtail is assembled, the remaining pigtail length WL=L-(4.7±0.5) mm, refer to the figure below：

Pigtail length code table:

Note:

For pigtail lengths ≥50mm, flat, round, and loose fiber options are available, with springs or guide pins.

For pigtail lengths <50mm, flat fiber options are available without springs.

The standard pigtail length tolerance is ±L*5%.

Special requirements will be discussed separately.
